Question battery tender

Hi, I bought a battery tender and I hooked it on last night. The monitoring light on the charger went from "red" to "green" overnight. I would think it's from "charging" to "charging completed". This morning I started my engine; then, I get a warning saying "Increased battery discharge". Yes, it is "Increased". Center console message says "Battery discharging while stopped, electrical devices were temporarily switched off".

Why is this happening? Should I worry about this warning?
