Batteries ordered in pairs (quantity 2) are delivered in a battery storage box.

* The nominal capacity of a rechargeable battery indicates the amount of energy it can store under ideal laboratory conditions. This value is measured at a constant temperature and under specified conditions in order to provide a reliable reference for the performance of the battery. Measurements with standard household devices (e.g. USB measuring devices, chargers with an analyser function) often show lower values, as these operate under different conditions and cannot achieve the manufacturer’s laboratory conditions.

** The minimum capacity is the minimum value that a battery must reliably deliver. It is guaranteed by the manufacturer, even if there are small deviations during production.

¹PCB/BMS: A PCB (Protection Circuit Board) is a protective circuit that protects individual lithium-ion cells from overcharging, deep discharge, short circuit and overcurrent.
A BMS (Battery Management System) is used in battery packs with multiple cells and also handles cell balancing, temperature monitoring and communication with devices.

Technical Data

Notes:

Charging lithium-ion batteries requires a special charger that charges the batteries using a special charging process. (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or number of charging cycles (possibly up to double). Only lithium-ion chargers may be used for charging. However, cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a low charging current, which can be dangerous.

Furthermore, rechargeable batteries and batteries do not belong in household waste! Please dispose of them as prescribed by law in the municipal collection centres or in the [usually green] containers provided for this purpose by retailers.
