YONHAN Battery Charger 20A 12V 24V LiFePO4 Lead Acid Fully Automatic Battery Maintainer Car Battery Trickle Charger Automotive

I purchased this charger to keep my batteries topped off and maintained, and so far I’ve been very pleased. The build quality feels solid for the price, and setup was straightforward—plug it in, connect the clamps, and it goes right to work. The charging indicator lights are easy to read, so I know exactly where the battery stands in the process. Performance-wise, it charges at a steady rate without overheating, and I’ve noticed my batteries hold their charge better since switching over to this unit. It also has a smart-charging feature that prevents overcharging, which gives me peace of mind when leaving it connected for longer periods. The only minor drawback is that the cables could be a little longer for more flexibility in tight spaces, but that’s not a deal-breaker. Overall, this charger delivers excellent value for the money. It’s dependable, user-friendly, and does exactly what I bought it for. I’d definitely recommend it to anyone needing a reliable battery charger. Read more

Great buy. Easy to use and get the job done right the first time Read more

Best $35 ever spent. I got it on sale which was right on time with my financial situation. I’ll never buy another battery again. I placed it in repair mode for 6 hours then disconnected it to see if my battery was charged. It read full. I have the AGM battery. 3 mechanics wanted me to buy a battery for a cool $250 after checking my check engine light. No big issues until it got cold 6 months later then 3 auto parts stores checked my battery and told me it was bad plus I needed a new one and they could not charge it because the monitor read bad battery. I used my backup jumpstart battery for 3 weeks because the car started sometimes but not all of the time. Luckily I have an older brother. I ordered on Amazon and received it the next morning. I charged my battery still connected in my car on repair mode for 6 hours. No issues so far. Great job guys with this product. It’s affordable and easily obtained through Amazon. Also little to any noise. My hair clippers make more noise than this item. I’m relieved of embarrassment and less stressed after my experience with this product. Thanks! Read more

I bought this battery charger with the hope that it could bring my golf cart batteries back to life enough for the built-in charger to kick in. To my surprise, it worked far better than expected. The charger identified three of my batteries as needing repair. I ran the repair mode for about 10–30 minutes on each battery, and like magic, they were revived. My golf cart is now charging normally through its built-in charger, saving me hundreds of dollars in replacement costs. For such a fairly inexpensive device, the results are impressive. That said, it isn’t perfect. The user interface is clunky — there’s just one button to cycle through all the modes, and the lack of customization feels limiting. My bigger complaint is the manual, which is next to useless. It barely explains how to use the repair function and mostly repeats safety warnings instead of offering real guidance. Still, despite those frustrations, the charger itself works exactly as promised, and that’s what really matters. For the price, it’s hard to beat the value. TL;DR: Brought my golf cart batteries back to life, saving me hundreds. UI and manual are poor, but performance is excellent. Read more

I bought this to use strictly as a charger for my 12v LiPo batteries. However I recently neglected to remove my deep cycle batteries from my Class C motorhome. The chassis battery had suffered from getting sulfated and would not take a charge. I remembered the charger had a repair function so I figured I'd give it a try. Low and behold after running the repair cycle for about 12 hours the charger had repaired and charged the battery that was dead 24 hours ago. This charger is well worth the small investment to keep your batteries charged Read more

excellent product. I have bought 3, One for me, one for my son and one for a member of our car club. I have had mine over a 1.5 and still works great. Read more

Easy to set up and use charger. I like how it displays voltage of battery while charging. Use it to charge airplane batteries. Read more

not as heavy duty as my old one. Battery leads are smaller gauge, cord storage isn't great, and screen is very hard to read since it isn't very bright. Other than that, it has charged batteries well and doesn't take up much space. My previous one was about twice the size and twice as heavy. Newer models aren't always built better. Read more
