Hello Westfalia fans,

Does anyone know where the EHU charger is located in the latest Columbus models? I've noticed that it is charging the AGM batteries at a float voltage of 13.5v. I contacted Varta and other a couple of Varta distributors and all suggest that a float voltage for the Varta AGMs should be 13.4v, and even lower for long term EHU hook up. Ah the joys of AGM batteries! Therefore I am wondering if the charger is configurable...

Thanks
Will

Is 0.1 of a volt so critical? Have you used a test meter to check the voltage at the battery posts, as there's often some panel instrument discrepancy.

I think it should be under the passenger seat.
Thanks, I'll check there, not sure what I'm looking for but hoping I'll recognise it if I see it.

Not usually, but when in long term storage it would ideally be more like 0.2-0.3v lower (so ~13.2v) which is what is recommended by the battery manufactures. See the excellent battery info site here http://www.aandncaravanservices.co.uk/ehu-full-time-yes-or-no.php

Mine's in my drive so I leave the EHU and therefore the charger turned off and just turn it on about once a month to give the batteries a refresher charge if needed after checking their voltage. I don't have any solar or constant drain items (alarm, radio, tracker.... so forth). My current Banner batteries are 6 years old now and still good. (Fingers crossed that they don't die next week).
I guess it's not so convenient if the m/h's away in storage.
