Another battery question and all was w (1 Viewer)

[stringa]

hi
I've had my motorhome for three years now, a 20 year old wayfarer, as I was giving her a clean I noticed that my hab battery wasn't working so I switched to my main battery and all was well, then it dawned on me that the last couple of trips away the hab battery wasn't working then either, I thought nothing of it at the time as I new I'd be using campsite mains.......along pops a neighbor and he suggested taking it out and charging it....so I did ......to my horror it was flat with no sign of coming back to life, not knowing much about batteries but I thought the alternator would charge up the battery as I drove......what did I do wrong to cause it to drain flat, it was ok when I purchased the van, any help would be appreciated.

Thanks

I suspect that the hab battery is Knackered. Check the voltage

Unfortunately they don't last forever so it's probably just old and knackered, there should be a date on it somewhere.

You've had the van for 3 years but how old was the battery then ?

4 to 5 years is about the life expectancy for a leisure battery.

Chances are you did nothing wrong, just the battery come to the end of its useful life.

Contrary to what folks on here say ,you can sometimes bring them back to life , but obviously not like it was , if you get one of the smart battery chargers , sometimes have them at Lidl or Aldi and get some jump leads from your dud to a good battery and connect your charger to this it will sometimes charge them up, I do this all the time with batterys on electric fences, and even on some of my old tractors .
Edit this is on batterys that other people have chucked out as no good.

Cheers for that chaps, it didn't dawn on me how old the battery was so it's time for a new one.

Hi there my local garage told me when my battery went almost flat,to leave it on trickel charge for a couple of days and said if the battery reading goes up to more than 60% it could be OK. But it not he has a charging unit that will revamp the battery.
