Keeping the car inside for winter

[avalanche]

Hi guys, I park my car inside my garage for winter and take it out for a spin now and then when roads are dry , I had a battery issue last year probably because the battery was not charge often enough, I had to replace it in spring time. Do you have suggestion for keeping the battery alive trough out the winter. I bought and intelligent charger this year that I hope will do the job, but don't know if I should hook it up directly on the battery or on the under hood pols . Thanks for your help

Under the hood is more convenient.

Thank you for your help, I will try it under the hood, I notice on the charger meter that the car shuts down everything electrical after a few minutes and charger stops at the same time . Don't know if the charger will restart automatically when needed . Something to find out ?

The BMW manual says all charging should be done under the hood. Anytime the car is not used for a week or more it wants to be on a smart charger. I use the one from BMW, built by Deltran if I remember correctly. It's on continuously for the 5-6 months it's in storage. Still on the original battery. These cars eat batteries if left unattended and they never shut down completely. Don't understand how yours shuts down and stops charging. Something not right there.

Ignorance is bliss. Cleaned and covered my 2008 135i several weeks ago in preparation for joint surgery. Sat that way for four weeks (w/no charger), started right up (orig battery).
