Regularly checking or replacing your car's battery can help keep your BMW running smoothly for years to come.

But when should you change your battery - and how do you know if it's dying?

Experts recommend complete replacement every 4 years, and you should have it checked if you notice any of the following signs your battery might be dying:

• Battery warning light illuminates on the dashboard
• Electrical components don't work or aren't functioning well
• The engine takes longer to start
