Built Dakota tough, this 12 volt lithium battery packs a big punch. Engineered with Lithium Iron Phosphate (LiFePo4) technology this battery has twice the power, half the weight, and lasts 4 times longer than a sealed lead acid battery – providing exceptional lifetime value. 23 Amp hours of capacity provides a full day of power for high amp draw electronics like Garmin fish finders, ice augers, or anything where you need a longer run time. Same performance as our legendary 10 Ah battery, but with 130% more capacity. Replacement for 18Ah & 20Ah SLA batteries including size UB12180, FM12180, 6fm18 and others.
