WARNING
Refers to a potentially hazardous situation which, if not avoided, could result in death or serious injury.
The P12 Battery Charger should be installed by a qualified marine electrician. Improper installation can result in electrical shock which may cause serious
injury or death. To reduce the risk of electrical shock, mount vertically in a dry, well ventilated location. Charge these battery types: Flooded, AGM, Gel, or
TPPL Lead Acid batteries. Consult battery manufacturer specifications for other battery types to avoid damage. This battery charger is not intended for use
by persons (including children) with lack of ability, experience, or knowledge, unless they have been given supervision or instruction concerning use of the
battery charger by a person responsible for their safety. Do not recharge non-rechargeable batteries. Children should be supervised to ensure that they do
not play with the appliance. Avoid serious injury or death from electrical shock, turn off AC supply power before opening terminations cover.
Risk of Explosive Gases
Working in the vicinity of a Lead-Acid battery is dangerous. Batteries generate explosive gases during normal battery operation. Explosive gasses can ignite
and may cause serious injury or death. Ensure battery location is properly ventilated according to battery manufacturer or industry standards. To reduce risk
of battery explosion, follow these instructions and those published by the battery manufacturer. Do not smoke or cause a spark in the area around batteries
and engines. Each time before using your charger read this manual and follow the instructions. Do not use any accessory devices that directly connect to
the charger other than those manufactured by Blue Sea Systems and designed for use with the P12 Battery Charger. Do not operate the charger if it has
been dropped or damaged. Contact Blue Sea Systems on how to proceed. Wear complete eye protection and protective clothing when dealing with lead
acid batteries. Remove personal metal items such as jewelry & rings when working around batteries.
CAUTION
Refers to a potentially hazardous situation which, if not avoided, may result in injury.
Before beginning electrical installation, read the instruction manual. Disconnect all AC and DC power sources. Do not make final connections to the
batteries until DC connections on the charger are made and verified. Do not make or break electrical connections to batteries while charging or for up to
30 minutes after charging. Other than parts accessed under the termination cover, there are no user serviceable parts within the battery charger enclosure.
Contact Blue Sea Systems for servicing. Charge only user selectable type batteries, other types of batteries may burst causing personal injury and damage.
Do not use the battery charger to charge dry cell batteries that are commonly used with home appliance. These batteries may burst and cause injury to
person and damage to property. Never charge a frozen battery.
GROUNDING PRECAUTIONS
Marine battery chargers and inverters have two grounding connections, one from the AC system and one from the DC system. ABYC requires
the AC grounding system to be connected to the DC grounding system through the distribution systems. Additionally, the chargers make
connections to both systems. It is very important the systems be connected properly before the charger is installed. Otherwise the charger
grounding system may become the sole connection between AC and DC ground and it may not be sized large enough to provide system wide
safety function. The AC grounding conductor is the conductor with green, or green with yellow stripe included in the AC power cable and should
be sized the same as the power and neutral conductors (see Table C page 5 for AC wire color). This will connect to the right most terminal in
the AC connection block. There is also chassis connection terminal for a DC safety grounding wire. The DC safety ground should be green or
marked green and sized equal to, or one wire size smaller, than the DC charge wires.
READ AND SAVE THESE INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS This manual contains important safety and operating instructions for battery charger Models 7531 and 7532.
2. Do not expose charger to rain or snow.
3. Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to persons.
4. Do not operate charger with damaged cord – replace the cord immediately.
5. Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified serviceman.
6. Do not disassemble charger; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of
electric shock or fire. The battery charger must be properly assembled in accordance with the assembly instruction before it is used.
7. To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.

