Leisure battery - rotten eggs

[RobPeel]

Hi Funsters,
Our Numax DC25MF 105Ah battery was new four years ago. It had a 3 year warranty. Stood most of last year with just a solar panel to maintain. Given up the ghost now <12v holding. Is this reasonable time for a leisure battery to last?Any other recommendations - we don't do much wild camping - mainly on hookup, although we'll be avoiding large C&MC sites when we are eventually allowed out? Cheers all.

If your title means it is smelling, it wants getting out fast before it blows.

Pull the fuses from charging sources and ventilate.

That battery is just a basic wet cell one I think. Given your usage pattern replacing it for another exactly the same would be easy and not too expensive, they are around £100.

As you only have a single battery it might have been heavily discharged a few times when you did use it off grid. This will have shortened its life a bit. £25 per year for a battery isn't too bad.

Thanks all. Took it out as soon as smell started couple of weeks ago - if only to establish whether it was leisure or starter battery. Connected it to an Optimate to try to resuscitate, but simply loses charge overnight. Yes, thanks, have a quote around £104 from Batteryfactory to replace. Thanks for comments.
regards,

Rob

My Numax batteries are about 7 yes old. I think that they have done very well but I have never let them get down to 50% discharge. Agree with the above comments - you may want to check your charger and charging regime when you fit a new one.

The smell of rotten eggs suggest that the battery was overheating whilst being charged, so before you fit a new battery it may be wise to get the charging system checked out, otherwise the new battery may get damaged.

My Varta batteries are now 4 years old, they have had everything done to them that you shouldn't, several times. Still show 12.7v after 2 or 3 weeks standing without EHU.

Might be worth looking at Tayna Batteries. They seem to be a tad cheaper .

Thanks again all. Will check (over) charging system.
