I replaced the factory battery with an Odyssey Battery the first week I had the jeep back in 2008 when it was new. I put the factory jeep battery into my wife's car and it lasted until we sold it. Depending on what you have done to the jeep, a factory battery may not be enough. Do you have a winch, extra lights, air compressor, upgraded stereo system or anything else that may put extra draw on the electrical system? It takes about 150 amps for a few seconds to crank a normal engine over, but a winch under full load can draw 450 amps and for a much longer time.
