Car battery bad voltage

When a battery is completely charged, its voltage should be at 12.6 volts or above. But this rule is applicable when the engine is turned off. If you measure the voltage of your car battery shortly after you had the engine running, it is likely that you’ll get a higher and wrong reading.

If your car’s performance isn’t up to the mark, then a low voltage battery may be the reason for it. A car battery voltage has to be of a certain level and you need to check it on a regular basis to be prepared in case your battery needs to be replaced. Here is all you need to know about the voltage of your car battery:

The first thing to do is measure the voltage of the battery. It is important to note that the voltage of the battery can’t tell us for sure if the battery is good or bad, but it can tell us if the battery is low on voltage or not. Ultimately we will need more information than just the battery voltage to tell us if the battery is bad.
