The DL+12V 280Ah just got bigger! Welcome the all new DL+ 12V 315Ah!When you go off the grid during a Dakota winter you need to be prepared for all that mother nature can throw at you. With the new DL+ 12V 315 Ah battery, we built our most compact and powerful battery yet — ready for long expeditions in your RV, extended ocean voyages in your boat, or plenty of power for your off-grid system. Engineered for maximum energy density, this battery has 315 Amp Hours of capacity in a waterproof battery case the size of a single 100 Amp Hour battery. That’s 6X the amount of usable power of a single group 31 AGM battery. Plus, up to 1,000 cold cranking amps of engine starting power, making this battery the ultimate single battery solution for boats, RVs, or any vehicle where you need a house battery that can jump-start your engine. Built out of Lithium Iron Phosphate (LiFePO4) technology and reinforced with a ruggedized marine spec plastic case, this is a battery built to last. With a lifespan of 5,000 charge cycles this battery will last up to 6 times longer than your typical AGM battery – providing exceptional value over time. Optimized for marine/boating, solar energy, RVs & electric vehicles. LiFePO4 optimized charger included. 11-year warranty. This is our original 100Ah battery, re-engineered with 180% more capacity in a similar-sized case.**The DL+ 12v 315Ah battery is a Group 31-sized battery. The bottom footprint dimensions are 13.31″L x 7.24″W x 10″H (338mm × 202mm × 252mm) and will fit in most Group 31-sized battery trays. The top of the DL+ 12v 315Ah is a little wider, incorporating handles, the dimensions at the top are 15.06″L x 7.24″W x 10″H (383mm x 184mm x 254mm) which means, some Group 31 size battery boxes may not be compatible.**
