FAQs

It applies a controlled load to the battery and shows whether it can deliver adequate current under starting conditions.

Connect positive clamps first, then negative, start the donor vehicle, wait a few minutes, then attempt to start the disabled car.

Most batteries last three to five years. Replace sooner if you notice slow cranking, dim lights, or frequent jump starts.

Smart chargers adjust voltage automatically and work with most modern cars, but always check the manual for manufacturer recommendations.

Disconnect cables, apply a baking soda and water solution, scrub with a wire brush, rinse, and dry before reconnecting.
