Our website applies a standard freight charge on most orders of $15.00 AUD including GST per delivery, regardless of quantity ordered. Heavy items such as Sealed Lead Acid (SLA) and large Lithium batteries are an exception to this ....extra freight charges may apply due to weight, transport method and delivery location. We will calculate this and notify you of any extra freight charge after your order is placed. This extra freight charge is at cost- meaning we seek to make no profit on freight. Please feel free to contact us for a quote on freight prior to ordering.

Brand

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

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.

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.

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.

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.

UL94 V-0 RATED FLAME RETARDANT CASING/HOUSING This product's casing/housing is classed UL94 V-0. In simple terms, this means that the casing/housing is considered flame retardant in accordance with the plastics flammability standard.
