Working in high temperature and humidity environment, lithium batteries are prone to performance degradation, short circuit and other issues, so what are the precautions for the use and maintenance of lithium batteries? Next, let's take a look at it.

Charging section

After we get a lithium battery, don't rush to recharge it. We must read the instructions carefully before using it.

1. Charging with higher than recommended current may cause problems in charge-discharge performance, mechanical performance and safety performance of batteries, and may lead to heating or leakage, which will greatly reduce the service life of batteries.

2. The charging voltage is higher than the recommended voltage, which may cause the overcharging of the core, generally because of the wrong charging method of the user.

3. Charging temperature. Firstly, the charging temperature here refers to the ambient temperature during the charging process rather than the temperature generated during the charging process. When the surface temperature of the battery is abnormal, the charging should be terminated immediately.

4. Requirements: Charging must be cared for by a special person, and choose a spacious place without inflammables. Remember!!!

Discharge article

1. The discharge current shall not exceed the discharge current specified by the battery. Excessive current discharging will result in drastic capacity reduction and battery overdischarge expansion.

2. Discharge temperature: Batteries must be discharged at the operating temperature specified in the manual. When the surface temperature of the battery exceeds 60 degrees, it should be suspended until the battery is cooled to room temperature.

3. Overdischarge: Overdischarge can cause devastating damage to the battery, so the voltage of the single battery should not be lower than 3.7V when discharging.

Battery Storage Paper

Batteries should be stored in a cool environment. When batteries are stored for a long time, it is recommended that they be stored in a non-corrosive gas environment with a temperature of 10-25. Batteries are charged and discharged every 3 months during long-term storage to maintain battery activity and ensure that the voltage of each cell is within 3.85V.

If a battery is not intended to be used in a short time, remember not to charge it before saving it, so it is very easy for the battery to bulge during storage. The storage method is that the storage voltage is about 3.8V.

Treatment of ignition

When the battery is on fire, first cut off the power supply of the equipment; quickly observe the storage location of asbestos gloves and asbestos blankets nearby; remove the lithium batteries from the charging rack with asbestos gloves or tongs and place them in the ground or fire bucket. Cover the ground with asbestos blankets for lithium battery flames. Fire-fighting sand buries asbestos blankets to isolate air and suffocate them.

Avoid

When dry powder is used to extinguish chemical fire of solid metals, a large amount of dust is needed to cover the fire, and the equipment is corroded and the space is polluted. Carbon dioxide does not pollute the space and corrode the machine, but it can only inhibit the fire instantaneously. It needs to be used with sandstone and asbestos blanket.
