which racing battery?


Over the years, Racing Batteries have built up a wealth of knowledge about what battery starts what kind of engine, and how to select and best look after the battery to give you years of reliable service - see our FAQs for more details. This allows us to select the lightest battery for your needs, whether it's for racing, track day or everyday use.

If your vehicle is not listed in the main menus (and we can't list them all!) then this battery lookup table gives you an idea of which model you will need. You might be able to use a smaller & lighter battery than this if your vehicle is used only on track (road vehicles give their batteries a harder time). However, you may need a larger battery if your engine is highly tuned, if you need to start in cold weather, or if you're running total loss ignition. You may also need a bigger battery if you have a Ducati or BMW motorcycle fitted with the stock ECU.

Remember, though Racing Batteries have all the starting power you need, they can have less capacity than conventional lead acid units - but this is usually only an issue if you are running total loss.

If you contact us with your vehicle details (usage, engine, state of tune) we may be able to more accurately match a lighter battery to your requirements.
