    Angry Battery Tenders

    I have been using Battery Tenders for five Years with no problems. Recently, I have had three Batteries go bad. They seem to be boiling the water out of supposedly sealed Batteries. Has anyone else had this problem?
    My Mechanic just told me about Battery Minders. Does anyone have experience with them?

    What brand have you been using that caused this problem?

    That shouldn't be happening with good, proper battery maintenance.

    The BMW model - current and immediately prior versions - has served me well for almost ten years on many cars, whether BMW's of any age, Lamborghini's, Honda's, etc.

    FWIW - there are some battery tenders that are not reliable, or do not provide the needed cycles, or don't restart properly after power failures or simply fail. I've had a few experiences with them - including a couple of brands commonly used and praised. I've never had any such problems with the BMW models.

    I would highly recommend CTEK chargers, all my cars are kept on CTEK chargers when not in use. One of my batteries is 15 years old and still works flawlessly thanks to my CTEK charger.

    Yes, the companies chargers are used extensively and satisfactorily for many. I've had unfortunate results with two of five.
    Maybe just life's odds ...
