Deep Cycle Gel Battery 12V 110Ah - VICTRON

Deep Cycle Gel Battery 12V 110Ah - VICTRON

The gel batteries have a cycling capacity and a life longer than the AGM batteries and do not require maintenance unlike the open lead batteries. These are the most suitable solar batteries for slow discharges. Their lifetime and cycling performance is 10 to 20% higher than those of AGM batteries.

Battery intended for energy storage in autonomous site : house, motorhome, boat

This battery has a large storage capacity, it is designed to store solar or wind energy and return it to 12V or 220V via an inverter.

As with any "slow discharge" battery, we presume the use of a charge controller to not overload it or, on the contrary, not to descend below 50% of the discharge, which would reduce the battery life in both cases.

VICTRON GEL batteries do not require maintenance throughout their lifetime.

VICTRON solar batteries offer the guarantee of an irreproachable manufacturing quality and excellent durability

VRLA technology for GEL and AGM solar batteries

VRLA is the abbreviation of Valve Regulated Lead Acid, which means the battery is waterproof. Gas will escape by

safety valves only in case of overload or failure of elements. VRLA batteries have exceptional leak resistance and can be used in all positions.

GEL and AGM batteries are maintenance-free.

Waterproof GEL batteries (VRLA)

In this type of battery, the electrolyte is immobilized as a gel. The GEL batteries generally have a longer life and a better cycling capacity than the AGM batteries.

Low self-discharge

Thanks to the use of lead-calcium grids and high purity materials, VRLA Victron batteries can be stored for a long time without charging. The self-discharge rate is less than 2% per month at 20oC. The double self-load for each 10oC of temperature increase. In cool environment, Victron's VRLA batteries can be stored up to one year without charging.

Extraordinary deep discharge recovery

Victron VRLA batteries have an exceptional recovery capacity even after a deep or prolonged discharge. It should be noted, however, that the frequent deep or prolonged discharges have a negative impact on the life of any lead/acid battery, and that the Victron batteries are no exception.

Battery discharge characteristics

The nominal capacities of the Victron batteries are given for a discharge in 10 hours, or for a discharge current of 0.1C. The effective capacity for faster discharges with high intensities (see table 1). Capacity reduction will be even faster with constant power consumers such as converters.

Because of their design, Gel batteries have a lower effective capacity at high intensity. On the other hand, Gel batteries have a better life in floating and cycling use.

High temperatures have a very negative impact on life. The foreseeable life of the GEL batteries may vary by 30% depending on the average temperature level of the environment is 20° or 30°.

Batteries age due to discharges and recharges. The number of cycles depends on the discharge depth as shown in Figure 2.

A better lifespan thanks to Victron's 4-step adaptive charge

Victron Energy has developed the 4-step adaptive charge. This innovative technology is the result of several years

research and testing. Victron's adaptive charging method eliminates the 3 major drawbacks of the traditional charge in 3 steps:

BatterySafe function:

To avoid excessive gas, Victron invented the BatterySafe function. The BatterySafe function slows the rise of the load voltage when the gas voltage is reached. Studies show that this process brings internal gas to a safe level.

Variable absorption time:

The Victron charger calculates the optimal duration of the absorption phase according to the duration of the initial load phase (Bulk). If the Bulk phase was short, the battery was unloaded and the absorption time will be automatically shortened. A longer initial load phase will give a longer absorption time.

Standby:

Once the absorption phase is complete, the battery is in principle fully charged and the voltage is reduced to the maintenance level (Float). Then and if the battery is not requested for 24 hours, the voltage is still reduced and the battery charger switches to "best" mode. This "veille" tension minimizes corrosion of positive plates. The voltage will then be increased to the absorption level once a week over a short period to compensate for the self-discharge ( Battery Refresh function).

Effects of temperature on charge voltage and optimal charge current

The load voltage shall be reduced as the temperature increases. The temperature compensation is necessary when the battery temperature can descend below 10°C / 50°F or exceed 30°C / 85°F over a prolonged period. The recommended temperature compensation for Victron VRLA batteries is -4 mV/element (-24 mV/°C for a 12V battery). The median temperature compensation point is 20°C / 70°F.

The charging current should preferably not exceed 0.2 C (20 A for a 100 Ah battery). The battery temperature will increase by more than 10°C if the charge current is greater than 0.2 C. Temperature compensation is therefore essential for load currents greater than 0.2 C.
