Got my van out of storage a week ago (inlaws farm building), battery was showing 6 volts which is probably where my problems started. Should have taken it out for the winter but didn't!
I charged it for about 4 days using the vans built in charger. It was then showing about 13 volts. Great I thought, got away with that one!
However, when I come to use the mover, it'll turn a wheel half a turn before it cuts out and wont move. I then have to turn off the handset and start over. The mover is practically useless at the moment. As soon as the motors start to draw the amperage, the relays in control box shut it off. Its as if they wont hold in. On a slight down ward slope the mover will work OK as less current is demanded.
Does it sound like my battery has a dud cell?
Hi Gary, you just might of got yourself a dud battery now. It is said that if the battery goes below about 10 volts then its no good. Have you tried to charge it with one of the new chargers at home that give the battery a slow charge then a boost charge. Just in case you never knew but a 85 amhr is a bit low for using on a mover. Usually the best is around 110 amhr ones. try a different battery and see what happens then. DONT use a car battery though. They are designed in a different way to a leisure battery.
Hope this helps a bit.
Im sure you are right, I don't think I done myself any favours leaving it in the van all winter! Lesson learnt. It was pretty flat, certainly less than 10 volts and Im sure Ive killed it. It was the issue with the mover I was most concerned about as I didn't want that to go wrong but its looking like the battery is causing it to behave the way it does.
Thanks for the tip about the smaller 85amphr ones, il be buying a biggun!
Unfortunately with Leisure Batteries, once they have lost charge they are usually scrap. You can't pick them up again..... sorry but an expensive lesson to you
Our lead acid batteries really, really don't like being left "empty"; it wrecks them as sure as anything can.
So that is what from your description has happened in this case, its not a failed cell it is all six cells.
Dropping below 50% is not wise, but leaving it there is going to be fatal. The rule is don't drain them much and never leave them much short of full.
A quality leisure battery can withstand brief deep drains [up to 50%] much better than a starter type of battery which is designed only to use 20% of its capacity ie never go below 80% full.
You don't need a big battery for a mover, but a sick 100 Ah battery will of course yield more than an equally sick 75 Ah one. As most user batteries are sick they go for bigger batteries rather than buying and looking after a smaller better quality one.
If you don't do off EHU, and can avoid leaving the battery connected during prolonged storage, a starter battery is a cheaper and a suitable alternative to a decent Leisure battery. If you want a decent Leisure battery look for one meeting the EU standard for them, EN 50342 test C20. Look to Banner Energy Bull, Varta Professional, or Exide's Leisure as known examples of compliant batteries.
I've also got a potentially dud battery. It holds enough charge to run the interior lights for about an hour, even when it's been on charge overnight. I borrowed a battery charger, on which the indicator light suggested that the battery wasn't "dead" but even after charging overnight, it was still useless.
Is there a way to revive such a battery?
We left the battery in the caravan over winter - where should we have stored it?
I recently found similar problems when trying to use my mover a couple of weeks ago. I keep the battery on charge over the winter using the 'van's Emperor 3 Stage charger but someone had, unnoticed, switched off the power socket in the garage.
I tried recharging the battery both in the 'van and out on my Halford automatic charger but as soon I attempted to use it went flat again.
I replaced mine with a 115AH leisure battery from local Halfords. A good price of £80.10. Supposedly reduced from £129.99 to £89 and then a further 10% reduction for camping goods when I reserved it on the internet. The battery came ready charged and so I was able to use it immediately and so was not further delayed on setting off.
The Halfords price is currently £89.00 online but I can no longer see a mention of the camping sale. They do smaller sizes too if this battery is too large for your battery box - mine a very "snug" fit. The Halfords website gives dimensions so I measured up first.
