AGM battery replacement.

[SwissBob]

Battery under seat is marked 80AH AGM. Cannot see a make but there is a sticker with dimensions: 350mm length by 167mm deep by 179mm high. Also a date 2012.

I know the seat has to come out to replace the battery but I’d rather not do it until I have a new one ready. I know there is no room for a second battery but there is space under the other seat and a connecting pipe for running cables.

It’s the height that is causing me headaches. I can’t find anything that short.

Any ideas knowledgable ones?

There's a range of leisure batteries that are 353mm x 175mm x 190mm high. Is that close enough?

I would look for wet lead acid or Gel before replacing with another AGM.
Even some major car manufacturers are abandoning AGM on reliability and lifespan problems.

And there was me thinking that AGM was better than gel. Reading up I see your point.

Would wet lead acid be the calcium ones? I did see a couple that would almost fit.

There is a large metal plate that may be hiding a cm or so but it looks very tight from what I can see.

I think I'll just have to get the old one out before I order. Several places around here (mid West France) where I can pick one up from stock so not too bad.

Actually, looking at the dimensions diagram, although it is very simplistic, it does appear to show the box size without terminals. If that is the case then these low height ones would fit.

Off to Spain next week so I'm putting it off until we get back. Current battery hasn't failed, it's just quite old at 6 years.

If your AGM's are 6 you are lucky, mine failed in a year, there have been similar stories in the forum I wouldn't risk AGM again. Gel or regular Lead-acid should give you another 6 years

Advice taken .

I'm going on the date of manufacture on the battery 2013 but I guess it might not have been used immediately from 2013.

Previous owner says it's fine but I've had trouble with that sort of thing before

 

[jezport]

We are over 3 years with our Duracell AGMs.They are still fine.

 

[Gaston aires]

Our AGM,s are still fine after 4 years. The-wrong charging cycles are the problem. Also if you fit the lead acid type you need to change the charge cycles. Our Adria twin handbook says DO NOT fit lead acid type. You should check this out.

Hi SwissBob

Our gels are 350x170x180tall that is Exide ES900 that they use to call "Hymer fit" because of the low height, same size as yours

Not in my case, the charger was dedicated AGM. We're heavy users and they just got worse over time. These were Banners.

Thanks - the Eriba FT 580 is really just a rebadged Hymer so that makes sense.

Specs on battery sites = 353 X 175 X 190 high. I'm sure the length and depth will be ok but still concerned about the height

Yes mine are 190 actually must get a new tape measure, if it's an Eriba I am pretty sure they would be OK, as you say really a Hymer.

Yes. The older, cheaper technology is lead-antimony, which gases and loses liquid during the whole of the charging process. Lead-calcium is a 'modern' development (ie 1950s) that doesn't gas and lose liquid except when over-charging. They often have no method of topping up the liquid, and are called 'maintenance-free'. If you use a smart charger you won't overcharge them.
