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

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.

i keep this on my car trailer in the trickle function. battery is always hot and ready to go. works great for stuff around the house. very light. can restore completely dead battery's. bright led screen easy to read. smart charger so it switches modes with out have to go change it. clamps are very strong and do not easily pop off. cord is a little short for my preference.

A cool little charger; the instructions are actually clear and relatively easy to understand. This device provides a significant amount of information as it charges. Good value for the price.

Why did you pick this product vs others?:A must have in your car. My car battery reached its warranty limit and wouldn't you know it, my car wouldn't start. Got this baby and you know what, it recharged my out of warranty battery. I'm still running my car on my same battery now for over two years. Found out about this product from a friend and it worked so wonderfully that I told a co-worker about it and he bought one! It even fixes your battery acid levels! Ladies and gents too, buy this product and save yourself some money!

The media could not be loaded. Maaan, I didn’t know this charger would charge my battery THIS fast! It usually takes most of the day, to charge up. When I say within 4 minutes from 40%, it jumped to 80%…. You definitely need to get you one of these!Pros:1. Does not get hot fast, during charging, because of the built-in fan that’s inside, to help keep the innards cool.2. It’s quiet. It’s not as loud as it sounds in my video lol3. The cool feature, that shows you to set it to what type of battery is being charged. These types include:Standard vehicle batteries: just your normal car or truck battery.AGM A.K.A. Absorbed Glass-Mat (for those who have a sound system, or have an RV, or one of those popular diy custom mobile living builds, or just want a better performing battery in general)Motorcycle batteriesGel batteriesWet batteries4. Battery Repair Mode: for those batteries that seem to not want to give much life anymore.5. Fast charging: this battery charger, has the ability to charge at a faster rate than a normal vehicle battery charger, so there’s less wait time, which enables you to get back on the road quicker than usual, and/or back to whatever project you’re using any of these batteries for, quicker than usual.6. Saved this for last, the build quality. It’s not that weird, thin, highly delicate plastic, like some electronic projects are built with. That’s an automatic plus for me. Pretty durable, and as long as you properly take care of it, it’ll continue to be for years to come.7. BONUS POINTS! It’s versatile in usage. It’s not made to only charge one type of vehicle battery, but several types. That can come in handy.Cons: The cord is short. So if you’re looking to charge it directly from wherever the battery is fastened up to, you’ll have to use a heavy duty extension cord. Or, to play it extra safe(which I highly recommend), remove the battery from whatever it’s fastened up to, and bring it to the area you have the charger hooked up to. This way, the battery can safely charge, being isolated from other things. It’s the safest way to go.Overall: I’d recommend this charger to anyone, despite the short length of the cord. That’s something that can actually be worked around. This is overall, a pretty decent charger so far, and pretty handy.Now, if they had a wireless version of this, where I can charge it and it be mobile for on-the-go situations, I’d definitely get 3 backups! Officially, I’d purchase another one of these, as a spare. Because you just never know. You may have to charge more than one battery at a time, to help speed things along.😎

Very nice as far as I can tell. Used it to charge, then later recondition my 5 year old battery. Both functions seem to work great. Nice controls and display to let you know what it is doing. It is holding a good charge and probably will last another year now. Will now see how well it works in trickle charge mode on my battery backup for the sump pump.

Bought this charger to replace a 30 year old charger that finally bit the dust. The new technology in this charger is amazing! The bright digital screen informs me of so much about the battery’s health, as well as the status of the charging. It’s built well and does an excellent job. Surprisingly compact and easy to store. Did not buy it to revive a dead battery, only to top off the battery because my car is only driven short distances a couple of times a week. Highly recommend!!!

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.
