YONHAN Battery Charger 10-Amp 12V and 24V Fully-Automatic Smart Car Battery Charger, Battery Maintainer Trickle Charger, and Battery Desulfator with Temperature Compensation

This may be small but works in a big way. Worth the money that's for sure. Several said the connection leads are short but to be honest if they were longer it could cause trouble we think that are just right. The size of it is great don't need a big space for storage. It charges your battery quickly and the display showes all you need to know.

I have two of these now. One was accidentally left outside during the winter and was burred under snow for months and, somehow, it still works fine. The screen stopped working after that but it still charges batteries quickly. I bought another when I couldn't find the first one. Both are great chargers for the money.

I love this charger! It is easy to use and works great! It automatically senses the temperature and knows how much amperage to put to a specific battery type and charges pretty fast. I use it on my vehicles, 4 wheelers and motor cycle batteries. And you can not beat the price for this awesome little charger.

After receiving this charger, I put it to work on a tractor battery which had been sitting for nearly a year. The battery was almost dead and would barely illuminate the headlights. I placed the clamps and plugged it into the wall. It immediately read the battery voltage and began a 'repair' cycle. It stayed in repair for a couple of hours and switched over to 'charging' mode. After returning 5 hours later the display read 'OFF' and I started the tractor. Now, 2 months later, the tractor battery is still charged-up and starts the engine. It seems to work fine. The only reason for 4-stars is the cables could be a little longer and the plastic case is could be more robust. Even though it 'feels' cheap, the internals work as promised.

An AMAZING CHARGER and AMAZING VALUE - Works WonderfullyReally happy with this purchase. It fully charged my Dead Sea Doo Battery where my old 12 Volt charger would not bring it back. This is well designed and Well made. The quality is solid, the performance is solid, and for the price that is super solid.

It is of good quality, easy to use, no problem, the power cord may be a little small, but it has no effect after using it for more than 3 years.

This thing works amazing. My alternator and battery died at 5am on the way to work and I lost lights and power steering, but was able to get back home. I ordered this to charge my battery. Once it came in, I hooked my battery up to it, and it was fully charged in under 2 hours. That is pretty nice. So I was like what the hell, let's try this on an 8 year old battery in the barn. It spent a really long time on the auto desulfate function, and when it auto detected it was ready, it fully charged it. I understand that results may vary, but the old battery is just fine now and I have this thing maintaining it. Totally worth money.

This is the greatest. It will jump a battery in a few minutes. It will charge a batter in a few hours. It will repair a battery in a day. I have never seen it fail to get a battery going, and I've had some that there was no hope for and this brought them back to life. Dead of winter, heat of summer, it works. Easy to use, just plug and let run. Everyone should have one of these.
