Our marine batteries - perfect for engine starting and service load - are all of the AGM (absorbed glass mat) construction.  This means that they can be installed upright, on a side or end without affecting their performance, a bonus when considering the limited space available on board.  As well as convenient, these batteries are far safer than their wet/flooded counterparts.  During everyday use, conventional lead acid batteries will emit hydrogen, this odourless gas can build up in enclosed spaces resulting in a severe risk of fire & explosion.  Our Red Flash Deep Cycle and High Rate batteries reabsorb the gases and are therefore a much safer option.

Please note that all batteries weighing over 25kgs will be delivered on a pallet so please ensure that you have the facility to either receive a pallet or have sufficient help to lift the battery.

Please see our Gel vs AGM battery guide.

Red Flash Deep Cycle Batteries The Red Flash range of Deep Cycle batteries is an economical range of deep cycle batteries ideal for marine applications as well as for leisure applications such as motorhomes, caravans etc. We also recommend these batteries for solar and agricultural use. Red Flash High Rate Engine Start & Winch Batteries Our Red Flash High Rate range of batteries have been designed to provide high energy discharge from as small a package as the technology allows. As they are manufactured using AGM (absorbed glass mat) technology where the acid electrolyte is contained within an absorbent medium between the plates, the batteries can be installed on their side or end, allowing then to fit into the most difficult of spaces. Not only are they powerful, but these batteries are safe as, unlike their wet (flooded) counterparts, the gases are re-absorbed during recharge and therefore minimise the build-up of hydrogen in enclosed spaces.
