Inexpensive 18650 battery in the usual Keeppower quality. By using an industry standard cell from a premium manufacturer based in Asia, the price has been corrected significantly downwards. High quality rechargeable Lithium Ion battery with long life and high cycle stability. Protection/PCB with short circuit, overcharge and deep discharge protection. Seiko (Made in Japan). Designed for torches, LEDs, battery packs, etc.
ATTENTION: 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. Not suitable for e-cigarette or shisha.
1x lithium ion battery 18650 Keeppower P1826C.
Please note that removing or damaging the protective electronics (PCB) may result in a short circuit, fire 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.
