Description
Victron 12V/90Ah AGM Deep Cycle Battery with M6 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.

Q & A
-
What size battery do I need for my caravan?
Great question! Your deep cycle battery for your caravan will be a minimum of 100 Amp Hours (Ah).
The average size for a Caravan is 200Ah. Usually, 2 x 100Ah connected in Parallel. However, if your budget allows to upgrade to a Lithium battery you can get a lot more power for the size of the battery. For example, a 200Ah lithium battery can be equivalent to up to 360 Ah of an AGM battery.
To work out exactly what size you require you need to first look at the load you are planning on drawing. The load should be calculated in Amps per hour, or Amp Hours (Ah). Batteries are rated in Amp Hours (Ah) as well.
So, if you are drawing a 50Ah per day, a 100Ah AGM battery can provide power for about 1 day as you do not want to draw more than 50% from your battery. However, it is not always easy to find what each appliance draws. Some popular examples are following:
- 150L 12V Fridge = 2.5 Amps per hour (2.5Ah) - runs for 24 hours a day
- 12V Water Pump = 3.5 Amps per hour (3.5Ah) - only runs for 1 hour a day
- Phone Charger = 0.5 Amps per hour (0.5Ah) - Maybe 4 hours per day
- 12V Fan = 4 Amps per hour (4Ah) - Maybe 4 hours per day
Then you will need to factor in how much charge you are putting in Daily. The charge comes in the way of Solar and in car charging via a DC to DC charger.
Ideally you want enough charge input per day to cover the load drawn, then enough battery storage to last 2 - 3 days without charge.
-
What is best - AGM or lithium battery?
The answer is simple. Lithium is a better product than AGM.
Lithium is lighter, more compact, and powerful, it will also last longer.
However, a lithium battery will cost more, because it is a highly sort after product. Almost everything that has a battery nowadays will have a lithium battery. Mobile phone, Electric Car, Electric Bike and Skateboard just to name a few.
There are situations where you can get away with an AGM battery. If you only need about 100ah (most 4 x 4 set ups), you can purchase 1 x 100ah battery and a battery box and away you go.
However, once you start getting into the larger amperages (200+) it really makes more sense to turn to lithium.
-
How do I charge my caravan battery?
There are three ways to charge your caravan Battery. Either:
- AC to DC - This is using a traditional battery charger that plugs into mains power.
- DC to DC - This is a battery charger connected between the start battery of your tow vehicle and the Caravan Battery. This will charge the battery whilst driving.
- Solar - Solar panels on your roof can be connected to a solar charge controller then to your Caravan Battery.
-
How much solar do I need to keep my caravan battery charged?
Ideally, you want use as much solar as you can fit on the roof. Extra portable solar panels are also good idea if you want to park your van in the shade and run a portable panel from a lead in the sun - please see our solar range here.
Solar is cheap relative to the rest of your system, and it provides so much of your power when you are camping off grid.
However, the solar required depends on the load. Please feel free to contact our team for any specific questions on your battery - 1800 787 278!
