Your car battery light or charging warning light, which is available on the console of your car, indicates malfunctioning or bad charging of the engine battery. This light comes on whenever the charging system does not charge the battery properly  with a voltage above around  13.4 volts. This warning may be triggered by a number of things, it is important to take proper steps to make sure that you know what the actual issue is before changing any parts.

  • Note: This paper describes a general check of most common car battery vehicle charging systems and some cars can  be tested differently.

The troubleshooting process can be fairly simple  but there are certain issues that only a mechanics  should look at. If the problem appears to be difficult, or if the process of troubleshooting becomes complicated, call a mechanic to come and perform an inspection.

Here’s what you can do when your car’s battery light comes on:

Part 1. React to the battery light

When you first turn on your car with the engine off, the battery light will come on and this is normal. If the battery light stays  on while the engine is running and the vehicle is being driven, this indicates a problem with the cars charging system.

Step 2: Turn off anything that draws power. If the battery light is on, then there is still enough battery left to power the vehicle but possibly not for  long.

If this happens, first turn off anything that draws power from the battery, except for the headlights, if you are driving at night. This includes the air conditioning and heating system, the stereo, any interior lights, and any accessories such as heated seats or heated mirrors. Remove any phone or accessory chargers as well.