The Blue Sea Systems P12 Battery Charger is dry mount device designed for use in marine applications and other harsh environments where
reliability, ease of use, and high performance are of primary importance. The P12 is designed in Bellingham, Washington, USA.
The P12 is designed to charge three electrically independent batteries or battery banks. The P12 has the unique capability to individually move each battery out of the
Absorption charging stage. This ensures batteries near their full charge do not continue to receive high constant voltages necessary in the Absorption stage. This is optimal
treatment for long battery life. Charge Coordination integrates with the Blue Sea Systems family of Automatic Charging Relays (ACR) to force separation of the battery banks
while the P12 is operational, to allow the batteries to individually exit the absorption stage. After fourteen days of continuous Float, the charger will repeat the normal charge
cycle to assure good battery health.
For reliability, the P12 has a rugged cast aluminum housing with high heat dissipating capability for minimum cooling fan run times. The electronic design has given special
consideration to operation in areas of inconsistent AC power quality. The P12 has a Power Factor Corrected nominal AC input range of 115V to 230V AC within which it will
produce its full rated DC charging output. It will continue to produce reduced DC output to as low as 75V AC. After a shut down below 75V AC or when there is interrupted
switching between AC sources, like switching between generator and shore power, the P12 will automatically perform an orderly restart.
Central to the P12’s ease of use is the large plain-language full graphics control screen capable of displaying in French, English, Italian, German and Spanish. The plain
language display enables clear communication with the operator for setting precise charging parameters and providing a broad range of easily understood fault
communications and operating history. An optional remote display brings much of this functionality to a secondary location away from the charger.
The P12 contains charge profiles for most batteries available today, including Flooded Lead Acid (FLA), Gel, Thin Plate Pure Lead (TPPL), and Absorbed Glass Mat (AGM).
In addition, a user configurable charge profile is available for other battery types.
The P12 has built-in safety features including: ignition protection, over and under temperature protection (sensed internally and at the batteries), DC reverse polarity
protection, DC over voltage protection, surge, and short circuit protection.
The definitions of the P12 charging stages are defined below. The charging stage LEDs on the front of the charger will indicate the current stage.
Absorption (Constant voltage)
In the Absorption charging stage the batteries complete their charging by being “topped off”. This is a less aggressive charging stage than Bulk where the current going into a
particular battery bank will significantly reduce with time. The conditions for a battery bank to be considered “full” vary based on many different factors. In order for a battery
bank to leave the Absorption stage a number of different parameters must be met. The main parameters are the Absorption Timers which can be seen on
page 14. Outputs move individually from Absorption to Pre-Float. When all batteries have completed Absorption, the charger will move them into the Float stage.
Float* (Constant voltage)
Float is the final charging stage for fully charged batteries. Batteries in this stage are being maintained at their defined float voltage. Typically Float voltage
has a 1.0V or greater difference from the Absorption voltage.
Pre-Float (Constant voltage)
The Pre-Float charging stage is unique to the P12. Since the size of battery banks typically vary from one output to the next, there is a need to charge each bank independently.
Once all batteries are in Absorption, battery banks may finish charging at different rates. Once a battery bank has met its unique Absorption parameters, the P12 Charger will
independently move it into the Pre-Float stage. Pre-Float is the initial stage to maintain a fully charged battery. Batteries in Pre-Float can have up to a .5V difference
between batteries in Absorption. Up to two outputs can be in Pre-Float simultaneously.
Bulk (Constant current)
The Bulk charging stage is the first stage in the battery charging process. It is where a majority of the charging actually takes place leaving batteries at approximately
75% to 80% of their final capacity. The goal of the Bulk stage is to drive current into the batteries quickly to increase their voltage. Once all the batteries have reached the
defined Absorption voltage, the charger will move them into the Absorption stage.

*Energy Saver Mode (CEC)
a) After the absorption cycle is completed for all outputs, the charger moves to “rest” mode – not float.
b) As the battery(s) rests, the voltage will drop. If loads are active, the voltage will drop more rapidly.
c) When the voltage has dropped to the lower target re-float voltage, the charger will re-start and attempt to enter float mode for a minimum of 4 hours.
d) The charger will enter rest mode again and the cycle will repeat.
NOTE: The CEC test is performed on batteries that have no active loads.

MAINTENANCE INSTRUCTIONS
Periodic Maintenance Items. All other servicing must be performed by qualified service personnel!
Verify P12 Battery Charger screen shows no fault condition and indicates normal operation
Check fuses or circuit breakers to verify like new condition. Confirm no discoloration or corrosion exists and circuit breakers will manually
trip and reset.
Check for proper ventilation and that no debris has collected on the fan shroud or items have been improperly stored around
the P12 Battery Charger.
Check battery terminal connections (both at battery and at the P12 Battery Charger) for corrosion. Clean and reconnect immediately
upon signs of corrosion.
Check batteries per manufacturer’s instructions and maintenance procedures.
Check wire condition. Overheating due to excessively long or too small conductors will result in hardening of the insulation or burn
marks at connections. If any of these signs exist, immediately replace with proper sized conductors.
DC Output Fuse Replacement
Replacement of DC output fuses.
a. CAUTION!! Before replacing output fuses disconnect all sources of AC and all DC batteries and loads from the charger.
If you are not comfortable working on electrical systems, do not proceed. Seek help from a qualified marine electrician.
b. Remove terminations cover from the charger.
c. The fuses are located on the lower right of the charger adjacent to the negative battery stud.
d. Carefully remove both fuses by pulling the fuse straight out from the socket.
e. Replacement fuses must be ATC
®
type fuses with ignition protected rating (use of non-ignition protected rated fuses will render the entire
charger non-ignition protected, and therefore unsafe for use in an environment that requires an ignition protected rating).
Proper fuses are as follows: Model 7531, two 20A ATC
®
Fuses, Model 7532, two 25A ATC
®
Fuses.

