THE BATTERY ON MY 2002
Do you drive it every day? The clock can kill a battery in 2 days if it is not run. How did you check the battery>? Volts, amps?,Electrolytes? The battery must maintain minimum 13.5 volts at all times. The electrolyte fluid can tell you a lot about the condition of a battery, One dead or weak cell, you might as well trash it. Just because it is a newer battery doesn't mean it is good, I've taken them off the shelf, dead. If you have an amp meter on the dash, it should always show charging, or 13+ volts, a light will only show when it is not charging or a very low battery is being charged, depends on the car. Get one of those floaty ball things at the auto store and check the water in the battery, and make sure it is up on water, bottled water works good, distilled type, no minerals. Hope this helps.
