With the discharge process, the specific gravity of electrolyte changes greatly (it is impossible to
measure, only calculate the results), so the open circuit voltage is measured. The approximate
residual capacity can be calculated .
The figure below shows the relationship between the open clamp voltage and the state of charge (state
of charge – SOC
).
Recharge
Generally speaking, lead sulfate will be produced in the battery negative plate, this is called "sulfate"
after they were stored for a long time.Because lead sulfate is an insulator, it will influence the
performance of the charge. therefore it is recommended that the battery is stored in a dry, cool the
environment .
Temperature Time before rechargment
-1- <20°C 9 months
-2- 20°C ̴ 30°C 6 months
-3- >30°C ̴ 40°C 3 months
Recharge management:
-1- Constant voltage (2,23 ̴ 2,27)V/Cell, current limit 0.25C10 (2 ̴ 3) days.
-2- Constant voltage (2,30 ̴ 2,40)V/Cell, current limit 0,25C10 (10 ̴ 16) hours.
-3- 0,1C1 constant current charge for 8h or 0,05C10 constant current charge.
