How to choose Used Car batteries?

1. Difference in service life

The service life of the battery is the most concerned point for consumers when purchasing.

At present, the average service life of lead-acid batteries is about 2 years, and the number of cycles is between 300 and 500 times; the average service life of graphene batteries is about 3 years; lithium batteries have a longer service life, with a cycle number between 700 and 1000 times, and the battery can be replaced every 4 years.

In the past two years, the spontaneous combustion caused by Used Car batteries is mainly caused by Used Electric Car equipped with lithium batteries, especially many small workshops that privately make lithium batteries. Because the density of lithium batteries is large and the heat resistance is poor, if it is overheated, such as in summer or charging for too long, exceeding the load temperature, it may cause spontaneous combustion, especially inferior lithium batteries should be more cautious in safety. Lead-acid batteries are relatively stable and generally rarely spontaneously combust.

2. Difference in safety performance

Degree, it may cause spontaneous combustion, especially inferior lithium batteries should be more cautious in safety. Lead-acid batteries are relatively stable and generally rarely spontaneously combust.

3. Warranty difference

The warranty period of Used Car batteries is an important standard that car owners can refer to when exchanging for other batteries. The warranty periods of lead-acid batteries, graphene batteries, and lithium batteries are very different. Generally, lithium batteries have the longest warranty period.

4. Battery maintenance tips

Plug in the battery plug first, then the power plug; after charging is completed, unplug the power plug first, then the battery plug.

When Used Electric Car are not used for a long time, the battery should be charged normally once a month, and it is strictly forbidden to store it for a long time without power.
