Battery Charger/Maintainer - 2006 E85 3.0si

Hello:

Brand new to the group and a new owner of a cherry '06 3.0si.

Winter will be here soon in Ohio and a I will need a battery tender/charger/maintainer. I did a quick forum search and only ran across a thread from 2 years ago. So here we are.

Any recommendations for a winter storage battery maintainer/charger? I looked at the BMW version and it seems the CTEK is the same thing for just a couple dollars less. Also have seen the Battery Tender Deltran versions.

Suggestions?

Phil in Ohio,

I've used the deltran ones but the ctek ones sound good to me.

New here too! I am in NY-Long Island. First BMW! Also a 2006 Z4 3.0si Roadster...low miles, clean history and Carfax, just needs some interior TLC that I am having done over the winter to make it show ready. Probably should look into some kind of battery maintainer as I just replaced a dead one. Still take it out of my garage for a short ride once a week for now. Please let me know how you make out on your end. Lance - Email: LMeschkow@yahoo.com

Do you have any idea how many of these gems (z4 3.0si) were built?
