Victron Deep Cycle Batteries
BATTERY KING STOCKIST OF VICTRON DEEP CYCLE BATTERIES
1. Gel and AGM batteries
VRLA AGM: design life 7-10 years
VRLA GEL: design life 12 years
VRLA GEL 2 Volt cells: design life 20 years
The AGM range has very low internal resistance making them particularly suitable for high current discharge applications such as for inverters, thrusters and winches.
The GEL model range offers best deep cycle durability and overall longer life. The use of high purity materials and lead calcium grids ensure that for both AGM and GEL products have particularly low self-discharge so that they will not go flat during long periods without charge. Both ranges are supplied with M8 drilled, flat copper terminals ensuring best possible connection contact and eliminating the need for battery terminals.
The batteries are compliant with both CE and UL specifications in ABS fireproof containers and come with Victron’s 2 year world-wide warranty.

2. Super Cycle batteries
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 An additional advantage of the new chemistry is a slightly smaller size and less weight compared to our standard deep cycle AGM batteries. The 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 = 0,2C20, followed by approximately two hours rest in discharged condition, and then a recharge with I = 0,2C20)
≥ 700 cycles @ 60% DoD (discharge during three hours with I = 0,2C20, immediately followed by recharge at I = 0,2C20)
≥ 1000 cycles @ 40% DoD (discharge during two hours with I =0,2C20, immediately followed by recharge at I = 0,2C20)
3. VRLA TECHNOLOGY
1. 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.
2. Sealed (VRLA) AGM Batteries
AGM stands for Absorbent Glass Mat. In these batteries the electrolyte is absorbed into a glass-fibre mat between the plates by
capillary action. As explained in our book ‘Energy Unlimited’, AGM batteries are more suitable for short-time delivery of high currents than gel batteries.
3. Sealed (VRLA) Gel Batteries
Here the electrolyte is immobilized as gel. Gel batteries in general have a longer service life and better cycle capacity than AGM batteries.
4. 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.
5. Exceptional Deep Discharge Recovery
Victron VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge. Nevertheless repeatedly deep and prolonged discharge has a very negative effect on the service life of all lead acid batteries, Victron batteries are no exception.
6. Battery Discharging Characteristics
The rated capacity of Victron AGM and Gel Deep Cycle batteries refers to 20 hour discharge, in other words: a discharge current of 0,05 C.
The rated capacity of Victron Tubular Plate Long Life batteries refers to 10 hours discharge. The effective capacity decreases with increasing discharge current (see table 1). Please note that the capacity reduction will be even faster in case of a constant power load, such as an inverter.
