Dead Leisure Battery

[MickNugget]

I stupidly let the leisure batteries discharge a few weeks back. I thought they were ok, as they appeared to take a charge ok.....but since then I've had blown 60amp fuses and this weekend some gas venting from under the passenger seat whilst driving. So....looks like i need to replace. Any recommendations on brand / type of replacement. Also looking for any general advice on whether i can resurect them or are they beyond help?
Thanks

Following on from my last.....i bit the bullet and ordered 2 new Exide AGM batteries https://www.tayna.co.uk/leisure-batteries/campervan/ep800/ . They appear to be working ok, but there are some issues. My question is whether they need coding to the vehicle in the same way as the VW Califormia's need coding to their new leisure batteries.

Thanks in advance for any advice

So....i've finally got everything sorted. I thought I'd share the issue and solution in case anyone else experiences it.

So....after the deep discharge the batteries started emitting a gas/steam. I replaced them. I noticed the 2 60amp fuses had blown so threw 2 of them in also. With ignition on....or 230v plugged in......all works fine. However once the engine is off or it's unplugged.....everything shut down. I tested the batteries and they were showing 12v. So I was really stumped. Ford dealers were no use and they don't know anything beyond a standard transit. I accidentally discovered the system wasn't earthed because when my tester toughed off the bench seat rail, it lit up. So that sent me look for earth's. What I discovered was, there is another 125amp fuse separate to EVERYTHING else. It's in a protective case down the side of the batteries (see pic). It had blown somehow and once replaced, everything worked fine.
Hope this helps anyone having a battery issue
