Product Description

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) Gel Batteries:

Here the electrolyte is immobilized as the gel. Gel batteries, in general, have a longer service life and better cycle capacity than AGM 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.

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.

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.

Effect of temperature on service life:

High temperature has a very negative effect on service life.

Cycle life of Victron batteries:

Batteries age due to discharging and recharging. The number of cycles depends on the depth of discharge.

Battery charging in case of cycle use: the 3-step charge curve:

The most common charge curve used to charge VRLA batteries in case of cyclic use is the 3-step charge curve, whereby a constant current phase (the bulk phase) is followed by two constant voltage phases (absorption and float).

During the absorption phase the charge voltage is kept at a relatively high level in order to fully recharge the battery within reasonable time. The third and last phase is the float phase: the voltage is lowered to standby level, sufficient to compensate for self-discharge. 

  • Disadvantages of the traditional 3-step charge curve:
    • During the bulk phase the current is kept at a constant and often high level, even after the gassing voltage (14,34V for a 12V battery) has been exceeded. This can lead to excessive gas pressure in the battery. Some gas will escape through the safety valves, reducing service life.
    • Thereafter the absorption voltage is applied during a fixed period of time, irrespective of how deep the battery has been discharged previously. A full absorption period after a shallow discharge will overcharge the battery, again reducing service life (a.o. due to accelerated corrosion of the positive plates).
    • Research has shown that battery life can be increased by decreasing float voltage to an even lower level when the battery is not in use.

Battery charging: longer battery life with Victron 4-step adaptive charging

Victron developed the adaptive charge curve. The 4-step adaptive chare 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 selfdischarge (Battery Refresh mode).

Battery charging in case of standby use: constant voltage float charging:

When a battery is not frequently deeply discharged, a 2-step charge curve can be used. During the first phase the battery is charged with a limited current (the bulk phase). Once a pre-set voltage has been reached the battery is kept at that voltage (the float phase).

This charge method is used for starter batteries in vehicles and in uninterruptible power supplies (UPS).

Optimum charge voltage of Victron VRLA batteries:

Please see product card.

Effect of temperature on charging voltage:

The charge voltage should be reduced with increased temperature. Temperature compensation is required when the temperature of the battery is expected to be less than 10°C / 50°F or more than 30°C / 85°F during long periods of time.

The recommended temperature compensation for Victron VRLA batteries is -4 mV / Cell (-24 mV /°C for a 12V battery).

The centre point for temperature compensation is 25°C / 70°F.

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.

Product Q&A

Ask Us a Question
  • What size battery charger do I need for my lead acid battery I have in my camper?

    A good battery charger rule of thumb for charging a lead acid battery, is using a charger with output current (amps) of 10-20% of the battery total stored capacity (Ah).

    So, for example if the battery is 12V 100Ah, the charger need to be minimum of 10A and maximum of 20A.  Often splitting the difference at 15% (so a 12V ~15A charger) is a good option. Happy charging!
