About this course
The battery is the part every driver meets, usually at the worst moment. This classroom explains how a lead-acid battery stores and delivers energy, why batteries fail without warning in cold weather, how to test voltage with a multimeter, and how to replace a battery or jump-start a car safely with correct cable order. You will know how to prevent the most common starting failure and what to do when it happens anyway.
