  • Absorbed Glass Mat (AGM) Battery
  • Valve Regulated Lead Acid (VRLA) Technology
  • 165 Amp Hours
  • 12 Volts
  • Deep Discharge Recovery

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

More Product Features:

VLRA 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. 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 the 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 for 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.

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 effective capacity decreases with increasing discharge current. Please note that the capacity reduction will be even faster in case of a constant power load, such as an inverter. Victron's AGM deep cycle batteries have excellent high-current performance and are therefore recommended for high-current applications such as engine starting. Due to their construction, Gel batteries have a lower effective capacity at high discharge currents. On the other hand, Gel batteries have a longer service life, both under float and cycling conditions.

Battery Charging: Longer Battery Life with Victron 4-Step Adaptive Charging:

Victron developed the adaptive charge curve. The 4-step adaptive charge curve is the result of years of research and testing.

The Victron four-step adaptive charge curve solves the 3 main problems of the 3-step curve:

  • Battery Safe Mode: In order to prevent excessive gassing, Victron has invented the ‘Battery Safe Mode’. The Battery Safe Mode will limit the rate of voltage increase once the gassing voltage has been reached. Research has shown that this will reduce internal gassing to a safe level.
  • Variable Absorption Time: Based on the duration of the bulk stage, the charger calculates how long the absorption time should be in order to fully charge the battery. If the bulk time is short, this means the battery was already charged and the resulting absorption time will also be short, whereas a longer bulk time will also result in a longer absorption time.
  • Storage Mode: After completion of the absorption period the battery should be fully charged, and the voltage is lowered to the float or standby level. If no discharge occurs during the next 24 hours, the voltage is reduced even further and the battery goes into storage mode. The lower storage voltage reduces corrosion of the positive plates. Once every week the charge voltage is increased to the absorption level for a short period to compensate for self-discharge (Battery Refresh mode).

*Please Note: This battery is a special order and requires 4-5 business days before shipping.
