I've seen many threads here regarding the battery draw that is constantly on our cars with all the electronic monitoring, key sensing etc. Especially with winter, here there are times my CTS Coupe sits garaged for a while and I was interested in getting a battery tender. The car lost window positioning once, and although the battery wasn't dead I'm wondering if a weakened state may have caused that because it had been sitting for two weeks. Was looking for any suggested tenders that people may be pleased with, or any "options" I should look for that make them safer/better to use. Thanks in advance.

The original Battery Tender is still one of the best. I use and sell a lot of them. They just redesigned them to meet the Calif regulations and now they consume less power. The Battery Tender plus is the one I would suggest. They have a great warranty also.

There's no need for a battery tender in these cars. The low level computer systems shut off after a few days of sitting (ever wonder why you can't communicate with Onstar after the car is sitting?). You should be able to park for several months without having a low battery.

Really, good to know. I had a 2005 XLR and those would have battery drainage problems all the time. I guess GM/Cadillac learned something and implemented the change in the CTS design. Thanks for the info.

Mine won't go for more than 3 months without charging or running. Been like that since the 2nd winter. Sits in an unheated garage most of the winter and avg temps are below 0*C.
