Review on RJTEK Smart Battery Charger/Maintainer/Pulse Repair Charger 12V/20A 24V/10A - Fully Automatic with Cable Clamps, Winter Mode - Car, Motorcycle, Lawn Mower and More by Jermaine Rhodes

I bought this because of the multi voltage input (110 and 220). Of course it works. However, how the charging works remains a mystery. Setting the battery type is completely confusing as the charger only allows AGM and Gel settings. So I filled it in, SLA and whatever else you can't select there. Then the current setting also affects the charging mode in an incomprehensible mode, because with the setting of 5A it will not work to charge a regular car battery, you need to choose 20A (or maybe 10A?). It is completely incomprehensible how the "Repair/Maintenance" button works. I never activated it. This guide is a Google Translate guide for Chinese. Can not do anything. The device looks good, but they had to paint it black to commemorate the black magic going on inside. Unfortunately, I'm really looking for an advanced charger in the market that will help me understand the condition of the battery.
