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

Honestly, this is the perfect remedy for those who live in cold weather, skip long in-between driving your vehicle. The charging module is simple to use...1. you simply plug it into an extension cord. 2. Press the "mode" until the light indicator at the bottom is lighted under the correct symbol. 3. Connect the negative and then the positive and off you go...it's that simple! The battery light gauge shows where your battery life stands and where it's currently charging. It even shows the output of power and temperature which is an easy to read and understand. Very simple and high quality! I used it on both my Toyota Tacoma battery. One was a brand new group 35 AMG battery and the other was a group 24f 5 years old regular battery. On the AMG battery, it took about 1.5 hours to charge my battery from 80% percent to 100%! On my other regular battery, it was a little quicker but I doubt that battery could be 100% since it's fairly old but the module was able to figured that out. Awesome product, simple to use and effective!

I have a '99 Ford 7.3L Diesel. The PCM computer went bad from rain that leaked water through the driver's side windshield. I put a new high amp alternator and 2 new AGM batteries - and the truck died 15 miles out - batteries completely dead. Towed it home - hooked this battery charger up and it slowly pulsed a repair, then, in a digital display showed the Volts, the FUL symbol when complete. It took 6 hours, but I was confident that the battery was re-charged. After I install the new PCM, I plan to take it to a shop for a high-end scan. Small enough to keep the charger in the truck.

Initially bought it in case my car battery needed to be recharged. Only reason I gave a four-star was because the product andthe plug cord were much shorter than expected. Will leave a picture so you can appreciate it's dimensions. You will likely need an extension cord to power it on, other than that you're good 🫰🏻

My lights weren't turning on, nothing. My clicker wasn't unlocking the doors. This is my secondary car that I barely drive so the batteries always dying. It actually worked. You plug it up and don't touch the button. Just connect it to your car battery first then to the powered and let it sit until it's fully finished, it will cycle through by itself . It took a couple hours to fully charge. I tried the clicker and it worked, then filled with nerves I went to start my car and it actually worked. What a cool little invention.

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!

After having this 10amp charger for a few months. It's definitely worth 5-stars! It charges the battery, and it's 10amps you can plug it into almost any outlet without worrying about it blowing a fuse.What actually did really impress me which makes it deserve 6 stars is the pulse repair. I honestly thought it was BS but can/have verified it worked! Not by its own led screen but by multimeter and obd scanner (which made me realize it then I double checked with the multimeter)...Super happy and thankful the cheap price didn't coincide with the quality!

This small charger save me from having to dish out a couple hundred bucks, took my battery to Autozone just for them to tell me it was dead and needed to buy a new one, on my way out someone mention get a battery charger with a trickle thing and let it charge, found this one and did its job wonderfully, so great item cheap price and fast delivery, with easy to use instructions

I never leave reviews, but I have to say that this is a must buy! My Jeep Wrangler battery was completely dead. My neighbor has the larger battery charging machines, and he couldn’t get it to start., this little machine has a re-energizing button that will re-charge your entire battery like a new one again, even when it’s completely dead.! Save myself $300 on a brand new battery
