OK so read many posts about cahrging batteries etc and get the concept, and do everything right in terms of keep our leisure battery charged, however my question is this

We have a Adria Altea 542 UK 2008, with no battery charger fitted to the mains control unit. The power is supplied in the van through the main unit with one switch to turn it off and on. We have a battery box fitted and a 110amp battery (for the mover), which when not on EHU powers all the 12 v circuits no problems. Therefore when on EHU and want to charge the battery can i leave the battery connected to the caravan and then connect a ctek type smart charger also to top the battery up and leave it plugged in on mains 230v. All 12v circuits are powder through the mains control units 12v supply when the battery is not connected. We knew the van did not have a charger as alot of adria dont. Its not a problem just more of a query.

Much appreciated

Are you sure you haven't got a transformer / charger as one unit .
To check if you run the lights off the battery for a short time and then switch on the mains , if the lights get slightly brighter you have a transformer / charger ., meaning you won't need a seperate charger .

Wizard,

No definitely no charger, as the Adria caravans were designed not to run with a battery. With no battey attached we have 12v supply from the 230v mains unit and all is well, and likewise when no EHU is available (like when on storage site) with the battery connected we have 12v supply. The dealer also highlighted the fact of no charger being fitted. So therefore when on site with EHU we normally disconnect the battery as dont need it until leaving when we need the mover. I have a ctek type charger which i connect to the battery the day before leaving and charge the battery. The issue is whether i can leave the battery connected to the caravan and also connect the charger at the same time, or would this push in excess of 12V through the system. As typical systems seem to only connect the battery via 2 leads, and the battery is trickle charged continuously.

much appreciated Chris W

Hi Chris,  my battery voltage can read up to 13.5 volts , so imo if your Ctek charger does not go above this i can't see you having a problem , but i suspect your charger will push more voltage to the battery than 13.5 volts , i would check your charger and see what voltage it charges the battery at . 
You could also see what voltage your 12volt system is getting while on hookup , i expect it's more than 12 volts .
