Jan. 09, 2021

The reason why the life of lithium battery is shortened is 18650 3.7 v Battery Factory to tell everyone.

One of the reasons for the shortened life of lithium batteries: the influence of internal factors of lithium batteries:

18650 Battery 3.7 V 2500mah

18650 Battery 3.7 V 2500mah

1. Side reactions of lithium batteries;

2. Irreversible consumption of active materials in lithium batteries;

3. For large lithium batteries, the battery has a large working current and slow heat dissipation, which can easily damage the battery structure;

4. If safety protection measures are added to the lithium battery, the power provided by the lithium battery is required for maintenance;

The second reason for the shortening of lithium battery life: the influence of working factors

1. The improper working environment of the lithium battery directly affects the length of life: the charging temperature of the lithium battery is 0 ℃ ~ 45 ℃, and the discharge temperature of the lithium battery is -20 ℃ ~ 60 ℃;

2. During the charging and discharging process of the lithium battery, avoid overcharging or overdischarging the lithium battery;

3. When working with lithium batteries, avoid incorrect operation: short circuit;

4. Use a regular matching lithium battery charger to charge the battery.

5. For the newly charged lithium battery, put it aside for half an hour and use it after the charging performance is stable, otherwise it will affect the battery performance. 

The third reason for the shortening of lithium battery life: non-working factors

1. When the digital product matched with the lithium battery does not work, the lithium battery should be removed from the equipment;

2. For long-term storage of lithium batteries, the lithium battery needs to be charged to 97%~98% saturation, and the lithium battery should be charged and discharged once during the storage period of 3 to 6 months;

3. The storage temperature of lithium batteries should be controlled in a space of 10°~25°;

4. Do not knock, acupuncture, step on, modify, or expose the battery to the sun, and do not place the battery in a microwave, high-voltage environment, etc.
