How Many Years Can a Pure Electric Vehicle Battery Last?

[Marissa]

The battery can last for about 6-8 years without issues. Here is some relevant information about the battery: 1. Battery: The battery, also known as a storage battery, is a device that converts chemical energy into electrical energy. It refers to a lead-acid battery, which is primarily made of lead and its oxides, with sulfuric acid solution as the electrolyte. The normal lifespan of a car battery ranges from 1 to 8 years, depending largely on the vehicle's usage. 2. Battery Replacement: If the battery is dead, it is recommended to first measure the battery voltage. If using a multimeter, measure the battery voltage during engine cranking. You can initially use a high-frequency discharger or a battery tester to measure it. Under a load current of no less than 110 amps, the minimum voltage should not be lower than 9.6 volts and should remain stable for 5 seconds. If the voltage is below 9.6 volts but can remain stable for 5 seconds, it indicates over-discharge, and the battery should be recharged promptly. If the voltage is below 9.6 volts and cannot remain stable within 5 seconds, dropping rapidly to 0 volts or close to 0 volts, it suggests a battery fault, and replacement may be necessary.
