How long do car batteries last?
Whilst there is no specific answer to this question as there are a number of aspects that can affect the batteries lifespan, we do know from industry experience that, in general car batteries should last between 3 and 5 years typically.
Over time, batteries will gradually weaken until the power they supply is no longer enough to start a car’s engine. If you use your car infrequently or for short journey’s, then the battery may start to deteriorate early as it is not getting fully recharged. Climate is also a factor; the chemical reaction within the battery is facilitated by heat which increases the rate of battery deterioration therefore batteries will last longer in cooler climates than in hotter climates.
Warning signs of a battery fault:
If the battery or engine warning light is illuminated on your dashboard this indicates that there is a problem with the battery; usually low voltage which triggers the cars ECU (engine control unit). It is advised that the battery is tested as soon as possible. Other tell-tale signs include trouble starting the car, the engine becomes slow to start when the key is turned or electrical issues such as dimmed lights.
There are a number of factors to consider when replacing your battery including the size, type and terminal configuration to name a few.
