Recommendation for Battery Maintainer

I recently got a backup car I will not be using often. I have read reviews of battery maintainers and read that they frequently fail, or improperly keep charging continuously, destroying the battery. Does anyone have experience with a brand that has worked well for them? Thanks!

    I have a Battery Tender Plus that was replaced four times throughout its ten year warranty, so I can definitely relate to the "frequently fail" thing, but it's never overcharged my battery. I'd probably go with a CTek, they seem to be well regarded.

    I really like the Duracell DRMC4A. I have a few of these, and one is about seven years old now. It works very well to maintain and to charge, and will typically provide a full charge, even on large batteries, in about 12-18 hours. These can be used via clamps for temporary applications or with installed ringlets for more permanent applications.

    I bought the cheapest ones I could find at Walmart. About $12 each. Batteries on both cars seem fine. None went dead or blew up.

    CTEK MXS 5.0. I've used it on my Club Sport for several years.

    My Battery Tender Plus is going on 14 years, no problems.
