Frequently Asked Questions About Racing Batteries

What’s the difference between an XS Power 12 volt battery and an XS Power 16 volt battery for racing?

An XS Power 12 volt battery is the common choice for most circle track and street/strip builds, giving you straightforward compatibility with standard starters and electronics. An XS Power 16 volt battery is typically used in racing to help the starter hit harder and to keep voltage up under heavy load, useful when you’re chasing quicker, more consistent starts and stable system voltage. Either way, choosing the right XS Power battery comes down to your car’s electrical system and what your components are designed to handle. 

Do I need a specific XS Power battery charger for 16V racing batteries?

Yes, if you’re running 16V, use an XS Power battery charger designed for 16V charging. XS Power’s IntelliCharger models are built for performance batteries and are available in versions that support 16V (and some that support 12/14/16V), using multi-stage charging to charge quickly and help avoid overcharging. 

Why do racers pair an XS Power starting battery with an XS Power IntelliCharger? 

Because a starting battery is only as good as its state of charge. Racers pair an XS Power starting battery with an XS Power IntelliCharger to keep the battery ready for hot restarts, reduce downtime between heats, and maintain strong voltage for ignition/EFI and other electronics, especially when the car sits between sessions.
