    Both are perfectly good plans.

    Though "gel" can bite you, if your chargers ( solar, mains, alternator ) are not configured for gel you won't get the best out of gel and it will probably die prematurely.

    A pair of new wet batteries might be the best option.

    Search on here for gel battery by Jaws - a good write up on his professional experience with gel cells.

    This might depend on your charging system. I'd prefer lead acid to gel, as they are much cheaper, so you can have much more storage for the same price.

    I think they have to be the same type and one being a year should be OK if its still in good order, I put 2 lead acids in my Hobby and now leave the Genny at home:thumb:

    In my last caravan I had an Optima US battery and I do wish I had gone for these again though, they charge much quicker and hold full power for longer, would recomend these if you can afford to buy them at £210 each on ebay

    Maintenance-free are the ones the can't add water to, even when they need it. But they are basically the same. Maintenance free ones do have extra bits to cope with the produced gas, but have lower charge ratings as it can only cope with a bit of gas at a time.

    I had to buy one in a hurry ( the ferry was nearly leaving ) but I hate them, it's a way of selling more batteries in my opinion.

    Good old inspection covers tell you a lot about what is going on. Acid goes down quickly and your charger could be faulty. A gently fizzing battery is a happy battery.

    Ah. We just have a trap door in the floor. I can see the attraction of sealed for you. This sealed one is now over 2 years old but whether it will outlast the original German one that made it to 8 is debatable.

    I have near enough the same van as you but mine came with 2 gel leisure batteries already installed, one under each seat. After a cock-up by the dealer who installed a solar regulator that would not work properly with gel batteries, I had them swapped for lead-acid. One bonus was that you could then get a 110Ah lead-acid battery to fit in the same space as the original 80Ah gel one. :thumb:

    If you do decide to swap for lead-acid batteries, make sure they are vented (the vent tubes for mine go out through the same gap as the starter battery under the floor). Also that the battery charger and solar regulator are switched to lead-acid settings.
