Whatever you’re driving, it all starts with your vehicle battery. It cranks the engine and powers your lights and other electrical accessories, so you want to make sure that it is in optimal working condition.

In this section we provide some general advice on maintaining and caring for your marine, and deep cycle battery units.

Preventative Maintenance

A range of factors can impact the performance of your vehicle battery. In order to make sure that your car battery stays in optimal condition, you should have it regularly tested at your nearest SuperCharge location.


Having your car battery tested on a regular basis is essential. Normal wear and tear can take a toll, and some problems can only be discovered by proper inspection.

Some of the tests we run at SuperCharge include checking for surface charge, measuring the state-of-charge, load testing and bounce back testing. Thorough inspection means that you can make sure your unit lasts as long as possible. Learn more about testing services.
