   The main battery is either absorbent glass mat (AGM) or enhanced flooded battery (EFB) technology, [11] both supporting an increased number of charging cycles and increased load. This is important because all the car's electrical system must be maintained by the battery after the alternator stops generating current. Often the battery will be ...

   Boosting a dead battery through a battery charger can take anywhere from five to twenty minutes depending on the depth-of-discharge (DOD), health of the vehicle battery, and type of engine (engine displacement). AC power is not usually available for a roadside boost. Jump starters are portable battery devices that allow for jump starting of ...
