Maybe you don’t drive your vehicle daily, or you have a car, motorcycle or boat that you only occasionally take out from time to time. Is your vehicle in storage for seasons during the year? When you bring it out of storage you might have a dead battery. How do you revive that dead battery?
There is nothing worse than the idea of a loved one on the side of the road with a dead battery, or a family member stuck in a parking lot unable to start their car due to a dead battery. In the past, you were stranded until you or your loved one could get help. How could you help them? With a regular battery charger you would need to be near a power outlet to safely charge or maintain your battery. Not any more.
Wherever you are, whatever the situation, the CS FREE® will be within reach. Bring your battery back to life using our unique Adaptive Boost technology. It is safe for your vehicle, the battery, and anyone using it. It will have you back on the road within 15 minutes.
