The Duralast Platinum H6-AGM is a group-size H6 absorbent glass mat battery built for cars that came with AGM from the factory or run heavy electrical loads. It is spill-proof and can be mounted in more positions than a flooded battery, and it is rated for repeated discharge and recovery. It carries a 4-year free-replacement warranty. Owners report strong cold-weather cranking and a direct fit in the original battery tray. The main complaints are that it costs more than flooded alternatives and that a few units failed early.
