Hummer H3 Batteries Available Here. Batteries are the unsung heroes of the automotive age. They are the small boxes sitting in our vehicles’ engine compartments, and they hold the ability to start our day off right or ruin it completely. The battery’s primary function is to provide the electrical power needed to start your car’s engine. Once that task is completed, the battery relaxes, but its work is not done. While the vehicle is running, batteries act as an electrical stabilizer that provides an added boost when the car’s electrical needs exceed the charging systems capabilities. In our inventory of batteries, we have the right one for you.
