Absorbent Glass Mat Battery - Description

DESCRIPTION

WARNING: The Absorbent Glass Mat (AGM) starter battery should only be charged and tested with the OTC One Step Battery Analyzer and Charger or equivalent. Never test the AGM battery with a Midtronics Micro 420 battery tester.

The starter battery (also referred to as the main vehicle battery) is located in a floor well forward of the driver seat. A metal cover retained by four screws protects the top of the battery. To access the battery and battery cover the left floor covering must be removed. A breather line runs from the battery through the bottom of the recess well to the outside of the vehicle.

The battery negative cable is routed out of the well to a isolating connector on the left side of the instrument panel center stack, above the accelerator pedal. When vehicle service requires disconnecting the battery this connector provides a convenient method of isolation.

A 300 amp melting fuse is incorporated into the battery positive cable. If the fuse melts, the battery positive cable must be replaced. The main reason this fuse would melt is from reversing polarity while jump starting the vehicle.

NOTE: Removing this isolating connector only disconnects power to the starter battery. If the vehicle is equipped with an auxiliary battery, that must be also be disconnected to prior to vehicle service.

When optional equipment is installed, the standard 12-volt 100Amp battery may be replaced with a 12-volt 95Amp Absorbent Glass Mat (AGM) battery. Electrolyte levels for AGM batteries should be checked every 25,000 miles or every two years.