Installation & Operating Instructions
Installation Steps
1. Before beginning electrical installation, disconnect all positive and negative AC and DC power sources.
The P12 Battery Charger default startup mode isUser”. The battery charger will maintain a voltage but will not
charge batteries in this mode. After proper installation see page 11 to set up your battery type.
3. The yellow latches are locked/released by turning them ¼ turn with a flat blade screwdriver.
2. To reduce the risk of electrical shock, mount the battery charger vertically, in a dry and well ventilated location.
For drip proof installation, mount the battery charger in a vertical orientation.
NOTE: The charger should be located near the batteries to minimize wire length and its associated voltage drop to maximize charging efficiency.
If the batteries are not close together, place the charger near the largest bank of batteries.
NOTE: DC wiring should safely reach each battery positive and the battery negative common bus bar. Fuses should be installed at the battery positive
connections to prevent battery power from feeding back into a fault in the wiring, or in the battery charger. See Table A and B on page 5 for recommended values.
5. Route DC wires from each charger output to battery fuse holder, see Wiring Connections Diagram page 10.
4. Then remove the AC and DC wire termination strain relief clamps by unfastening the screws.

Absorption Parameters and Timers
14
CAUTION
The default Absorption Timer values are set to satisfy a majority of the battery configurations that exist. Unwarranted changes to Absorption timers could
result in damage to the batteries and reduced battery life. To optimize Absorption Timer based on specific configurations, please contact your
battery manufacturer for setting guidelines for your specific battery.
The Absorption stage is the charging stage in which a battery “fills” to max capacity. Absorption timers help define the amount of time a battery bank will
remain in the Absorption stage. Having a correct Absorption time is vital for optimum charging of a battery bank. Under Absorption can lead to a battery
being consistently under-charged causing sulfate buildup. Over Absorption can dry out the electrolytes in a battery. Both of these conditions can lead to
reduced battery life.
There are three user selectable parameters that help define when a connected battery bank will be moved from Absorption to either Pre-Float, or Float.
Minimum Absorption Time: 1 hour default
The minimum amount of time a battery bank will be in Absorption. The battery charger will not move a battery from Absorb to Float unless the Minimum Absorption Time is met.
Maximum Absorption Time: 4 hour default
The maximum amount of time a battery bank can remain in Absorption. While still maintaining its Absorption voltage, if a battery has been in Absorption for the maximum
designated time it will move into Float even if End Absorb Amps is elevated. This is commonly caused when active loads are present.
Recommended End Absorption Amps
End Absorb Amps will vary based on your specific system. To set the correct End Absorb Amps it is recommended
that you monitor the amperage entering your battery banks near the end of the absorption cycle. Constant loads
will affect this number, and should be incorporated into End Absorb Amps if present. However, in a typical system
(without constant loads) it is recommended that the End Absorb Amps be 1% of your battery banks amp-hour
capacity (see Table F).
End Absorption Amps
The maximum amount of current that a battery bank can receive while in Absorption and still change to Float. If a
load is active and drawing more than the designated End Absorption Amps, the battery bank will not leave Absorption
until the maximum Absorption time is met. For a battery bank to move from Absorption to Float before the maximum
Absorption time is met, the minimum Absorption time must be met, and the amperage output must be less than or
equal to the designated End Absorb Amps.

Recommended Absorption Time
Minimum and Maximum Absorb Times can vary from installation to installation. It is recommended that Minimum and Maximum Absorption Times be based on the time it takes
a battery bank to reach End Absorb Amps. Read and understand the End Absorb Amps section above and set according to your system. After an accurate End Absorb Amperage
is set, monitor the minimum and maximum time it takes for each battery bank to reach their End Absorb Amps. The Minimum Absorb Time should be based on the minimum time
it takes a particular battery bank to reach End Absorb Amps. The Maximum Absorb Time should be an hour more than it takes a deeply discharged battery bank to reach End
Absorb Amps. It is recommended to monitor charging while the battery banks are in different states of discharge to get the most accurate Minimum and Maximum Absorb Times.

