12v 18650 battery pack

　　Two reasons affect the service life of 18650 lithium battery.

　　Factor one: the influence of environmental factors in the work.

　　The poor operating environment of lithium batteries directly affects the number of battery cycles: the charging temperature of lithium batteries is 0°C~45°C, and the discharge temperature of lithium batteries is -20°C~60°C; during the charging process of lithium batteries, do not overcharge , Power loss and other conditions; whether it is over-discharge or over-charge, it will cause inevitable harm to the quality of lithium batteries. Of course, in addition to operating errors in the operation of lithium batteries, such as short-circuit failures are also the reason for the shortened service life of lithium batteries; for charging lithium batteries, everyone should use reliable lithium battery chargers to charge batteries. In order to reduce the actual current and voltage between the 18650 lithium battery and other lithium batteries and the universal charger does not reach a stable value, especially for the lithium battery that has just been charged, you should wait for 30 minutes for the charging performance of the battery to stabilize before charging. Use, otherwise it will affect battery performance.

　　Factor 2: Idle and unused factors are harmful.

　　If the digital electronic equipment supporting the 18650 lithium battery is not working, then the 18650 lithium battery should be removed from the equipment product; for long-term storage of the lithium battery, it needs to be charged to 50%~60%, and then stored During the period, lithium batteries should be charged once every 1-3 months; for long-term storage of lithium batteries, the temperature range of 10-25° must be controlled; Place the rechargeable battery in an environment such as microwave heating and high pressure. The common problems in the application of the above-mentioned types of lithium batteries can generally increase the service life of the rechargeable battery very well. If the lithium battery is not used properly, it will actually cause great damage to the lithium battery, and it will be difficult to ensure the service life of the lithium battery.
