Discharge
(Maintenance Rules For Valve-Regulated Sealed Lead Acid Battery
NP Series)
1. Temperature of battery undergoing discharge ranges between -15℃~+50℃.
2. Continuing discharge current is required to lower than 3CA (
H is required to lower than 6CA).

1.70V/single cell
|
|
Between 0.5CA and 1.0CA
|
1.55V/single cell
|
|
Above 1.0CA
|

4. Charge at once after discharge. Over-charge also demands immediate
charge.
