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

This product did not disappoint at all. It was an absolute life saver when my car battery unexpectedly died. Within just 15-20 minutes, it had my battery fully charged and ready to go. Super easy to use, compact, and incredibly effective. The cord is not super long, but that wasn't an issue since I planned on using an extension cord anyways! I highly recommend keeping on of these on hand - especially during the summer months or for emergencies. Totally worth it!

What I ordered,very bright can see read out in the sun pretty easy witch is nice.works great.

With either 12V or 24V, you can configure 6, 8, or 12V batteries. I did just that on 9, 8V batteries that went dead after a couple years of sitting. They would not take a charge, and I have smart chargers. This unit has repair feature, and it totally works. This thing just saved me $1000. I also used it on an expensive Prius 12V battery and saved that one too. I plan to use it on several batteries that aren’t that old, but won’t take a charge (and last)

Worked like a champ. Great price!

I couldn’t be more impressed with the YONHAN Battery Charger 0-20A! This is hands down one of the most reliable and user-friendly battery chargers I’ve owned. It works seamlessly with both 12V and 24V batteries.The fully automatic features make charging effortless – just hook it up, and it detects the battery type and condition on its own.It’s built well, easy to read with the digital display, and the trickle charge/maintenance mode gives me peace of mind when leaving a vehicle parked for long periods.Highly recommended for anyone who wants a dependable, high-performance battery charger with advanced features at a great price. ⭐️

Worked on my lead acid and my Lif4pro batteries with no problems. Remember to hook up the battery first before plugging in the charger so it can ID what type of battery you are charging.

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.

Performs as advertised. Quality built. Very thorough charging process.
