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 Ray Richards

I have two batteries that I have charged with it, one is charging but the percentage is changing too quickly. 2% to 70% in 5 minutes on a 5 amp charge. I can't find any other battery at all. Probably due to low voltage. The biggest problem is clamps. Works great above. There is no way to attach it to the battery on the side rail in the car. You have to pull it and connect the bolts to the clamps, even then it's iffy. The plastic around the clamps blocks the attachment.
