Agree 100%. I bought the BMW one from Garry, but it's just a Deltran with a BMW logo. One dead battery replaced after 8-9 months (goodwill) was enough for me to throw in the towel.

I have a 4 step battery tender that I'm using right now for my tennis ball machine and it works great I just haven't used it yet for my car since I don't have any battery problem.

that's the one i got, and i plug in for two days now, is it ok if i keep it plugged it?
For anyone who is on the fence, a $45 charger sure beats $400+ for a BMW battery!

My Alternator was Not a problem at all and it is healthy.
They tested it every time they worked on a battery.
BMW assist and Nav and other crap keeps draining battery even if the car is locked. My commute is very less and many times I ride motorcycle to work.
I keep it hooked to battery tender. There are 2 lights, Green and Red, Red means it is charging, green means it is storage charging. Switch is automatic.

Guys, is a battery TENDER the same thing as a battery charger? If so, then I am on the right track.
I have always used a battery charger that has trickle charge and OFF when battery is full. When ever I get a chance I just charge the battery and in all my previous cars, replacing the battery has been a rare thing. Remember selling a 5year old 320i with its original battery.
anyway last month for some UNKNOWN reason, when I started the car I got a warning message. It claimed that something has discharged the battery excessively. I could not get my head around what it was and also the the message system is rubbish.
Needless to say I charged the car but still got the message. This went on for 3 times. Finally in the evening, I removed the terminals and left the car over night charging. Problem seemed to have gone. I suspect it was either the SAT NAV DVD or the BMW ONline not switching off despite me locking the car.
I too would agree with everyone here, get a battery charger with trickle charge (ie slow charge) with function to use on sealed batteries and use it as frequent as possible. It won't do any harm.
cheers
