Have my leisure batteries had it?

[Christy]

Off grid at the mo at a NT campsite.

Have two leisure batteries, Fully charged before I left home. Solar on roof. At 6:45 the sargent was showing they were at13v.

Went to pub. The only thing on was the three way fridge on gas. Came back two hours later to the sargent saying just 10.7v.

My questions are:

A) is the 13v showing on the sargent in daylight just the rate it is being charged at in sunlight and not the actual charge in the battery

And

B) are my leisure batteries knackered?

I have had van for four years and batteries were in it when purchased.

Also it has 1 amp inverter already fitted which I left on by mistake for a few weeks only to find batteries less than 10v. I know my mistake!

Thanks for any assistance.

Yes

and

Yes - probably, if you have a multimetre you could test their state more accurately by taking the voltage from the battery terminals and doing some checks

Do you mean 1Kw inverter ?

I agree, they are probably goosed. If they go down to 10.7V, if you recharge them straight away, there's a chance they may recover and be OK. But if they've been like that for a few weeks, that's probably finished them. However you've had 4 years out of them, so not too bad.

Thanks folks. That’s a couple of hundred quid then sadly.

Update - managed to get one of the old leisure batteries out and after a bit of research found that they were no longer produced after 2015 so I guess it is a good 8/9 years old! So no wonder!
