Repair mode on LiitoKala Lii-600 charger

I noticed that all your batteries are Duracell’s. My experience with 12 Duracell batteries was not good at all. After less than 2 years and maybe 5 charges their IR jumped to > 2000mOhm. Couldn’t be charged on most of my chargers and I tossed all but 2 of them since those still charge on a dumb charger and can be used in my low current draw tv remote control.

Edited to say that I have Eneloops from 2011 that still test out as well as Eneloops I bought in 2018, so yes 10 year old batteries can still work well depending on who makes them.
