Keeping the tow vehicle’s battery healthy

As that's only about 3 weeks, I would think the car battery is not in particularly good condition. When we were away in the MH for 6 weeks in September / October both of ours started fine, despite the drain of alarms over that period. However, previously in May my XTrail had refused to start after only 4 weeks. The battery needed replacing and as I put above there was no problem in September.

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

You may well be right, but until freedom of movement is back I won’t be considering it’s replacement. In its defence, from its last few journeys before it was parked up they were only short trips to the supermarket. 

Our sportage batt would not start the car after 3weeks in the garage ,so Mayday to the rescue ,the car had to be winched out of the garage after the auto box "P" had been released,the Mayday man "advised" it could be an old batt , or it maybe as a lot of modern cars tend to still draw  power when not used, after it was started went to Halfords who tested the batt and said it was fine,but  i noticed the Dash cam was still on  so he thought it may have been that the dash cam is now unplugged when car not used

Since then the batt has not had enough power to start the car  ,so it is now outside the garage ,within easy access to a charger when i next try to use the car

Seems like a few here need to invest in some kind of jump starter pack 😉

Been there, done that. £100 well spent👍🏻

I want to be able to justify buying a jumper pack like these jump start pack 😎

Just go for it!

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
