A: Battery Storage
Store batteries at dry, clean, well-ventilated are. Batteries can be stored at 0 35
Ԩ for 6 months
with recharge. Recharge the batteries once if storage period exceeds 6 months.
B: Battery Use
1 Floating charge
Charging parameters
Voltage 2.23 2.30V/cell (25 ) (set point of 2.25V/cell is recommended).
Max. initial current 0.30C
Charging parameters
Voltage 2.23 2.30V/cell (25 ) (set point of 2.25V/cell is recommended).
Max. initial current 0.30C
10
Temp. compensation coefficient -3mV/ . Per cell (from 25 )
Voltage deviation allowed: ±0.02V/cell.
& Note
1). The initial deviations of battery voltages in a group will reduce to a low level after a period of
service, for example, after a half year.
2). Effects of lower or higher voltages
Voltage deviation allowed: ±0.02V/cell.
& Note
1). The initial deviations of battery voltages in a group will reduce to a low level after a period of
service, for example, after a half year.
2). Effects of lower or higher voltages
Higher voltage overcharge
Shorten battery life.
Lower voltage under-charge
Low battery capacity and shorten battery life.
