For the charging of lithium-ion batteries, a special charger is required, which charges the batteries according to a special charging procedure. (CCCV = constand current, constant voltage.) The batteries must not be charged via a voltage of 4.35 volts, as there is a risk of fire or explosion. It is advantageous to charge the batteries only up to approx. 4.2 volts, since this significantly increases the service life or number of charging cycles (possibly up to a doubling). Only lithium ion chargers may be used for charging.
However, the cheap chargers sometimes have the disadvantage that they do not switch off safely after the end of the charging process, but the rechargeable batteries with a small charging current, which can be dangerous. Batteries and batteries are not included in household waste! Please dispose of these as prescribed by law in the municipal collection points or in the intended [mostly green] containers of the trade.
Note: Lithium cells may only be operated with protective electronics! Safety instructions: Please note that lithium cells may only be used by qualified persons. Incorrect handling or short-circuiting can lead to fire development or explosion. Other features: Lithium-ion batteries are thermally stable and are not subject to any memory effect. They are based on lithium and have a high energy density.
