Cycle life of Victron batteries: Batteries age due to discharging and recharging. Effect of temperature on capacity: As is shown by the graph below, capacity reduces sharply at low temperatures.įig. Table 2: Design service life of Victron batteries under float serviceĨ. The service life of Victron batteries as a function of temperature is shown in table 2. Effect of temperature on service life: High temperature has a very negative effect on service life. On the other hand, Gel batteries have a longer service life, both under float and cycling conditions.ħ. Due to their construction, Gel batteries have a lower effective capacity at high discharge currents. Our AGM deep cycle batteries have excellent high current performance and are therefore recommended for high current applications such as engine starting. Table 1: Effective capacity as a function of discharge time (the lowest row gives the maximum allowable 5 seconds discharge current) Please note that the capacity reduction will be even faster in case of a constant power load, such as an inverter.
The effective capacity decreases with increasing discharge current (see table 1). The rated capacity of Victron Tubular Plate Long Life batteries refers to 10 hours discharge. 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. 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.Ħ. Exceptional Deep Discharge Recovery: Victron VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge. Victron VRLA batteries can therefore be stored for up to a year without recharging, if kept under cool conditions.ĥ. The self-discharge doubles for every increase in temperature by 10☌. The rate of self-discharge is less than 2% per month at 20☌. 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. Gel batteries in general have a longer service life and better cycle capacity than AGM batteries.Ĥ. Sealed (VRLA) Gel Batteries: Here the electrolyte is immobilized as gel.
As explained in our book ‘Energy Unlimited’, AGM batteries are more suitable for short-time delivery of high currents than gel batteries.ģ. In these batteries the electrolyte is absorbed into a glass-fibre mat between the plates by capillary action. Sealed (VRLA) AGM Batteries: AGM stands for Absorbent Glass Mat.

VRLA batteries are maintenance free for life.Ģ. Gas will escape through the safety valves only in case of overcharging or cell failure. VRLA technology: VRLA stands for Valve Regulated Lead Acid, which means that the batteries are sealed. VRLA GEL 2 Volt cells: design life 20 yearsġ.
The batteries are compliant with both CE and UL specifications in ABS fireproof containers and come with Victron's 2 year world-wide warranty. Both ranges are supplied with M8 drilled, flat copper terminals ensuring best possible connection contact and eliminating the need for battery terminals. The use of high purity materials and lead calcium grids ensure that for AGM products have particularly low self-discharge so that they will not go flat during long periods without charge.
