A good car battery should last for between five and seven years on average. However, this depends upon a number of factors. For example, if you do not use your car for a long period of time, or if you tend to use your car for shorter journeys, this can affect the lifespan of the battery.
One of the problems with batteries is that you often don’t get any warning signs when a battery is on its last legs. For that reason, we recommend getting it checked over regularly by a qualified technician to highlight any problems before your battery fails on you.
