How often should I replace my BMW 1 Series battery?

I have had my BMW 1 Series for 3 years now and am wondering when I should consider replacing the battery. It seems to be working fine so far, but I don't want to wait until it completely dies on me. Can someone give me some advice on when I should start thinking about getting a new battery?

It is recommended to replace your battery every 4-5 years. However, it is best to periodically check its voltage and performance to see if it needs to be replaced earlier. It's always better to be safe than sorry when it comes to your car's battery.

In general, a battery's lifespan can vary depending on driving habits and climate. If you live in a colder climate, it is best to replace your battery every 3-4 years to avoid any issues during the winter months. If you drive frequently or in stop-and-go traffic, your battery may also wear out faster.

It's always a good idea to get your battery checked during routine maintenance visits. A mechanic can run a battery test to see how much life it has left and advise you on when it should be replaced. Don't wait until you're stranded with a dead battery to get it checked!
