ATian Smart Battery Charger 12V/20A 24V/10A Automatic Battery Maintainer Auto-Volt Detection ,with LDC Display Tester for Car Motorcycle Lawn Mower AGM GEM Lead Acid Batteries (Red)

I have a 24 volt (2 12volt batteries connected in series) floor scrubber. The charger that came with the scrubber is 4 amps at 24 volts. This charger is 10 amps and charges twice as fast. The display is fantastic in that it shows the battery's voltage and percentage of charge. It shuts off when fully charged and as I understand it would trickle charge after that if left connected. Thumbs up 5 star unit

While the ability to charge 12 volt batteries will benefit most customers, I purchased as there are very few chargers in this small size that will also charge 24 volt sealed batteries, which is what I use in a backup power supply.

I don't like having to switch the battery type to the most common types of batteries used. This should be the default and not the other way around. I never could get this charger to charge a series of golf car batteries equaling 24 volts at 10 amps. It would only charge at 4.5 amps. The charger is light and it works. The cables could easily have been longer. The finish is pretty good. The handle is plenty strong but made for very small hands.

I really don't like it didn't work without plugging it up. It's not worth using it out in public no good without a plug outlet.

Item arrived and it was plugged in to charge boat battery which is what it was purchased for. Worked a little slower than expected but it worked. Stored on shelf early December in garage and not used again until needed on January 29th again to charge boat battery. Went back to check on it the next morning not charging. Boat was needed on January 31st still not charged. Checked on Amazon ,guess what, warranty ran out on January 31. How about that

This battery charger has helped me because I have cars that I don't use much, and the battery gets low. I put it on charge, and it charges the battery, and I can use that vehicle.

I tried it the second day i received it and it worked as stated and was easy to use. It finds voltage so you do not need to pick voltage. Wish that Battery Type was bigger. Also back screen in green and numbers are black which is hard to see in the dark. i use it in engine room and need to shine light on it to see whats happening - wish background was dark and numbers were green LED. Also confused with something, when first connected it shows battery 100% but when charge starts it states Battery is a 10% and goes up as it charges and fan constantly goes on and off, is that normal?

This battery charger it’s a great little battery charger very small I keep it under the seat of my truck don’t take up any room and charges pretty quick to my battery was completely dead I left this battery charger charge my battery and now my battery was reading 12.9 V which is I hooked up another battery charger and that one wouldn’t even charge it how good it was buy this product
