How long should car battery last

The lifetime of a car battery is determined by how often the alternator charges the battery.

how do i know when my car needs a new battery?

there is a simple test that will help you figure this out on your own. remove the battery cable on the positive terminal and touch the cable on metal with one hand, while using your other hand to ground it to some metal somewhere in the engine bay. then verify voltage with a voltmeter by stripping insulation from around some wire and touching each probe tip to eithers of he two terminals that connect to each end of your car battery. you'll get 12 volts if everything checks out – alternator is still good, cables are good, and no corrosion has built up which can keep an electrical charge from flowing freely through them.
it's really important for modern cars not to overcharge their batteries because they need sensitive electronics inside them like computers

how often does a car battery need to be replaced?

once every 3-5 years.
car batteries usually need to be replaced when they can't hold a charge or when they disturbingly lose power when you turn the headlights on. the only way to really know whether you need a new battery is by diagnosing it with an electrician using a diagnostic machine for cars, but most people simply rely on the “3-5 year” rule of thumb that many mechanics use as well.

what is the average life of a car battery?

car batteries typically last three to five years in service.

can a car battery last 10 years?

the life of the battery will depend on the quality, how it is taken care of, and where you live. but generally, most batteries last about five years.

there are many factors that determine the durability of a car battery. age is one factor that affects its lifespan; typically a battery lasts for four to eight years in an average environment with frequent use. a newer vehicle would be expected to have longer-lasting batteries than older ones because modern cars require more power than their predecessors did when they were manufactured almost 30 years ago.
