If you are not the original owner of your car, your battery might not be the original either. It’s a good idea to check your owner’s manual to make sure you are buying the right replacement 158 battery. A number of factors can affect the life of your battery, from leaving your lights on overnight to leaving your car unused for long periods of time, but given a good level of maintenance you won’t have to replace it any more than every five years. Some of the products we stock have greater capacity than others, despite being the same size in terms of dimensions, so it helps to take your time when choosing a new battery. Remember, if you find yourself stuck, be sure to ask a member of the team – we'll be sure to point you in the right direction.
