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!

I love how people give thumbs down for honest feedback. Just because it's not a raving review lol

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

I have had 3 of these for a few years now with no issues. Using them for motorcycles and a riding mower. Well worth $11

Which noco do you have? I have the g3500 one and it's super slow. When I measured the current, it was only about 700mA.

I had bought this three years back used it for 1 winter and was dead the next time I went to plug it in. I warranted it lasted 4 months and was dead traced the circuit to problems with a few components on the board with crummy solder. Went with diehard Schumacher clone and have not had a problem yet after two years.

add something expensive for store pickup and cancel it (or wait to expire without picking up)
as soon as order ships. Works even better if you can find a pre-order item

I'm not sure if this deal includes the spring loaded clips that grab onto the terminals of a 12V gel battery. Can anyone please confirm?
