What actually happens during a short circuit?

A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low-resistance conductor, like a wire. With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.

How do I know if my battery is shorted?

Charge the battery fully, and check it with a volt meter. You must get a reading of 12 volts or more for a good battery. A reading of 10.5 volts or less indicates that one or more of the cells have shorted out. The shorted cell is preventing the battery from holding a full charge.

How do you protect a battery from a short circuit?
