YONHANBattery Charger 0-20A 12V/24V LiFePO4 Lead Acid Fully Automatic Battery Maintainer, Car Battery Trickle Charger Automotive w/Battery Repair, Winter Mode, for AGM, STD, Gel, Deep Cycle Batteries

Best charger I’ve owned. Displays the temperature, amps going into battery, voltage of battery during entire charge cycle and led lights indicating percentage of charge. Works great. Also a maintainer after charge. I love it. Great value for the money.

Quick and easy. Works like a charm

Works like a charm. Used it on a 1997 Dodge Ram 1500 truck that rarely gets driven. I have a solar panel in the windshield to keep the battery charged but all of a sudden it stopped working. I tried to start the truck with my jump starter but the battery was too low. It wouldn't even start using my SUV to jump start it. I was looking to buy a new battery (This one is 41/2 yrs old) and decided to try this first. It said it would bring back a dead battery and it did. Charged it overnight and it came back to life. I now use it for our VW camper and the truck both who get little road time. Saved me a new battery and keeps both vehicles us and running.

This battery charger is a lifesaver! It’s fully automatic and works great for maintaining and charging all types of batteries, including LiFePO4, AGM, and deep-cycle batteries. The battery repair function is a fantastic feature that helped restore an old battery I thought was dead. I also love the winter mode, which ensures reliable charging even in colder temperatures. The LCD display is clear and easy to read, making it simple to monitor the charging process. It’s well-built, user-friendly, and a must-have for anyone needing a reliable trickle charger. Highly recommended!

This is the Best battery charger I have ever had. I have been working on cars and trucks for 50 years. This charger is my 3rd and all are still working Great. It keeps my fleet antique vehicles going.

Had a van down for like a year, so the battery was dead completely. I love this product bc i know I had a damage cell but this product seem to fix that issue and charged my battery. No issues what so ever at this point. I recommend!

Good quality product. Charge fast. Very light. The display shows what it should. Easy to use. Too bad that doesn't works as a jump starter.If you only want a charger, this is good stuff.

The repair mode saved me. I had accidentally turned the rear interior light on when moving a bulky item into the back seat of my Sonata. Didn’t notice it, so when I went to use the car a few days later the battery was completely dead. It checked at 5 volts, so I knew there was a potential for damage.I have one of those small boosters which always work for others I help. I completely drained it in minutes just connecting it to the dead battery. I used to have the big roll out charger and booster. Now in a condo, space is a premium. Everything has to be tucked away in a spot somewhere.This charger is the real deal. It did the repair in hours and then charged the battery to top voltage. It is small and unexpectedly light compared to the heavy units that used copper wound transformers for decades. It doesn’t throw heat and has one button operation thanks to the use of a microprocessor.It is also highly versatile, being able to charge 12 and 24 volt batteries. Great for home backup systems using the latest in battery technology.
