The AGM range has very low internal resistance, making them particularly suitable for high current discharge applications such as for inverters, thrusters, and winches.VRLA AGM: design life 7-10 yearsA truly innovative batteryThe AGM Super Cycle batteries are the result of recent battery electrochemistry developments. The paste of the positive plates is less sensitive to softening, even in the case of repeated 100% discharge of the battery, and new additives to the electrolyte reduce sulfation in the case of deep discharge.What is the difference between Super Cycle and Deep CycleSuper Cycle batteries are a type of deep cycle battery, specifically designed for applications requiring frequent or deep discharges, and can withstand more cycles at a higher depth of discharge than standard deep cycle batteries.They are often built with enhanced chemistries to improve their performance and lifespanExceptional 100% depth of discharge (DoD) performanceTests have shown that the Super Cycle battery does withstand at least three hundred 100% DoD cycles. The tests consist of a daily discharge to 10,8V with I = 0,2C, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0,2C. The two-hour rest period in discharged condition will damage most batteries within 100 cycles, but not the Super Cycle battery.Victron recommends the Super Cycle battery for applications where an occasional discharge to 100% DoD, or frequent discharge to 60-80% DoD is expected.Smaller and lighterAn additional advantage of the new chemistry is a slightly smaller size and less weight compared to our standard deep-cycle AGM batteries.Low internal resistanceThe internal resistance is also slightly lower compared to our standard deep-cycle AGM batteries.Cycle life 300 cycles @ 100% DoD (discharge to 10,8V with I = 0,2C, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0,2C) 700 cycles @ 60% DoD (discharge during three hours with I = 0,2C, immediately followed by recharge at I = 0,2C) 1000 cycles @ 40% DoD (discharge during two hours with I = 0,2C, immediately followed by recharge at I = 0,2C)Effect of temperature on charging voltageThe charge voltage should be reduced with increased temperature. Temperature compensation is required when the temperature of the battery is expected to be less than 10C / 50F or more than 30C / 85F during long periods of time. The recommended temperature compensation for Victron VRLA batteries is -4 mV / Cell (-24 mV /C for a 12V battery). The centre point for temperature compensation is 25C / 70F.SizingDownloadVictron Energy AGM Super Cycle Battery Datasheet .input-wrapper a { text-decoration: none; / Removes underline / background-color: transparent; / Ensures no background color / } .input-wrapper a:hover { text-decoration: underline; / Adds underline on hover / background-color: transparent !important; / Removes grey highlight / }
