Battery Charging:
All batteries must be adequately vented during charging to avoid accumulation of explosive
hydrogen gasses. Never install or charge in a sealed container or room.
The following charging voltages are recommended for maximum battery life.
Charging Phase 2 Volt Battery 6 Volt Battery 12 Volt Battery
Bulk/Absorb 2.37v - 2.40v 7.10v - 7.20v 14.2v - 14.4v
Float 2.20v - 2.23v 6.60v - 6.70v 13.20v - 13.40v
Charge voltage should be adjusted if battery temperature varies by more than 10°F from 77°F.
Conditioning/Equalizing Charge: 15.5 volts for 8 hours
Conditioning/equalizing should only be done when the battery is showing symptoms of capacity loss. If
conditioning/equalizing is necessary, first go through the normal charge cycle. Once the battery is as fully charged
as possible, start the conditioning/equalizing charge.
For maximum battery life, a battery must be recharged to 100% capacity. Recharging to less than 100% may
result in premature battery failure. Batteries are not covered under warranty if they are not recharged properly.
An electronic copy of the Material Safety Data Sheet (MSDS) for the battery is included on the CD provided with
your manual.
Knowing when to recharge:
For maximum battery life in cycling applications, do not discharge the battery bank below 50%. Discharging the
bank repeatedly to 100% will shorten the battery life. The open circuit voltages listed below correspond to the
various states of charge:
State of Charge 2 Volt Battery 6 Volt Battery 12 Volt Battery
100% 2.16V or more 6.50V or more 12.8V or more
75% 2.08V 6.25V 12.5V
50% 2.03V 6.10V 12.2V
25% 1.98V 5.95V 11.9V
0% 1.93V or less 5.8V or less 11.6V or less
