Anyone else keep their rides on battery tenders 24/7?
I am OCD.
And I have the e36, e46, and e85 on tenders constantly since I can't drive them consistently enough as daily drivers.... I am convinced I have had greatly extended battery life as a result. Just curious if others have same setup.

Given the criteria of the title, I don't qualify, but I think you may be right about battery life. The one CTEK7002 spends half of it's time on one of the cars, the other half on the other. Neither car is a DD, or sees a lot of miles/week. Build date of 12/06 on one car; 4/07 on the other. Original batteries.
Seldom do I see less than 3/4 charge on either when I hook it up. One was discharged all the way down (dead, needed a jump) 14 months ago. Ran the CTEK in recondition mode and it's been good to go since. I keep expecting the batteries to go, since they're getting up there in age. But like I said, the charge seems to hold pretty well. |

I learned the hard way. I just took my car out of 3 month storage recently and much to my surprise the battery was dead. No big deal I thought...well when the battery dies in bimmers, it goes into transport mode and automatically turns off power to certain non-critical power options. Resetting this, or turning off the transport mode, requires a special tool...a local bmw shop said they would do it for $50. Anyway...long story short...yes I started using the battery tender to avoid crap like that. I bought a tender pretty cheap off eBay. But I think some folks on here spend near $100 on their tenders.

When not in use... YES.
I have the OEM tender that connects through the cigarette lighter. Easy plug / unplug. |

Same here. When in use i have the battery out of my 88(yes) Camry on it. The Camry hasn't been driven in two years. Stabil in the tank. Zombie wars can happen any second and I'm prepared.

I keep my on 24/7 as the car in hibernation. I usually plug it back on if i don't drive it for a few days or after short trips. I am using a Battery Tender with trickle charge (not need for fancy "BMW" or 'SMART" brand name charger

But, you know, you can't use it on the new Bimmers because it's no longer active without the ignition on.

did you re-program your car so it doesn't overcharge your LTW battery?

4/07 build date on mine, factory battery, and no problems. I make it a point to take it out no less then once every two weeks for a minimum of 30 minutes or more. (Now that I've posted this, it's going to die on me.)

You are seriously due for a battery. I have read about at least ten 06 MR's which needed new batteries in the last 6 mths(mine included). 5-6 years seems to be the magic number.

Battery Tender 24/7 as well...the Harley Road King I own is also on a Battery Tender year round...plugged in after every ride including the fair weather months...I am going on 12 years on that battery...In years past, 3 years was the average expectations for my bikes...I am a BIG believer!

I usually only put it on for a bit during the winter (this winter I didn't hook it up at all over 4-6 weeks it was garaged). Original battery is still going strong on my '07.

I'm keeping an eye on it, it's an H6 size correct? I'll probably throw in a duralast AGM...
