Title: Works perfectly
Review: I have a sports car with a gel cell battery that isn't driven daily. Before I bought this product, the battery would often die and I'd have to jump start it. Several people recommended this product to me and it works great. I use the cigarette lighter attachment with this and leave it connected to my car whenever I'm not driving it. There are lights that indicate that it's on, and whether it's charging or not.--------------------------Update4 years later, I'm still extremely happy with this gel cell battery tender
