Batteries getting cooked,help!

My friend has an EBL 101 control in his Dethleffs and his batteries are very hot,does anyone know where the nearest specialist/dealer is to Calpe where he can get it checked? They have been here for around a week on hook-up but the control is still showing a high charging current,they are new batteries just replaced in May.Van is still under warranty but the supplying dealer wants it checked by a company here in Spain,before they will take any action.

Best to turn off the charger to stop possibly over charging the batteries, then when the voltage drops below 12v turn it on again for a while. This should work till they get someone to test it out for them. Batteries do get warm when charging but this does sound like a charger fault.

Hi,

tel.0034/(0)965 26 24 56

a Dethleff dealer from my list of Spainish Dethleff dealers, I think it lies north of Alicante so should be easy to drive to.

Hi,

Batteries get very hot when one of the cells fail. With a duff cell the voltage never gets up to the point where the charger thinks the battery is full, 14 odd volts, so the charger keeps on going and boils the battery dry.

Cheers
Bill

Might be an idea to check the battery charge settings switch on the elektroblok,which could cause over voltage if set incorrectly,it is blei saure for lead acid batteries and blei gel for gel type batteries.No.12 on the diagram below.

Thanks for all the advice,I was a maintenance electrician in my previous life and do know a bit about batteries.The only batteries I experienced that got hot under charge were traction batteries on forklifts,due to the high current over a short time.

I do find that the KERS batteries very get hot under normal driving conditions but as I have yet to see an MH in a Formula One race I don't think that is your problem
