How to Charge the Li-ion Batteries

Lithium-ion batteries are used as a source of energy in laptops and cell phones, video cameras and other consumer electronics (e.g. Manker Rambler flashlight). They are demanding to the voltage at the time of charging, and therefore should be charged by special charges.

Do not allow a complete discharge of batteries. They do not tolerate it and are easily damaged. It is recommended to maintain the charge level of at least 75% of the total. Lithium-ion batteries are charged on a "constant current / constant voltage". Unlike conventional batteries, lithium-ion requires a higher voltage per cell (about 3.6 V). If, for example, lead-acid batteries can be recharged slowly after full charge, the lithium ion devoid of such ability.

Ensure that the battery charging conditions. Lithium-ion batteries can operate at temperatures from 0 to + 60 ° C. In the negative temperature conditions, the battery stops charging them. A distinctive feature of the lithium-ion batteries (e.g. the Xtar 18650 battery) is a very high sensitivity to increased stress at the time of charging. There are times when the batteries from this light. To avoid such incidents, modern lithium-ion battery is inserted into a special electronic board which disconnects the battery if it is overheating. Another way to avoid overheating the battery is the use of "smart" chargers. Most modern chargers can determine the time of the full battery charge current on and off independently.

Connect the battery to the charger, and it, in turn, connect to the network. Some chargers allow you to choose the maximum current. For example, low-power batteries can be recharged current of 500 mA, and more powerful batteries - current of 1000 mA. This makes it possible to reduce the charging time. After charging, disconnect the battery from the charger. If the battery is not used for a long time, it is better to charge it at 60-70 percent.
