What Does an 8-Year Warranty on Electric Vehicle Batteries Mean?
1 Answers
If the battery pack experiences quality issues or severe degradation within eight years, the automaker will replace it with a new one for free. Below is relevant information about automotive batteries: 1. Battery: Also known as a storage battery, it is a device that converts chemical energy into electrical energy. Automotive batteries typically refer to lead-acid batteries, which are primarily made of lead and its oxides with sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, largely depending on vehicle usage conditions. 2. Battery Replacement: If the battery is dead, it's recommended to first measure its voltage. When using a multimeter, check the battery voltage during engine cranking. You can initially measure it with a high-frequency discharge tester or battery tester - under a load current of no less than 110 amps, the minimum voltage should not fall below 9.6 volts and must remain stable for 5 seconds. If the voltage is below 9.6 volts but remains stable for 5 seconds, it indicates over-discharge and requires prompt recharging. If the voltage drops below 9.6 volts and cannot stabilize within 5 seconds, rapidly declining to 0 volts or near 0 volts, this suggests battery failure and likely requires replacement.
