The following schematic diagram shows Jeep Grand Cherokee Battery Cable Harness. The Grand Cherokee Battery battery is made up of six individual cells that are connected in series. Each cell contains positively charged plate groups made of lead oxide, and negatively charged plate groups made of sponge lead.
A normal vehicle electrical system will draw from 5 to 25 milliamperes (0.005 – 0.025 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper working order. The 25 milliamperes are needed to supply Powertrain Control Module (PCM) memory, digital clock memory, and electronically tuned radio memory.
