Review on 🔋 ATian Smart Battery Charger 12V/20A 24V/10A Automatic Battery Maintainer with Auto-Volt Detection, LCD Display Tester for Car Motorcycle Lawn Mower AGM Gel Deep Cycle Lead Acid Batteries (Red) by Clay Ijaz

I tried it the second day I received it and it worked as advertised and was easy to use. It finds the voltage so you don't have to pick the voltage. I wish the battery type was bigger. Also, the back screen is green and the numbers are black, which is difficult to see in the dark. I use it in the engine room and need to light it up to see what's going on - wish the background was dark and the numbers were green LEDs. I'm also confused with something, when I first plug it in it shows 100% battery charge but when charging starts it writes Battery at 10% and goes up while charging and the fan keeps turning on and off off , is this normal?
