I own two of these. The newer one I got is built a little different and is glitchy vs my older one. I wouldn't buy this again. Go with quality NOCO. I also have other brand of chargers. Battery tender (the bigger one), Aukey, and craftsman?) They are all glitchy. A couple has overcharged my car battery. The old black and decker one is still solid. But the best is NOCO hands down, one of the best!
B&D maintainer caused my Viper's battery to boil over way back in 2006. I vowed never again to B&D, which of course hasn't been particularly difficult.
Guess where the battery is in a Gen 2 Viper: inside the driver's rear wheel well. What a beautiful PITA

My 2 cents, take it or leave it. Just contributing to SD, or I could not post.

the other (completely) different one is the float charger for $9 [harborfreight.com], again no coupon for further discount.
