POWR-Plus batteries are designed to give more energy and maximum battery life. All batteries are custom built when an order is received. All batteries have high capacity industrial type deep cycle cells with flag type terminals on the positive and negative posts. Heat-sealed cell covers eliminate the major source of electrolyte leakage, reducing corrosion build-up. Tough steel cases are powder coated for acid resistance and have lifting handles. Cycle life of these batteries is 5,000 cycles at 20% depth of discharge or 1500 cycles at 80% depth of discharge. IBE batteries have an 8-year warranty. The first 5 years are full replacement. The last 3 years are prorated. Capacity @ 20-hr rate 418 A-h Capacity @ 100-hr rate 510 A-h Weight lbs 490 Dimensions L" x W" x 24" H 21.5 X 6.62
