They work on the basis of lithium and are characterized by a high energy density.Technical data for "Xtar 14500 - 800 mAh 3.6 V - 3.7 V protected Li-Ion battery "Notes:For charging lithium ion batteries, a special charger is required, 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 4.2V +-0.05, 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 low charging current, which can be dangerous. Please dispose of them as prescribed by law.
