Calcium Maintenance-Free vs Hybrid vs Low AntimonyTest #2 – Shelf LifeRESERVE CAPACITYChart D compares the percent of reserve capacity retained while in stock, withoutrecharging. Compare the rate of decline of the Hybrid vs. Calcium Maintenance-Freeafter 12 months. While the Calcium Maintenance-Free retains most of its capacity, theHybrid loses more than 65% and the Low Antimony loses 95% of its reserve capacity.In fact, after 12 months withoutcharging, Low Antimony and manyHybrid batteries will not hold acharge, while CalciumMaintenance-Free batteriesrecharge easily, with no capacityloss.SPECIFIC GRAVITYWhen comparing specificgravity and open circuit voltageloss per day, the Hybrid selfdischarges one-and-a-half times asfast, and the Low Antimony selfdischarges three times as fast asthe Calcium Maintenance-Free. Thishelps explain the previous charts.Lower stand loss means morepowerful batteries for your customers.Using the J240b life cycle test,CARQUEST’s CalciumMaintenance-Free shows anotherdramatic difference in performance.It delivers over 40% more life cycles than the Hybrid and 140% more than theLow Antimony. This is especially important when considering warranty expenses,consumer satisfaction and repeat business.J240b Life Testing onGroup 26 BatteriesVOLTS @ 30 SECONDS9.29.08.88.68.48.28.07.87.67.47.2CHART GLow SbCalciumHybrid0 1000 2000 3000 4000 5000 6000 7000CYCLESJ240b Life Testingon Group 26 Batteries @ 175°FVOLTS @ 30 SECONDS8.808.40Calcium8.007.60Hybrid7.20400 600 800 1000 1200 1400 1600 1800CYCLESCHART H250
