How does a battery work?

Your battery does what it does best when it’s sitting idly under your hood. It stores chemical energy when it has nothing else to do, and waits to release it as electricity when you need it. When you put your key into the ignition and turn it to the “ON” position, your battery receives a signal to go into action. It releases that stored chemical energy as electricity. This is what allows the engine to crank.

One of the reasons is a weak or dead battery. If you have a battery tester that can measure cranking amps, use it to see if the battery is weak. If you can’t test the battery, try jump-starting . If the car starts right away, your problem is most likely a dead battery.  Charge the battery and clean the terminals and cable connectors to ensure good contact. If your car does not start by jump-starting, you may have a problem with your starter, alternator or another component of the electrical system. Be sure to read and follow all safety and handlinginstructions on the battery and this website.

To charge an automotive battery, refer to your owner's manual and your battery charger manual for instructions. Read and follow all safety and handling instructions that came with your charger and battery. Battery chargers will charge a battery based on its condition and at a rate appropriate for its state of charge. Charging voltages run from 13.8 volts to a maximum of 15.5 volts for most applications. Finally, remember that batteries contain sulfuric acid that can cause severe burns, and hydrogen-oxygen gases that can be explosive. Charge in a well-ventilated area. Be sure to follow all safety and handling.

How do I jump-start my vehicle?

See the step-by-step instructions on our Jump-starting page. You'll need a set of jumper cables and another vehicle with a charged battery. You can find cables at gas stations, auto parts stores or just about anywhere you buy car parts. Be sure to read and follow the safety and handling information on the battery, this website, and on the jumper cables.

We recommend fully charging your battery at the first opportunity after its being jump-started.

A 12-volt battery is considered fully charged at 12.6 volts.

Idling or frequently making short stop-and-go trips will not recharge the battery effectively.

Charging should never occur without vent caps. In general, vent caps should always remain tightly in place and in a level position.
