Describe the new page here. A car battery is a chemical energy storage device capable of releasing this energy in the form of direct current. All car batteries( contain a positive and negative electrode immersed in an electrolyte, with all the contents stored in a plastic container.

All Electra batteries are lead-acid, which means that they have positive and negative electrodes made of lead compounds immersed in a dilute sulfuric acid electrolyte. Lead-acid batteries are secondary batteries, which means they can be recharged after they have been exhausted. Primary batteries can only be discharged once and then disposed of; examples are some types of batteries used in flashlights and radios.
