AGM Super Cycle Battery 12V 15Ah A truly innovative battery AGM Super Cycle batteries are the result of the latest developments in the field of battery electrochemistry. The paste on the positive plates does not soften quickly, even if the battery is discharged to 100% several times. In addition, the new additives in the electrolyte reduce sulphation in the event of a deep discharge. Exceptional performance despite repeated deep discharge Tests have shown that the Super Cycle battery continues to perform even after at least three hundred 100% deep discharges. During the test, the batteries were discharged daily to 10.8 V with I = 0.2 C20. They were then left in the discharged state for two hours and then recharged with I = 0.2 C20. Most batteries will be damaged if left in a discharged state for two hours 100 times, but not the Super Cycle battery. Smaller and lighter Another advantage of the new chemical composition is that the batteries are smaller and weigh less compared to our previous deep cycle AGM batteries. Lower internal resistance The internal resistance is also slightly lower than our usual deep cycle AGM batteries.
