How do I know if my BMW car battery needs replacing?

On average, your BMW’s battery will probably need replacing once every four or five years, although some of our NAPA batteries offer a longer lifespan. As for knowing when the time for a replacement has come, there are some tell-tale signs that your battery may be on its last legs:

• Your dashboard warning lights are telling you something is wrong. If you can see the battery or engine warning lights lit up, it’s time to get your battery tested.
• You’re struggling to start your car. Batteries become less effective over time and one of the most obvious signs of decreased effectiveness lies in your car engine being slow to start or not starting at all.
• You’re noticing electrical issues, such as dimming light, unresponsive electric windows or problems with the heating or AC.

How can I get my BMW battery tested?

If you wish, you can test your BMW car battery at home with the help of a multimeter. That, however, requires you to have the right kit available, not to mention the desire to do the testing yourself! The quicker, easier and more reliable option is to get it checked with us, free of charge.

Our free battery-testing service can help to spot any minor issues with your car battery before they become a bigger problem. Our testing checks your battery’s voltage, start capacity and general condition to make sure that it’s working as it should. If we do come across any issues, we can arrange for your BMW’s battery replacement right away – it’s a hassle-free process that takes a matter of minutes.

We’d recommend getting your BMW’s car battery tested twice a year for complete peace of mind.

What battery do I need for my BMW?

The two easiest ways to find out what battery is best for your BMW are to check your owner’s manual or to type your car’s registration into our battery search tool at the top of the page. We supply a full range of high-quality NAPA batteries – the right one for your BMW will likely depend on your budget and how you use your car.

If you need a hand choosing the right BMW car battery, our battery technicians can offer expert advice on the four compatible battery types that we sell.

NAPA AGM

NAPA absorbed glass mat (AGM) batteries are sealed lead-acid batteries ideal for use with micro-hybrid BMW models. NAPA AGM batteries have been manufactured with stop-start technology and other fuel-reducing technologies such as brake energy regeneration.

NAPA AGM batteries feature a fibreglass mat which absorbs any spilt sulphuric acid, therefore preventing any leakage. They also offer increased lifespan and fuel efficiency and lower CO2 emissions compared to NAPA AFB batteries.

NAPA AFB

NAPA advanced flooded batteries (AFB), otherwise known as enhanced cycle mat (ECM) or enhanced flooded batteries (ECB), are an evolution of the standard wet flooded battery.

AFB technology offers increased cyclic performance and is built for vehicles that operate stop-start technology.

NAPA PLUS

The best choice for vehicles that operate additional electrical features including satellite navigation and media players, NAPA PLUS batteries offer 30% extra power for heavy-duty performance.

The NAPA PLUS battery uses labyrinth technology to enable the flow of water back into the battery to maintain fluid levels and increase shelf life.

NAPA

NAPA’s standard flooded lead-acid battery can be fitted to most vehicles. Utilising calcium/calcium technology for longer life, reduced water loss and better temperature resistance while in operation, it’s an ideal battery for most engines, including diesel models.

What should I expect to pay for a BMW battery replacement?

We can’t tell you right here exactly what your BMW battery replacement cost will be – that depends on your needs and the type of battery for which you end up going.

If you’re looking for an idea of how much your new BMW car battery will cost, you can enter your car’s registration into our battery search tool at the top of the page. There you’ll find prices for our battery options, which include fitting and disposal.

We’re proud to offer unbeatable prices on our BMW battery range, starting at £61 through our price promise scheme. We also offer flexible payment options so that you can spread out the cost of your purchase to suit your budget.

How long will my new BMW battery last?

As a general rule, you can expect your car battery to last for somewhere between four and five years but lifespan depends on a number of factors like your BMW model, how you use your car and the conditions in which your car battery is exposed.

It’s not easy to predict when you’ll need a BMW battery replacement but all of our NAPA batteries offer at least a four-year guarantee, with others extending to five years.

• NAPA battery range: four-year guarantee
• NAPA Plus: five-year guarantee
• NAPA AFB and AGM ranges: five-year guarantee
