Help with Motorhome laid up for long term

Looks an interesting little gadget, could save going under the bonnet with the multimeter!

but as a lot of ciggy lighters are ignition live you'd need the ignition on each time you wanted to monitor battery voltage .... so the car would have to 'wake up' each time.

what's the problem with that, turn on the ignition it should read about 12 volts it would be pointless starting the engine unless of course you need to check your alternator is ok then the voltage would go up to about 13.8 volts. The reason I bought it in the first place was that some members were having problems with their caravan fridges due to smart alternators  so while the good lady drives I can monitor all is well we have had it sometime but I've not seen a problem with our present tow car 

12v is nearly flat  should be around 12.7 

I'd have thought that keep waking the car up, opening doors,  would just be helping to flatten the battery ... kind of defeats the object of monitoring it in the first place

How often?

How often ....what? 🤔

'Click & Collect' shopping trip tomorrow, so first time that Tiguan will have been used since 27th March. I've opened the car occasionally to get tools out and wash off the bird droppings, so battery should be OK.

Return trip is around 20 miles and I'll check the oil temperature to ensure that the engine has been thoroughly warmed u[p before switching off. Might take w short detour along a stretch of dual carriageway to open Tig's lungs and assist with warming/charging.

Mileage since return from Spain 7 weeks ago is around 100 in total, including taking caravan to Repair/Service Yard so within spirit of essential travel guidance.

What is the best way to use a trickle charger attached to the cab battery of my 2018 Bailey Advance 76-4? I am purchasing a Bosch C3 charger/trickle charger.

I had thought of plugging it into the 240v sockets in the motorhome and connecting it to the cab battery.  To do this requires the van to be attached to the electric hook-up and the main control panel switched on.  Would this cause any damage to the motorhome electrics?

The alternative is to run an extension cable from the garage and run the charger from this separate independently from the van.

Any thoughts?

first things first.....doesnt a 2018 Bailey Advance charge the cab battery from its on board charger, ie when you plug in a 230v EHU cable?

similarly, doesnt it have a solar panel? and, if so, doesent this charge the cab battery?

if neither of these things is true, then you will need an external charger like the Bosch....i certainly wouldnt be bothering to plug in an EHU and turn the van electrics on (may not be required). 

i would just use an extension from the house/garage to the Bosch.

when all this virus stuff is over, have a look at fitting a Battery Master which wil transfer charge from your leisure battery to your cab battery.

perhaps also a look at a solar panel if the van is residing at home when not in use.

our 100w panel. is geared to charge all batteries and i never need to even think about EHU cables to maintain a healthy charge. 

It missed the last bit  ,will you "need" to check the batt, that will have an effect on it if you turn on ignition, for a few seconds?
