The XS Power D3100 is a Group 31 deep-cycle AGM battery built for high-current work: 1,376 cold cranking amps, a 5,000-amp max burst and 273 minutes of reserve capacity. It suits trucks, UTVs, RVs and audio or accessory builds that need big cranking power plus steady deep-cycle draw. Its sealed spill-proof case and low internal resistance set it apart from ordinary starting batteries. At 78 lbs it is heavy, and its 4.3-star reception is good but not flawless.
