A quality Sony Konion cell encased in safety shrink tubing by Keeppower. Safe and reliable, it provides the necessary energy even in the event of power hungry consumers. A high-current cell originally developed for industry. Best suited for torches with integrated protection electronics (BMS).
Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by qualified personnel.
Incorrect handling or short-circuiting may result in fire or explosion.
Lithium-ion batteries are thermally stable and are not subject to any memory effect.
They work on the basis of lithium and are characterised by a high energy density.
In contrast to the old NiMH/NiCd batteries, the lithium-ion battery discharges much more slowly.
1x Keeppower IMR18650 with 2600 mAh.
When ordering two batteries, a battery box is included free of charge.

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.
