Recommend me a battery booster pack for my M

[blueshoe5000]

Can anyone recommend to me a jump start booster pack for my M? I'm looking around but I'm Not sure what spec of battery pack I'd need. Most of them all say suitable for 1.8l engines.

Can anyone recommend one that comes with a 2 or 3 year warranty?

My car is going into storage but want to keep one as a back up
Thanks in advance!

I'd recommend either leaving it connected to an intelligent charger like a ctek or disconnecting the battery rather than trying to deal with the consequences. It's not good for the battery to drain right down.

I have a Car Rover which I had in the car for over 6 months and then let my electric portable 12 volt cooler drain my battery. I figured I was screwed since I had not even checked the Car Rover for over 6 months but gave it a try anyway. My M started up right away on the first turn of the key.

I've got the older version of this and although I've used it more to help others, it's worked a treat!

As others have said though, a charger would be a better option if you have access to a power socket.
