7. Usable Rechargeable Battery Types
Rechargeable battery type
Rated voltage (V/cell)
Max. charging voltage (V/cell)
Voltage for storage (V/cell)
Charging current for quick
charge
Min. voltage after discharge
(V/cell)
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 fire and explosion from the recharge-
able battery!
Further notes on the max. charging current and the cell number/voltage can be taken
from the data sheets or the labels of the rechargeable batteries; these data take prec-
edence over the information in the above table.
Important!
• Never charge battery packs made up of different cells (or cells from different manu-
facturers).
• Never charge non-rechargeable batteries.
• Never charge rechargeable batteries not listed in the above table.
• Never charge rechargeable batteries with integrated electronics.
• Never charge rechargeable batteries that are still connected to other devices (e.g.
a speed controller).
• Never charge any damaged or bloated rechargeable batteries.
