Duracell - 4 Amp Battery Charger, Maintainer and Reconditioner - Black

Does everything that battery tender does and more. Including having an led screen and better spring clamps.

I’ve had this for a couple of weeks and seems to be working well. Easy hookup, LCD works well in the cold (some don’t). The charge is slow so don’t expect a quick charge. The only real small gripe is that the ring cable to put on the battery is rather short, on my Subaru it won’t reach to come out the grill so I need to pop the hood to attach/detach (might be able to find another route once it warms up).

My car has a short someplace and the battery seems to loose it charge a few days of not driving it. This little tiny device keeps my battery going and hasn't failed me yet!!! So glad I got this and so happy it works amazingly keeping my battery charged!
