Xtreme Charge is well suited to both AGM and other Maintenance free batteries. The Combination of Patented Pulse technology and the patented charging algorithm will typically allow it to more completely charge all regular and high performance batteries, while also maintaining an excellent charge profile suitable for other types of Flooded or standard batteries. Pulse Tech"s unique technology will increase the duty and life cycle of all sizes or types of 12 volt lead acid batteries by minimizing the size and amount of sulphation on the lead plates, therefore allowing the battery to accept as much charge as possible. The XC 100-P patented pulse will help new batteries stay in as new condition, as well as improve older batteries" charge capacity back up to as new standards. You can expect duty cycles to be extended 3-5 times over similar batteries charged on a standard charger. This charger is suitable for all flooded, Gel, AGM and other maintenance free batteries.
