3Works as described, Would like a few more features
By Kevin W
I ordered this battery charger to replace a Die Hard that died. We commonly have to either keep vehicles that are sitting for months at a time on a trickle charge or sometimes jump a vehicle with a dead battery.

This charger does great with everything we hook it to. Some of the settings and displayed feel a little too dumbed-down for my taste.

The main feature that would make this charger a lot better for my use would be charging a battery that is completely dead. Right now, if we want to use this charger on a dead battery, we have to hook a charged battery up to the dead one so that the charger will realized it is hooked up. Once the charger starts the charging cycle, we can unhook the good battery.

Edited....After several months, I have had problems charging some Optima batteries. At times it will stop charging after an hour or so and just blink.

3Charger is smarter than the people who wrote the instructions.

First of all, it works. I've used it to bring one dead battery back to life and right now I'm staying up late baby sitting another dead battery that's connected to this thing.

My problems with this product have to do with useability.

First, the instructions are scatterbrained. The essentialy information you need to use the device is all over the place. I really would have appreciated a single sequential set of instructions followed by the troubleshooting guide. And, the instructions don't seem to tell everything. I had this thing display "OL" in the LED which I assume was "overload", but the little instruction sheet said nothing about this error code.

Second, and much more infuriating, is that the controls are labelled with a font and color combination that is just about unreadable even up close with my reading glasses on and a flashlight on the controls. No, my eyesight isn't that bad! It takes a very special talent to create a pro duct that comes with all kinds of safety warnings, and really looks like you could blow some thing up if you used it wrong, and then makes the control labels almost unreadable. Nice going there people!

5Never a problem
By JoeCool
I have used this for over a year and it works like a charm. It is a little noisy but not bad. I use mine in the garage, so it's not like I'm in there most of the time to hear it. It has worked perfect for about a year now. I love it and am glad I got it!!!
