A vehicle battery should last between three and five years under normal circumstances. It’s interesting that since this component is meant to be utilized, the more you use it, the longer it usually lasts. As a result, the shelf life of a battery in a seldom-used car will be short.

The Alternator is the primary element in the charging system. While the engine is operating, the Alternator serves as the primary source of electrical energy and keeps the battery charged.

Connect the meter leads to the battery terminals to test the Alternator; look for 13.5 to 14 volts (while the engine is running, lights and accessories are switched on).

However, with the lights and accessories switched off while engine is running, the battery voltage should range between 14.2-14.7 volts.

Based on the two scenarios indicates the Alternator is charging the battery properly.

Although a brand-new car battery has enough energy to start and operate the vehicle, charging the battery won’t harm it.

The battery will often still start the car if the voltage is higher than 11.8 volts.

In most cases, a car battery cannot be repaired and will need to be replaced when it fails. However, if the battery is not fully dead and is only experiencing a temporary issue, it may be possible to repair it by charging it or replacing the battery cables.

The size of car battery you need will depend on the make and model of your vehicle. It is important to use the correct size battery to ensure proper fit and performance. You can typically find the correct size battery for your vehicle in the owner’s manual or by contacting the manufacturer.

There are several signs that your car battery may be dead, including: a slow crank when starting the car, dim headlights, an engine that does not start, and electrical issues such as power windows and radio not working. Visit the article here to find out about symptoms of a faulty battery.
