I bought one of these over a year ago based on a car enthusiast's recommendation. It is easy to use and still working well.

'Nutrend, a subsidiary of Newegg.com, is a leading online retailer of specialized automotive products.'
I have one of these maintainers that worked well for 5 years. Failed right after the warranty expired. WTH, does it have a timer inside?

Can confirm this item works great! I have it attached to my backup sump-pump battery, keeps it at a nice 13.1v. The built-in battery maintainer (built into the control panel/unit) for the backup pump *sucks*, so I connected this in parallel and it "plays nice" with the control panel (they don't interfere with one another).
I think the built-in maintainer never sees a voltage drop, so it never tries to charge the battery,

Also, you can pretty much use any 12v AC adapter to make your own battery tender.
