CHARGING INSTRUCTIONSHandles: All part numbers include lifting handles except the
Ratings: Capacity ratings are stated at 77F (25 C) to 1.75 volts per cell.
Initial charge or recharge: 2.37 to 2.40 volts per cell at 25 C (77 F).
Float charge: 2.23 volts per cell at 25 C (77 F).
Equalize charge: 2.40 volts per cell at 25 C (77 F).
Temperature compensation = ±3.75 mV. per cell per degree C [Reference to 25 C (77 F)]. This is for battery temperature (not ambient temperature) and is useful for battery temperatures from O C (32 F) to 40 C (104 F). Contact Concorde Battery Corporation for temperatures that exceed this range.
