How We Rated

Although car batteries can last many years, they’ll eventually require replacement when they become faulty. Therefore, as we own multiple cars, we replace car batteries far more often than the average motorist, which means that we have experience with a variety of batteries in terms of their size and brand.

With regards to our testing, we tested batteries from a variety of brands and replaced multiple-sized batteries.

As you can see below, we recently replaced an older Varta battery with a DriveTec alternative and the difference was instant because the older battery couldn’t hold a charge for longer than a few days. However, during our testing, as well as the performance of the batteries, we also analyse their quality in terms of their carry handles and terminals.

Some of the factors that we took into consideration included their brand reputation, capacity, service life, carry handle, terminals, warranty and value for money.

Conclusion

All of the recommended car batteries above are suitable for all budgets and are produced by reputable UK brands. However, before buying any of the recommendations, it’s advised that you check the specification matches your current battery. You may also want to ensure that the current battery is actually faulty. One of the easiest ways of doing this would be to use a battery charger but if you have a battery tester available, that would be the best option.
