How do you replace the battery in a 1999 Chrysler Concorde?

== == == == The procedure for removal and replacement is basically the same for all autos, not just your Concord, so this procedure is generic in nature. The battery has two TERMINAL POSTS, one of which is electrically positive ["hot"], and is usually identified on the battery top with a "+" symbol, and/or the abbreviaton "POS." The other terminal is electrically negative ["ground"] and is identified on the battery top with a "-" symbol, and/or the abbreviation "NEG." To help prevent placing the wrong cable on the terminal of opposite polarity, the posts, and cable clamps are different sizes [diameters], with the positive terminal being slightly larger than the negative. Usually, but not always, the battery cables are identified by the insulation on the positive cable being RED, and the negative cable insulation being BLACK. If, in placing a clamp to a post, you notice that the clamp either is too small to fit the terminal, or too large and loose to fit, THEN you are trying to put the cable/clamp on the WRONG terminal post! Pay very close attention to prevent a REVERSE polarity connection, as this can DESTROY many EXPENSIVE ELECTRONIC COMPONENTS in your vehicle. Both the negative and positive cables are terminated, on their battery ends, with a "split" clamp which encricles the round terminal posts. The clamps are secured to the terminal with a cross bolt which tightens the clamp to the post. A wrench is needed to tighten or loosen the bolt. FOR SAFETY, anytime you are working on or near electrically energized wires or components, ALWAYS DISCONNECT the negative cable from the negative terminal BEFORE doing anything else. It is IMPORTANT that the NEGATIVE [GROUND] cable is removed FIRST because IF the metal wrench should contact between the negative terminal and a grounded metal body component, NOTHING WILL HAPPEN. On the other hand, IF a metal wrench contacts both the positive terminal and grounded metal, WHILE THE NEGATIVE GROUND cable is still connected, a monsterous SHORT CIRCUIT will result, throwing arc sparks everywhere, possibly causing the wrench to overheat, burning your hand, and in the worst case, COULD cause the battery to EXPLODE, spraying shrapnel and SULPHURIC ACID EVERYWHERE !!!!! ALWAYS COMPLETELY DISCONNECT THE NEGATIVE CABLE FIRST ! Once the negative and positive battery cables have been removed, the battery retaining mechanism [there are several different types] must be removed. Some are a bracket which clamps over the top of the battery, while most newer vehicles have a triangular "bar" which mates with a slot in the bottom edge of the battery case. This secures the battery in the tray, and prevents the battery from "bouncing" out. Once the two cables and the retainer have been removed, the battery can be lifted out of the vehicle. Batteries are very heavy relative to their physical size, so be sure to have good footing, good balance, and use safe lifting procedures to prevent physical injury. Installation of the new/replacement battery is simply a matter of reversing the above procedure. Good luck. j3h
