Nuevo ES 2022 Flat Vehicle Battery Empty Nuevo ES 2022 Flat Vehicle Battery

Post by Dogron Thu May 12, 2022 3:28 pm

Went to my Nuevo yesterday and it wouldn't start - vehicle battery was flat - strange since I'd only been away in it the previous weekend.
Got Britannia Rescue to restart it for me and took it to dealers who put it on charge overnight and have just reported to me that the battery is now 100% functional, and no reason found on the system for the drain.

Their remote monitoring system had showed the battery started losing charge yesterday morning, dropping from 12V down to below 10V in less than an hour, but they have no idea what happened or why.

Dealer recommends I charge the batteries every 1-2 weeks, but my ES is on a storage site with no access to mains. It does have a solar panel.

My (newbie) question is - how often do you guys charge your batteries ?
Do I have to bring it home every two weeks to charge it - by the time I drive from the storage site to home it would have given the batteries a good charge anyway.

I had similar incident a few years back.

Pug would not start, dead battery, Green Flag to the rescue discovered on its last service a short time before the battery terminals had not been tightened up at the Pug main dealers.

What a terrible start to your expected enjoyment in your new van ruined by A/S implementation of what they think is a great setup electrically where recent vans are concerned.
Unless you are on EHU pretty much 24/7 at all times then the questions about flat batteries etc.. just keep on coming from new owners.
What annoys me most is that a setup that just works automatically could easily be fitted but then there wouldn’t be the shiny control panel (stuck on with blue tack by all accounts) that the salesman without a clue can drool over to potential new owners!!

You luckily have a 2014 van, not a 2022!

Dogron, sorry if I sound so negative. There are certainly ways to improve your situation assuming you don’t have an actual fault but I will let the EC700 owners help, I’ve got the earlier EC500 so my info may well be incorrect.

At this time of year your 80W solar panel should be able to keep both batteries fully charged even if the EC700 is not shutdown.  I shutdown my EC700 whenever the van is out of use, including in the summer.  When it is shutdown all your solar charge should go to the vehicle battery so even better.  The leisure battery should be fine without charge for 3 months in storage providing the EC700 is shutdown.  

When your vehicle battery went flat, what state was your leisure battery?

Was a bit panicky at the time so didn't really check, but I don't think it had much charge - none of the "buttons" on the EC700 control panel would work, so couldn't see either battery's charge state.

I was thinking of adopting the strategy you outline i.e. shutdown EC700 when not using van.
I'll also think about buying a battery booster just in case - I was looking at the NOCO Boost Plus GB40 1000A. Anyone use them or have any recommendations?

Thanks for this and your previous reply. I'm told that Sargent are themselves very helpful, so might be giving them a ring if situation continues.
Meanwhile, if there are any EC700 owners who have a similar problem I'd like to know what their solution is.

It sounds to me you have a fault and the dealer is fobbing you off.

One thing to check might be the solar charge shown on the CP.
