good old fashioned quality

best darn charger I have ever owned and I used a good napa charger for many years, but they just are not what they used to be. this charger from WM allows me to control how fast it is charging and tells me the percentage of the battery charge. it also will not charge a bad battery, which is a safety mechanism that may prevent the battery from exploding, which is a very real possibility. I liked them so much that best darn charger I have ever owned. and I used a very good napa charger for many years, but they just are not what they used to be. this charger from WM allows me to choose how fast to charge it ,and it has a safety mechanism that prevents it from charging a bad battery, thus reducing the chance of exploding (it does happen). I liked it so much (I did not buy the company) but I did buy 4 of them!

Lightweight 15Amp Battery charger

I am very happy with this Schumacher battery charger. It is light weight and easy to carry with the built in handle. The cables and battery clips are of good quality, and it is rated for 15 amps fast charging. I have noticed in the reviews that some of them don't work correctly and damage batteries by overcharging. These reported failures look to be "infant mortality" kind of thing that electronic products typically have. I checked my unit by putting it on my unused car's battery. It started automatically at the 15 amp setting and when I came back a couple of hours later it had progressed through to the maintenance/de-sulfation mode with the green LED lighted. This unit is NOT a booster pack though it looks like one, and it cannot assist with starting current.

I have only used this little charger a couple of times. So far it's been fantastic! You can set it up on the battery and forget it, it automatically switches to maintain mode when charged. It's not huge but it's fine for me. Extremely easy to use. Long cords/cables.
