* Where allowed by applicable law and regulations, batteries must be shipped via Ground shipments only.The question, “How long will a deep cycle battery last?” depends on many factors including the usage and maintenance of deep cycle batteries. Product Name: Victron 12V/60Ah Gel Deep Cycle Battery, 2 Year Warranty Therefore temperature compensation is required if the charge current exceeds 0,2C. 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☌ if the charge current exceeds 0,2C. The centre point for temperature compensation is 25☌ / 70☏. The recommended temperature compensation for Victron VRLA batteries is -4 mV / Cell (-24 mV /☌ for a 12V battery). Temperature compensation is required when the temperature of the battery is expected to be less than 10☌ / 50☏ or more than 30☌ / 85☏ during long periods of time. The charge voltage should be reduced with increased temperature. Effect of temperature on charging voltage: The recommended charge voltage settings for a 12V battery.ġ4. Optimum charge voltage of Victron VRLA batteries: This charge method is used for starter batteries in vehicles and in uninterruptible power supplies (UPS).ġ3. Once a pre-set voltage has been reached the battery is kept at that voltage (the float phase). Battery charging in case of standby use: constant voltage float charging:ĭuring the first phase the battery is charged with a limited current (the bulk phase). Once every week the charge voltage is increased to the absorption level for a short period to compensate for self discharge (Battery Refresh mode).ġ2. 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. Research has shown that this will reduce internal gassing to a safe level. The Battery Safe Mode will limit the rate of voltage increase once the gassing voltage has been reached. In order to prevent excessive gassing, Victron has invented the ‘Battery Safe Mode’. The Victron four-step adaptive charge curve solves the 3 main problems of the 3-step curve: The 4-step adaptive chare curve is the result of years of research and testing. Victron developed the adaptive charge curve. Battery charging: longer battery life with Victron 4-step adaptive charging: due to accelerated corrosion of the positive plates).ġ1.

The third and last phase is the float phase: the voltage is lowered to standby level, sufficient to compensate for self-discharge.ĭisadvantages of the traditional 3-step charge curve:Ī full absorption period after a shallow discharge will overcharge the battery, again reducing service life (a.o. Battery charging in case of cycle use: the 3-step charge curve:ĭuring the absorption phase the charge voltage is kept at a relatively high level in order to fully recharge the battery within reasonable time. The number of cycles depends on the depth of discharge.ġ0. High temperature has a very negative effect on service life.Ĭapacity reduces sharply at low temperatures.īatteries age due to discharging and recharging. On the other hand, Gel batteries have a longer service life, both under float and cycling conditions.ħ. Repeatedly deep and prolonged discharge has a very negative effect on the service life of all lead acid batteries, Victron batteries are no exception.ĭue to their construction, Gel batteries have a lower effective capacity at high discharge currents. Victron VRLA batteries can therefore be stored for up to a year without recharging, if kept under cool conditions. The self-discharge doubles for every increase in temperature by 10☌. Gel batteries in general have a longer service life and better cycle capacity than AGM batteries. Here the electrolyte is immobilized as gel. In these batteries the electrolyte is absorbed into a glass-fibre mat between the plates by capillary action.

VRLA batteries are maintenance free for life.ĪGM stands for Absorbent Glass Mat. Gas will escape through the safety valves only in case of overcharging or cell failure. VRLA stands for Valve Regulated Lead Acid, which means that the batteries are sealed.
