12volt 110 amp AGM Deep Cycle Battery for Caravan Solar Motorhome Off Grid

110Ah Deep Cycle AGM maintenance free

12volt batteries suitable for caravan, motor-home, camper-trailer, RV, horse float, holiday house, off grid home and all solar installations.

These are our standard battery we use for caravan and motorhome installations – they are a reasonable price but have proven to be a very reliable performer.

In the last 5 years we have only ever replaced one battery (and we believe it may have been user error – but we replaced it anyway).

Standard N70 sizing – always easy to get replacements – if required.

AGM – Absorbed Glass Mat batteries are fast to charge and can be used in any orientation (see the bottom of this description for an in-depth explanation of AGM).

You will need to ensure you have a correct charger to ensure you will have the longest life from your batteries (check with us and we can advise if your charger will be suitable).

To extend the life of AGM batteries is best not to discharge below 50% of the capacity (approx. 11.9 – 12 volts).

Manufacturers Description

The SolarKing Deep Cycle AGM battery is perfect for caravan and RV use. Being deep cycle you are able to run the battery down much lower than a car battery and the re-charge again without damaging the battery.

AGM – Absorbed Glass Mat

AGM technology was developed as a sealed lead acid battery for military aircraft, vehicles and UPS to reduce weight and improve reliability.

The acid is absorbed by a very fine fiberglass mat, making the battery spill-proof. This enables shipment without hazardous material restrictions.

AGM has very low internal resistance, is capable to deliver high currents on demand and offers a relatively long service life, even when deep-cycled.

AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead acid type. It stands up well to low temperatures and has a low self-discharge. The leading advantages of AGM are a charge that is up to five times faster than the flooded version, and the ability to deep cycle.

AGM offers a depth-of-discharge of 80 percent; the flooded, on the other hand, is specified at 50 percent DoD (depth of discharge) to attain the same cycle life. The negatives are slightly lower specific energy and higher manufacturing costs that the flooded.

AGM batteries are commonly built to size and are found in high-end vehicles to run power-hungry accessories such as heated seats, steering wheels, mirrors and wind-shields. NASCAR and other auto racing leagues choose AGM products because they are vibration resistant.

AGM is the preferred battery for up scale motorcycles. Being sealed, AGM reduces acid spilling in an accident, lowers the weight for the same performance and allows installation at odd angles.

Because of good performance at cold temperatures, AGM batteries are also used for marine, motor home and robotic applications.

AGM is also making inroads into the start-stop function of cars. The classic flooded type is simply not robust enough and on repeated cycling causes a sharp capacity fade after two years of use.

As with all gelled and sealed units, AGM batteries are sensitive to overcharging. These batteries can be charged to 2.40V/cell (and higher) without problem; however, the float charge should be reduced to between 2.25 and 2.30V/cell (summer temperatures may require lower voltages). Automotive charging systems for flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell), and a direct replacement with a sealed unit could spell trouble by exposing the battery to undue overcharge on a long drive.

A proper AGM compatible 240volt charger should be used to charge from mains power. AGM and other sealed batteries do not like heat and should be installed away from the engine compartment. Manufacturers recommend halting charge if the battery core reaches 49c.

While regular lead acid batteries need a topping charge every six months to prevent the build-up of sulfation, AGM batteries are less prone to this and can sit in storage for longer before a charge becomes necessary.
