Battery Charging Advice Please

[Johnb]

After my last service I was told the battery charger was working but not pushing much juice through. Had I been informed during the service I think I would have asked for a replacement but I missed that boat. The battery is quite new and I wasn't told there were any problems with it and, I presume, its state of charge.

I have an electric Thule Omnistore fitted to the van, with hand crank if the motor fails of course, but would like to think that reliable electrical feed is available.

Simple question for members understanding caravan electrics: I have a CTEK smart charger with "croc. clips" to fix to a battery.

Would there be any problems (if charging issues occur whilst away on EHU) with simply attaching the CTEK to the battery with the provided clips and without changing anything else with the van electrics, plug it in to provide a reliable charge?

Though not claiming to be a specialist in this, I would not risk having both the CTEK and inbuilt charger both together trying to charge the battery .
I suspect it will not do any harm, but as said would not invite it to try.

I would contrive one way or other to overnight just have the CTEK charging. A way might be remove the mains fuse in the inbuilt charger, or pull its mains plug if one is used, or even disconnect the EHU from the van and connect it just to the CTEK. Fortunately I can do this at home should I want to.

Before ever doing it I would research if the inbuilt charger is smart and also test to check it is if faced with concerns I had a charging issue.
