Lithium-ion battery size 18500 developed for the highest demands and intensive use. Equipped with Seiko (Made in Japan) Protection/*PCB, with short-circuit, overcharge and deep discharge protection, the battery is suitable for many applications where high capacity is crucial.
Developed for the areas of: Torches, LEDs, modelling, industry etc.
Please note the dimensions of the cell before purchasing ! Due to the built-in electronics, the cell is not suitable for every application!
Height and diameter are larger than a standard 18500 cell without *PCB.
Please note that removing or damaging the protective electronics (PCB) can lead to a short circuit, fire or explosion.
Lithium-ion batteries are thermally stable and are not subject to a memory effect.
They work on the basis of lithium and are characterised by a high energy density.

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.
