User Manual
Finish charge time is typically 2-4 hours.
Float time is unlimited at 2.23 volts per cell.
Two-Stage Charger (Constant Current-Constant Voltage)*
Following is the chargeing recommendations and charging profile using 2 stage* chargers for US
AGM deep cycle products.
*
Equalization and float charge modes are not considered to be one of the stages in a charge profile.
1. Bulk Charge Constant current @ maximum bulk charge 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 minimum absorption charge then hold for 2-3
hours and terminate charge.
• (Optional Float Charge) Constant voltage 2.23+/-0.03 vpc (6.70 volts per 6 volt battery) for unlimited time
• Equalization Charge Constant voltage (2.45+/-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.
Finish charge time is typically 2-4 hours.
Float time is unlimited at 2.23 volts per cell.
