The voltages in the above table apply to a single cell.
The max. charging and discharging currents are indicated with the capacity value "C".
A charging current of 1C corresponds to the capacity value imprinted on the battery
(e.g. indicated battery capacity 1000 mAh, max. charging current 1000 mA = 1 A).
Also observe the correct voltage setting for multi-cell battery packs. For example, the
individual cells in a two-cell battery pack may be switched in parallel or in series.
If the maximum permissible charging current for the rechargeable battery is exceeded
or a wrong cell number/voltage setting is chosen, there is a danger of destroying the
rechargeablebattery.Therealsoisadangerofreandexplosionfromtherecharge-
