MASTERVOLT AGM BATTERIES
In AGM batteries, the electrolyte (mixture of water and sulphuric acid) is largely absorbed in glass fibre.
This type of battery is entirely maintenance free and there is no gas formation with normal use. Not requiring any ventilation, these batteries can be installed almost anywhere.
Their construction gives a very fast discharge at very high currents so AGM batteries are ideal for systems that require high currents (for instance when starting an engine). The battery poles can be unscrewed and this type of battery can be combined with every standard battery terminal.
