How Many Years Does a New Car Battery Typically Last?
1 Answers
New car batteries can last 2-3 years. Metrics for measuring battery lifespan: Cycle life and float life. Cycle life refers to the number of times a battery can be recharged; float life refers to the duration a battery can be used while fully charged, simultaneously receiving charging from the engine and supplying power to electrical devices. Factors affecting cycle life: Cycle life is related to the depth of discharge each time. For example, a certain brand's battery can be cycled 500 times if charged after being half discharged each time, but only 300 times if fully discharged before each recharge.
