Back on topic - I too consider batteries as almost service items that are too easy to wreck if you are not very careful so I have 3 ordinary Exide 110 Ah "leisure" batteries have so far have lasted over 4 years. That's what I used to do when I lived off grid before going on the mooring with leccy. I just remember going through shed loads of batteries ! I'm very impressed with the Rolls AGM I bought 2nd hand (12v 115ah c20) but it is about £300 new so basically 5 times the price of cheap 110s. Another one I fancy is Odyssey. I do think it's probably right to do cheap 110s from a financial point of view but its just a bit depressing killing them so quickly.

Although they may all be made in the same factory I would never buy ultra-cheap leisure batteries for domestic use. As I said I do buy long established branded ones. I know from my time as a Daganite agent there are a number of ways of reducing the cost of a battery and I get the impression some of the "chandler" or Ebay brands have done just that. Inferior separators, minimal cross section to the actual lead grid, omission of plate pockets, minimal size of intercell links and so on.

Trouble is that short of cutting a whole selection of batteries open one can only guess about what's inside.
Anyone remember Gamages batteries that tended to have half height plates inside a full height case. As we then bought batteries by the number of plates in a cell (e.g. 9 plate battery - always one extra negative one)it was probably not illegal.

I'm not old enough (42). I did read some old cw threads with Gibbo mentioning that he had destructively tested a lot of batteries. Was interesting reading and I think he said a Varta battery was one of the worst for early death. He seemed to reckon the Hawker AGM batts were indestructible I get the same impression from the Rolls AGM but they really are expensive new and its probably possible to kill them anyway. I put Rolls 4000 series in my barge and killed them (one dead cell with 1.05sg in each of the two 6v blocks) in 18 months (off grid Genny charging and never fully charged). Surette did replace them on warranty which I thought was pretty good. I may however have been creative with the description of my charging regime Not totally sure what value a brand has but if it includes an enforceable warranty then that's definitely good.

The previous owner of mine fitted 2x 200Ah Mastervolt gel batteries. 70kg each. That was 10-12 years ago. I knackered one by changing some settings, but before that they still had 270ah between them. They were liveaboards and put 2500 hours on the Genny charging them and rarely plugged into 240v. The Genny was automated and they had a washing machine and incredibly inefficient 240v fridge running on an inverter. The price of them is rather high though.

I have flat batteries.
If I had the space I would use 2v tubular traction batteries. If I had the money I would use lithium. At the moment I have T105's, when I come to replace I'm looking at the equivalent Rolls as they are slightly heavier and at the moment comparable price.

I read on a review somewhere that Master volt produce/put their brand on the best batteries for boats but as lolly gagger says they are rather expensive !!
Rolls are good but from experience I am a little nervous of their tall wet cells.

What I'm nervous of is forking out for "good" batteries while some shit fucker sniggers knowing he's sold brand at 3x it's worth.

Just replaced my leisure batteries today, 2x115ah Yuasa batteries which were £200 the pair. The last ones were ebay cheapies at around £110 the pair, they were dead within about 6 months of living aboard. Hoping these will last a bit longer, but when I'm not cruising I have an online mooring with no EHU so batteries are always going to take a hammering.
