Smart Storage LED (pulsing green):

Smart Storage green LED fades in and out 

when performing the storage recondition procedure to your battery(s) 

Battery Monitor LED (solid green or red)

The Charge Monitor has four green LEDs and one dual color green/red LED. During 

the first phase of charging when the batteries are depleted, the first LED bar lights 

solid red, indicating the batteries being charged are low. 

 As the charging progresses, the first LED bar will transition to green followed by the 

remaining 4 additional LED slight green. 

When all 5 charging LEDs light green it means 

the batteries are fully charged.

This features provides an indication of the 

charging status so that you can quickly 

see the battery charging level.

Troubleshoot LED (solid red)

Depending on the model, up to three red LEDs (bank1, bank2 or bank3) may light 

red, indicating a wiring problem or fault with any of the individual battery(s) connect-

ed to the charger. The Battery Trouble 

Status LED can also indicate if the 

battery that is being charged is under 2.5 

VDC and requires additional testing by 

your local battery dealer before trying to 

charge it.

Fully Automatic Charging Profile

Your Battery Charger is designed to charge all 12 Volts Flooded and AGM Lead Acid 

batteries. 

Note: If you are not sure what kind of battery(s) you have, please consult with the 

manufacturer of the battery(s).

After completing the installation of your charger, making sure there are no wiring or 

connection errors, and the battery(s) connected are > 2.5VDC and can be charged, 

the charger will sequentially perform the following 5-Stage Digital Performance 

Charging Process: Initializing, Fast Charging , Optimizing, Maintaining , Smart

Instructions on Wiring your Charger

The wiring diagrams slightly vary depending on how many banks the charger 

model supports. To find the correct wiring diagram that matches with your battery 

charger model, choose the illustration that has the same number of charger 

output bank cables as your battery charger in hand and wire exactly as shown 

(choose the illustration that matches your application) for proper charger opera-

tion.

Incorrect wiring can result in reverse polarity. In the event this happens, the 

charger has been designed to not fail as a result, however it will cause the 

charger to "internally disconnect" and provide "no output" until the (reverse 

polarity) caused by putting the "Red" + lead on a - negative battery terminal). In 

the event of miswired battery(s), the charger will illuminate a red Battery Trouble 

Status LED for the specific battery requiring attention.

Note: Battery Chargers are designed for any combination of group 24, 27, 29, 30 and 31 batteries. 

Each battery charger DC output cable must be connected to one (1) 12 volts DC battery (even if 

batteries are configured for 24 volts DC or 36 Volt DC trolling motor or system applications). Most 

specifically you do not have to remove series or parallel jumper cables to use your Charger.
Note: Your charger must be connected to the batteries to operate. It will not operate as an individual 

2 volts power supply.

Installation

Each charger cable

 must be 

connected to 1 battery, as 

illustrated. Observe black wire 

to (-) and red wire to (+). 

Do this for each battery.

When connecting to an engine start battery only, connect the battery bank cable 

that is LABELED: "FOR ENGINE BATTERY USE THIS BANK CABLE ONLY".
If there are more charger outputs than batteries, then sets of leads can be 

doubled on the larger battery in your system. Typically these are connected to 

the more drained trolling motor battery
