Two major reasons affect the service life of 18650 lithium batteries.
Factor 1: The influence of environmental factors at work.
The actual operating environment of the lithium battery will affect the number of battery cycles immediately: the charging temperature of the lithium battery is 0℃~45℃, and the discharging temperature of the lithium battery is -20℃~60℃; during the whole process of charging the lithium battery, 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. Naturally, in addition to operational errors in the operation of lithium batteries, such as short-circuit faults, the service life of lithium batteries is also reduced; for battery charging of lithium batteries, everyone should use a reliable lithium battery charging head to charge the battery. In order to better reduce the specific current and voltage between lithium batteries such as 18650 lithium batteries and the universal charger that are not stable, especially for lithium batteries that have just been charged, 30 minutes should be set aside to wait for the battery charging characteristics to stabilize before application, otherwise it will jeopardize battery performance.
Factor 2: Idle and unused factors are harmful.
If the digital technology and electronic equipment supporting the 18650 lithium battery is not in operation, the 18650 lithium battery should be removed from the instrument and equipment; for long-term storage of lithium batteries, the battery must be charged to 50%~60%, before storage. During the period, the lithium battery should be charged once every 1 to 3 months; for long-term storage of lithium batteries, the temperature range of 10 to 25° must be controlled; Place the rechargeable battery in a natural environment such as microwave heating and high pressure. The common problems in the application of several types of lithium batteries can usually be very good to increase the service life of rechargeable batteries. If the lithium battery is not applied standardly, it will actually cause great damage to the lithium battery, and it is difficult to ensure the service life of the lithium battery.
