How Many Kilometers Before Replacing the Battery?

[PeytonLynn]

Automotive batteries typically last between 3 to 5 years. Below is relevant information about car batteries: 1. Battery: Also known as a storage battery, it is a device that converts chemical energy into electrical energy. Car batteries generally 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 the battery voltage. When using a multimeter for inspection, measure the battery voltage during engine cranking. You can initially use a high-frequency discharge tester or battery tester for measurement. Under a load current not 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 can remain stable for 5 seconds, this indicates over-discharge and requires immediate recharging. If the voltage drops below 9.6 volts and cannot maintain stability within 5 seconds, rapidly declining to 0 volts or near 0 volts, this suggests battery failure and likely requires replacement.
