AGM Deep Cycle Battery, 12V, 8 Ah

The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches.

A truly innovative 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. 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. 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 lighter - an additional advantage of the new chemistry is a slightly smaller size and less weight compared to our standard deep cycle AGM batteries.

VRLA technology - VRLA stands for Valve Regulated Lead Acid, which means that the batteries are sealed. Gas will escape through the safety valves only in case of overcharging or cell failure. VRLA batteries are maintenance free for life.

Low Self-Discharge - Because of the use of lead calcium grids and high purity materials, Victron VRLA batteries can be stored during long periods of time without recharge. The rate of self-discharge is less than 2% per month at 20°C. The self-discharge doubles for every increase in temperature by 10°C. Victron VRLA batteries can therefore be stored for up to a year without recharging, if kept under cool conditions.

Are Victron AGM batteries good?

Victron recommends their AGM deep cycle batteries for high-current applications like engine starting due to their excellent high-current performance.

What is the life expectancy of a AGM deep cycle battery?

AGM batteries are recognized for their operation without the need for maintenance and have a lifespan of 7 to 10 years. Typically, they provide approximately 600 to 1,000 cycles, which is based on the discharge level and the quality of management.
