How long is the life of lead-acid batteries for electric vehicles? How to maintain?

At present, there are two kinds of electric vehicle batteries on the market: lead-acid batteries and lithium batteries. The life of lead-acid battery is defined as the battery capacity decays to 30% of the original capacity. Generally, it needs to be fully charged and discharged for about 300 times, with a service life of about one and a half years. If the riding distance is short, it can be used for about three years. Lithium battery has strict charging times, generally about 1000-1200 times, with a service life of 3-5 years.

The cost of batteries is generally between 300 and 1000, but even so, frequent replacement will also bring a big test to household expenditure. In order to prolong the service life of the battery, the following two points should be kept in mind:

1. Do not harm the battery: there are many behaviors harmful to the battery of electric vehicles, such as over discharge, sudden braking, excessive load, serial use of new and old batteries, rapid charging, overcharging, etc., This will affect the service life of the battery and shorten its service life.

2. Regular maintenance: regularly check the battery shell of electric vehicles to see if there are deformation, damage, scratches and other problems. If yes, go to the maintenance site in time for maintenance and thorough inspection. If the terminal is found to have corrosion, it should also be handled in time to avoid leakage.
