Buick Regal: Battery - North America
The original equipment battery is maintenance free. Do not remove the cap and do not add fluid.
If equipped with a V6 engine, the battery is under the trim panel on the left side of the rear cargo area.
If equipped with an L4 engine, the battery is under the hood. See Engine Compartment Overview. Refer to the replacement number on the original battery label when a new battery is needed.
The battery is an Absorbed Glass Mat (AGM) 12-volt battery.
Installation of a standard 12-volt battery will result in reduced 12-volt battery life.
When using a 12-volt battery charger on the 12-volt AGM battery, some chargers have an AGM battery setting on the charger.
If available, use the AGM setting on the charger, to limit charge voltage to 14.8 volts.
