Due to high quality standards and high quality components, Keeppower batteries have enjoyed great popularity for a long time, not only among torch enthusiasts. The base cell of the 3500 mAh battery is a quality industrial cell from Panasonic NCR18650GA.
Equipped with Seiko (Made in Japan). Protection/PCB with short circuit, overcharge and deep discharge protection, this is suitable for just about all torches. The Keeppower 18650 batteries are especially recommended for torches, LEDs and mech. battery carriers.
Please note the dimensions of the cell before buying! Due to the built-in electronics, the cell is not suitable for every application!
Height and diameter are larger than a standard 18650 cell without PCB.
Please note that removing or damaging the protective electronics (PCB) may result in a short circuit, fire development or explosion.
Lithium-ion batteries are thermally stable and are not subject to memory effect.
They work on the basis of lithium and are characterised by a high energy density.

Notes:
A special charger is required for charging lithium ion batteries, which charges the batteries according to a special charging procedure. (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 the number of charging cycles (possibly up to double). Only lithium ion chargers may be used for charging. However, the 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 small 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 at the municipal collection points or in the [usually green] containers provided by retailers.
