Mystery battery

[scally]

Has anyone come across a battery like this please. I bought a new van just for me0 and this is the battery in it just connected to a solar panel and 3000 inverter to power a mains fridge. I've never come across one so any help advice would be welcome.

Can I cross connect it to my lead acid engine battery and charger via a split charge relay ? TIA

For some reason I can't load the pictures. But they're yellow,22in long 5in wide and 11in high 12vdc
. Hopefully som4body cab shed some light on it

Likely your picture file size is too large

take a screenshot of the pic to upload a smaller size, i sthere no names or numbers on the battery

They could be 6v batterys they use for hospital back ups that description rings a bell for the batteries linked together the miltary use in helicopters

Before lithiums came on the scene, some used traction batteries that were 6V each, in series or series/parallel. Some even used collections of 2V traction cells. They built them into 12V packs like they do with lithium cells.

Thanks for that here is a top view

Its a 12v telecom agm stand by power supply battery, often used in raking systems. Even victron do them.

That looks like a backup battery likely AGM. Had a similar product once, they can be a handy shape for some lockers since they're thin and tall. Ours were Mastervolt. Odyssey and Victron also common.

If AGM it will need 14.7v to fully charge, but an alternator SCR connection will top it up. AGM need to be regularly charged or will sulphate, so if unknown I would test it's capacity before spending any money.

I think they are best suited for backup over short periods, with regular maintenance regimes, and not deep cycling leisure batteries with haphazard charging..

Can't help with your question, but a battery in the gas locker ?

Yes thats not great at all!!

It does very much look like a Powersafe 12V170F AGM as Raul suggests.

As it's an AGM there shouldn't be any issue in charging it of a split relay. I would also consider putting a battery protector on it as you should never deplete AGMs below 50% of capacity or it damages them.

There will probably be a sticker on the front (the terminal side) of the battery which will confirm what it is but if it's a 170 then that's the Amp hours (so 85 Amp Hours of useable power)

It was like that when I bought it. Am in the process of moving it.

Thanks for all the info. Currently it permanently connected to a solar panel via a controller and a 3000 inverter running a fridge. Methinks there will have to be some changes to the system

Hthanks I probably will, I've never come sacrosanct this battery or controller before it 30 years of self build. What a sad state to be in
