Thread: Best Trolling Motor Batteries?

When it comes to batteries just don't scrimp on the $ as I have done that in past and cost me more in long run

Whats a set of those run?

Thanks for posting that info BRM. Learned something today. Everyone of us who leave our chargers hooked up all the time need to read that little blurb under temp adjustment. Talking about equalizing each cell with automatic chargers. Hopefully someone can copy that section and post it. Good info.

Here you go

CHARGING INSTRUCTIONS:
Following is the charging recommendation and charging profile using 2 stage chargers for US Battery deep cycle products.
*Equalization and float charge modes are not considered to be one of the stages in a charging profile.

1. Bulk Charge Constant current @-1 0% of C/20 Ah in amps to 2.45+/-0.05 volts per cell
(e.g. 7.35 volts +/-0.15 volts per 6 volt battery)

2. Absorption Charge Constant voltage (2.45+/-0.05 vpc) to 3% of C/20 Ah in amps then hold for 2-3 hours and terminate charge
Charge termination can be by maximum time (2-4 hr) or dV/dt (4 mv/cell per hour)
• (Optional Float Charge) Constant voltage 2.17 vpc (6.51 volts per 6 volt battery) for unlimited time
• Equalization Charge Constant voltage (2.55+/-0.05 vpc) extended for 1-3 hours after normal charge cycle (repeat every 30 days)

Notes: Charge time from full discharge is 9-12 hours.
Absorption charge time is determined by the battery but will usually be +/- 3 hours at 2.45 volts per cell.
Float time is unlimited at 2.17 volts per cell.
Specific gravity at full charge is 1.270 minimum

Battery temperature adjustment: reduce the voltage by 0.028 Volts per cell for every 10*F above 80*F, increase by the same amount for temperatures below 80*•F.

Deep cycle batteries need to be equalized periodically. Equalizing is an extended, low current charge performed after the normal charge cycle.
This extra charge helps keep all cells in balance. Actively used batteries should be equalized once per month.
Manually timed chargers should have the charge time extended approximately 3 hours.
Automatically controlled chargers should be unplugged and reconnected after completing a charge.
