The voltages in the above table apply to a single cell. The data may deviate depending on manufacturer
(observe manufacturer's information!).
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 rechargeable 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 precedence over the information in the above
table.
Important!
•
Never charge battery packs made up of different cells (or cells from different manufacturers).
•
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.
