Keeping the tow vehicle’s battery healthy

I haven’t used my vehicle since the government advised everyone to stay at home. This morning thinking that I should start it up, I discovered that the battery didn’t have enough change in it to turn the engine over fast enough.

Luckily, I keep it on my drive along with my caravan. (Bailey unicorn )

 
So after starting to run the mains cable and battery charger out to it, I thought about the caravan parked next to it, with its Truma Solar panel keeping that in tip top condition.

 The Truma controller has two separate battery outputs as it’s suitable for motorhomes. So the simple answer was to temporarily run lead from the unused battery terminals on the controller to my vehicle.

 I know that I am fortunate enough to have them side by side and my tow vehicle has a permanent live accessory socket that I can plug the lead into. But it wouldn’t have been an issue if I had to connect it directly to the battery.


While I’m not using it, I can rest assured that the caravan it’s looking after it.

 And before someone starts on about leaving it connected and damage being done, the Truma controller is a “smart” charger!

With access to 5 cars & a decent set of jump leads, I'm sure I'll be able to move one to another to jump from it 🙄 ..... though the type I linked to could be handy for other things

Mmm, but when away in the MH the other car isn’t with us. 🤔

When we tow the caravan we only take one car with us ... 😏

 My Discovery can run down the battery to the level where one of the computers complains in about four days at the best of times. There are so many things still running when it is "off" that I'm not at all surprised.

As well as the jump leads that almost every Land Rover driver carries I bought myself one of those new-style charge blocks. It will run my tablet for days on end or my girlfriend's 12 volt electric blanket for a lot less time but a lot more brownie points!

There again, my Forester (brand new) went flat in 3 weeks. I blamed all the electronic gadgetry on it. 🤷🏻‍♂️

cant beat the oldies, our Kia Carens 2007 sits on drive for 3 months whilst we were are in Spain, starts first time, we have had the car 10 years and never replaced the battery, always leave in park mode , handbrake off couple of bricks under front wheels, always reverse in so you can get into bonnet easily if something should go wrong, all this keeps the battery charged no problems foot-in-mouth

I think it would be same to assume that Rufs drive is not part of the public highway.

Just a quick update.

Just checked the batteries and both are showing a good state of charge.

At least I know that my vehicle will ready for when I need to use it next without the worry maybe having to jump start it.
