EFEST IMR18500 - 1000mAh 3,7V Battery

A powerful high-current cell made from a safe chemical compound (lithium manganese). Manganese does not react with lithium, so these cells have high intrinsic safety. Specially designed for battery holders and flashlights.

Notes:

A special charger is required to charge lithium-ion batteries, which charge the batteries through 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 batteries only to about 4.1 volts, as this significantly increases the life or number of charge cycles (possibly up to double). Only lithium-ion chargers should be used for charging. However, the cheap chargers sometimes have the disadvantage that they do not safely switch off after the end of the charging process, but instead continue to charge the batteries with a small charging current, which can be dangerous.

In addition, rechargeable batteries and batteries do not belong in household waste! According to the law, dispose of them in the municipal collection points or in the designated [usually green] containers of the trade.
