Switched off battery charger by mistake

[Cairngorm]

I inadvertently switched off my leisure battery charger and though it was connected to the electricity. After four days everything stopped working with a dead control panel and showing a flat battery. Realised what I had done and switched on charger and everything now works. Have I damaged the battery with draining it.

You'll have shortened it's life but it might be ok for a while yet ?

Although the battery will often recover its life will be severely shortened. If you rely on your batteries for off grid use probably best to replace them.
I see you have a Frankia so I assume it has Gel batteries they stand a good chance of surviving.

If it went flat in 4 days either the battery has already had it or you had something switched on drawing current.

You might have done them a favour, I often wonder if we should let ours discharge further occasionally to wake them up

ours stay on permanent hook up at home

we have had to change ours roughly every three years anyway, I put it down as a running cost ?

what you might find as we did, if you have more than one battery, one of them might not recover as well and make it look like both have failed

You should get at least 6 years out of a gel more like 10 is the norm.

They only give a couple of years warranty though ??

It might not be as bad as you think. If the battery cutoff switched off before the battery was totally flat, and you didn't leave it discharged for more than a day or two, then it might recover quite well.

I was thinking the battery was totally dead but a Frankia will have an EBL which will shut off at an on load voltage of 10.5v.
Still shouldn't have gone flat in 4 days unless something was left on or battery is duff.

Or he has your quiescent current drain ????

Even with an LCD control panel left on it should be less than 500 ma. Even just an 80a/h Gel should last 18 days without any problems I think Frankia fit a lot bigger battery as standard.

Ok, seems more positive, because it was dead as a dodo. ??

We were living in it for the four days And on the move as well. When not on the move we were plugged into the mains.

In that case then the EBL would have shut down to prevent battery damage, the shut off is 10.5v on load voltage which is nowhere near as flat as 10.5v offload.
Battery should have survived, just don't do it too often.
