The car battery is a storage device, which stores energy. This supplies a current at a particular voltage (DC) to the conductive parts of the circuit. The standard car batteries in today’s vehicles are rated at 12 volts. Each battery has six cells which are 2.1 volts each. A car battery is considered fully charged at 12.6 volts. When a battery drops voltage, even by a small amount, it makes a big difference.
For instance, when a battery drops from 12.6 to 12.0 volts, its power drops from 100% to 25%! At 12.4 volts, a car battery is only 75% charged. At 12.2 volts, it’s 50% charged. A car battery is considered charged at 12.4 volts or higher. It is considered discharged when it’s at 12.39 volts or less. The current is heavily dependent on the type of battery and the resistance of the ‘load’.
DC stands for Direct Current and is the term used, in electronics, to indicate a steady positive constant voltage (i.e. not alternating like the electricity in your house).

A battery analysis test will let you know exactly how efficient your battery is and whether or not it is likely to let you down. Modern batteries are built in such a way that they give optimum performance right up to the end of their life. So, when they reach the end, they just stop working with very little warning signs.
Signs to look out for that indicate the vehicle’s battery is reaching the end of its life are:
- The central locking stops working periodically.
- The interior light stops working.
- The media player no longer switches on automatically.
- The media player no longer save the station.
- The sunroof stops opening.
- The boot or tailgate won’t open electronically.
- The stop start function no longer works.
