AGM Batteries
What are AGM Batteries?
AGM batteries are lead acid but unlike in conventional batteries electrolyte is stored in glass matting between the plates. This means the battery is leak-proof and does not vent.
Why Choose an AGM battery?
- The are sealed so they are almost gas free - you can use them inside your car, boat, 4WD, camper or RV.
- They are leak proof - you can mount them on their side.
- Storing the electrolyte in glass matting gives better conductivity, improved vibration resistance and, therefore, potentially longer battery life.
- They charge up to 5 times faster than conventional batteries thanks to lower internal resistance.
- They offer high performance with excellent CCA rating again mainly thanks to lower internal resistance.
- They can be designed to have high cranking power as well as coping with deep discharge so you can choose these where you need blend of cranking and deep cycling.
What about Price?
AGM batteries are a premium product at a premium price. Expect to pay 25-50% over maintenance free batteries for the equivalent power.
In most cases though, the improved performance and greater longevity will mean the cost per day is lower over the life of the battery.

Charging AGM Batteries
It's important to choose the correct charger for your battery - it must have an AGM setting on it as they need to be charged at a sightly lower voltage. The wrong charger will damage your battery.
As with everything you get what you pay for - a quality charger will sense the resistance from battery and modify of charge it gives to try to squeeze as much charge in as possible. Read more about battery chargers here
