Charging
The most common form of charging for stationary
batteries is modified constant voltage,usually with current limitation
to C/5 or C/10. The battery permanently connected to the charger
which applies a constant voltage across the battery terminals.
Recommended charging voltage
The following per-cell charge voltage are recommended
| cell type |
floating charge |
equalizing charge |
| KPX |
1.38-1.40 |
1.46-1.48 |
| KPH |
1.42-1.45 |
1.55-1.60 |
| KPM |
1.42-1.45 |
1.55-1.60 |
| KPL |
1.48-1.50 |
1.55-1.60 |
Initial charging
The whole charge should perferable be carried out at constant current.
The charging time is inversely proportional to the current which
is set by the current limit of the charging equipment.
Recommended rates for the first charging:
0.2C5A for 10 hours
0.1C5A for 20 hours
