I've had a good run out of supercharge and they are very
well regarded in the boating community.
Unlike other brands that market a specific 4WD battery, that is just a marine battery with a different colour case and an extra $20 on the price.
supercharge just market marine batteries , which are a rugged construction battery.
The supercharge gold marine, is the sealed version and has glass mats between the plates like any good rugged construction battery.
the ting with the supercharge gold marine is that even though it is a sealed battery ..... the vent valves can be unscrewed and the electrolite topped up.
This voids warranty ..... but after you are out of warranty you have some thing you can do if the battery gets over charged and electrolite gets low.
These sealed marine batteries offer most of the advantages of AGM without the poor temperature tollerance and charge limitations
