Victron 12V/220Ah AGM Deep Cycle Battery with M8 threaded insert terminals

Description

Victron 12V/220Ah AGM Deep Cycle Battery with M8 threaded insert terminals

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 use of high purity materials and lead calcium grids ensure that AGM products have particularly low self-discharge so that they will not go flat during long periods without charge. These AGM products 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.

Features

• 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.
• 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. 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.
• Cycle life of Victron batteries: Batteries age due to discharging and recharging. The number of cycles depends on the depth of discharge. 
• Battery charging: longer battery life with Victron 4-step adaptive charging:
• 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.
• 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 selfdischarge (Battery Refresh mode).
• Charge current: The charge current should preferably not exceed 0,2C (20A for a 100Ah battery).The temperature of a battery will increase by more than 10°C if the charge current exceeds 0,2C. Therefore temperature compensation is required if the charge current exceeds 0,2C.
