A truly innovative battery. Victron 12 Volt 230 AH Deepcycle Battery:

• The 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 case of repeated 100% discharge of the battery, and new
  additives to the electrolyte reduce sulfation in case of deep discharge.
• Exceptional 100% depth of discharge (DoD) performance – Tests 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 = 0,2C₂₀, followed by approximately two hours rest in discharged condition,
  and then a recharge with I = 0,2C₂₀.
• The two hours rest period in discharged condition will damage most batteries within 100 cycles, but not the Super Cycle battery.
• We recommend the Super Cycle battery for applications where an occasional discharge to 100% DoD, or frequent discharge to 60-
  80% DoD is expected.
• Smaller and lighter – An additional advantage of the new chemistry is a slightly smaller size and less weight compared to our standard deep cycle AGM batteries.
• Low internal resistance -The internal resistance is also slightly lower compared to our standard deep cycle AGM batteries.
