    Any recommendations for a QUALITY battery tender for my 01 Z3? It will be garaged for much of the winter, and not started at all in December.
    Griots has one that seems to have all the right specs.
    Any tricks in getting them hooked up?

    BMW has there own as well, griots is fine. The main idea is to get one that is a smart charger that monitors how the battery is charged and can turn off when it's charged and on when it needs it. To hook it up I would just put it on the jump posts under the hood.

    I've been using the Schumacher battery tenders that I pick up at Tractor Supply Co. I have four (4) of their units on my own cars, and another three (3) of them for use on custome'rs cars, when required. I have never found their performance to be lacking, and some of the units must be at least ten (>10) years old by now, with a zero percent (0%) failure rate.

    At some point point they went through a redesign, as the three (3) most recently purchased units are much lighter (in weight) than the originals, so time will tell if they are any less durable, or if the technology has advanced that much.

    Historically, I always paid right around $20.00 apiece, but cannot say for certain if the newest ones were still the same, nearly give away price. All include a choice of connection methods, either spring-clamps, or a disconnecting plug can be wired into the car itself.

    You can always pay more for something with fancy brand names, but these economically priced units include all the quality that I need from them!
