21.1 BATTERY
• Instructions for recharging
To recharge the battery a constant voltage charger is needed.
WARNING
Use of other chargers will damage the battery.
General considerations
The recharging of the sealed lead-tin accumulators like the other re chargeable accumulators, is a process that
restores in the battery the energy delivered during the discharge.
Since this process is not efficient in some ways, it is necessary to overcharge the accumulator from 105% to 110%
of the ampere-hour delivered during the discharge.
The quantity of energy necessary for a complete recharge depends: on how heavily the accumulator has been
discharged, on time and method used for the recharge and from the temperature
It is important to observe that the battery is able to deliver all or nearly its rated energy even if it is not overcharged.
However, to get a good life time and maximise number of cycles, the battery must periodically receive the
overcharge specified.
The recharge can be done in different ways. The objective is to make flow the current through the battery in the
opposite direction to that of the discharge. The constant voltage recharge is the convention method to recharge
the lead accumulators.
Constant voltage charger
The constant voltage charger method is the most efficient for the sealed lead-tin accumulators. With this
recharging method no maximum current limit is required on the charger if the charging voltage is kept within the
values specified further on. This characteristic is due to the internal resistance of the battery, which is extremely
low and to the high chemical efficiency during the recharging process.
For a recharge at constant voltage the following data are recommended:
For Cyclic use : from 14.7V to 15V per element at a temperature of 25 °C.
No current limit required.
As buffer battery: from 13.5V to 13.8V per element at a temperature of 25 °C
No current limit required.
