about 3 months ago I bought a new Leisure battery from a reputable dealer. I had gone in to buy a lead acid battery as that was the existing unit fitted. When I told the guy at the counter my vehicle,(A 1994 Hymer 544), he told me that as the battery storage was inside the living area that I should have a Gel battery so taking his advice I Shelled out £134 for the gel battery. I used my vehicle for the first time(presently in France) and a knowledgeable told me I should not have a gel battery as it will either knacker my battery charger or the battery as my fitted charger is for lead acid. What think you wise men as they can't both be right.