Table F: Approximate End Absorb Amps
(1% of Ah Capacity)
Minimum Charge Temperature: The default is 0ºC
The lowest temperature of the sensor in which the charger will continue charging. If the temperature sensor measures below the minimum charge temperature, the charger will
enter standby mode, and cease to charge.
WARNING
Altering the default temperature parameters could cause serious property or personal damage. Contact your battery manufacturer to clarify the correct
temperature parameters for your specific batteries.
NOTE: Temperature parameters refer to the temperature measured at the temperature sensor, not the temperature of the charger. In this manual all temperatures
will be referenced in degrees in Celsius (°C). The user selectable range for battery temperature parameters is -20°C to 60°C. Ensure proper placement of battery
temperature sensor by referencing Step 8 on page 10
Maximum Charge Temperature: The default is 49ºC
The highest temperature of the sensor in which the charger will continue charging. If the temperature sensor measures above the maximum charge temperature, the charger will
enter standby mode, and cease to charge.
Battery Temperature Compensation (Tempco)
Battery temperature compensation is output voltage regulation based on battery temperature variances. Since batteries can see extreme temperature differences it is important
to regulate output voltage with temperature. A battery in a freezing environment should not be charged the same as a battery in a hot environment. The P12 Battery Charger
is set at a baseline of 25°C. Every degree variance from this baseline will result in a voltage variance on all outputs. For every degree above 25°C the charger will reduce all
output voltages by the value defined in Battery Tempco. For every degree below 25°C the charger will increase all output voltages by the value defined in Battery Tempco. For
example, with the default Battery Tempco set to -30mv/°C if the temperature sensor reads 26°C, then all output voltages will be reduced by .03V (30mv). If given the same
Battery Tempco and the temperature sensor reads 24°C, then all output voltages will be increased by .03V (30mv).
CAUTION
Charging batteries below 0°C can be potentially dangerous. Internal battery liquid can freeze and charging a frozen battery could cause serious property or
personal damage. Contact your battery manufacturer for minimum safe charging temperature for your batteries before altering.
CAUTION
Charging batteries above 49°C can be potentially dangerous. Contact your battery manufacturer for the maximum safe charging temperature for your
batteries before altering.
CAUTION
Altering the battery temperature compensation value incorrectly can cause adverse effects on
your battery, by potentially reducing its life. Contact your battery manufacturer to find out the
specific temperature compensation parameters for your batteries.
15
Absorption Timer Counter
The P12 battery charger uses a counter to determine the amount of time a battery bank should remain in Absorb relative to the Maximum Absorb Time. The Absorb timers counter
can be seen in the System Status Screen and also referenced on page 19.
Absorption Parameters and Timers (continued)
Temperature Parameters
Available Timer Modes
When in Float or Standby, the timer will pause.
When in Pre-Float mode the timer for that channel will pause.
When in Bulk mode the remaining time will increase.
When in Absorption mode, the remaining time will decrease.
Once a battery bank’s Absorb timer is reduced to zero, then its output will be changed to Pre-Float. There are
other factors in a battery bank leaving the Absorption stage prior to the Absorb timer running out. Once all battery
banks leave Absorption, all outputs will enter the Float stage, or Rest stage if in Energy Save mode.

6. Press “I Accept” to continue.
7. Using the battery manufacturer’s parameters, input the correct equalization voltage, amperage, and time on the battery bank you would like to equalize.
You may only equalize one battery bank at a time.
Equalization
Definition of Equalization
Equalization is an increased voltage overcharge performed only on flooded lead acid batteries. Once a battery is fully charged equalization increases the voltage and forces
additional charge into the battery to combat negative chemical side effects that can occur in flooded batteries. It is done to compensate for stratification, a
condition where the acid concentration is uneven throughout the battery, and typically higher at the bottom. It is also done to remove sulfate crystals that build up
on the lead plates in flooded batteries.
Prior to Equalization
Contact the manufacturer of your flooded lead acid batteries to confirm the parameters of equalizing your specific batteries. Every battery manufacturer defines different
equalization parameters which are important to understand prior to equalization. All batteries must be fully charged and not under load from any device. The P12 Battery
Charger will not allow equalization to occur if batteries are discharged or powering any device.
Equalization Process
1. Confirm batteries are fully charged by verifying the charger is in Float mode with no active loads.
2. Turn off or disconnect all DC devices that are connected to the batteries. Disconnect the battery banks not being Equalized by removing the fuses at
the battery connection.
NOTE: Equalization parameters vary based on battery size. Confirm parameters for every battery connected to the charger before continuing.
WARNING
Equalization is a user selectable and potentially dangerous charging stage that should not be performed without sufficient knowledge. Personal or property
damage may occur if equalization is performed incorrectly. It is highly recommended that you seek professional guidance before performing equalization.
Equalization causes off gassing of harmful chemicals inside of the battery. Only perform equalization while the batteries are in a well-ventilated area away
from persons and animals.
CAUTION
Equalization may only be performed on flooded (wet) lead acid batteries. Serious personal or property damage may occur if equalization is
performed on any battery type other than flooded lead acid batteries.
NOTE: Equalization will only occur if the battery type is set to “Flooded Lead Acid” (FLA) or “User”. Do not proceed if you are using any other battery type.
See bluesea.com/P12 for details.
4. From any screen simultaneously press and hold the left and right most buttons for 5 seconds.
5. Read and understand the caution screen before proceeding.
3. Confirm use of flooded lead acid batteries.
NOTE: Equalization will not occur if steps 1 and 2 are not met.
