Should I charge my car battery or replace it?

Over time, a battery loses its capacity or ability to hold charge. To avoid this situation, a battery should be replaced before its capacity drops to the critical level. On average, a car battery lasts from 5 to 7 years. The battery lasts longer if the vehicle is driven daily and the battery is kept fully charged.

Similarly, you may ask, is it better to charge a car battery or buy a new one?

If it's just been discharged (e.g. by leaving the headlights on while the car's parked), charging the battery is the best option. If the battery is dead, you'll have to replace it. A repair shop can test the battery to see if it's still usable.

Additionally, how do I know when my car battery needs replacing? Here are seven telltale signs that your car battery is dying:

  1. A slow starting engine. Over time, the components inside your battery will wear out and become less effective.
  2. Dim lights and electrical issues.
  3. The check engine light is on.
  4. A bad smell.
  5. Corroded connectors.
  6. A misshapen battery case.
  7. An old battery.

Likewise, people ask, will a completely dead battery charge?

A car battery is considered discharged when the voltage drops below 12 volts. While your vehicle's alternator can keep a healthy battery charged, it was never designed to completely recharge a dead car battery. Most of the time, you don't even have to remove the battery from your vehicle.

How long do I need to drive my car to charge the battery?

The longer the battery has been dead, the longer it will take to fully recharge it. However, by driving for at least a half an hour at 1,000 RPM's, you should charge your battery enough that you will be able to restart the vehicle once you turn it off.
