Reviving this thread because it’s still relevant. It seems that this is the most commonly available charger in my area. It’s packaged with 4 AA’s everywhere from Costco to independent battery stores. I just bought it with 4 regular Eneloops.
I charged a single battery and it terminated at 1.45 volts. I then charged 4 batteries and it terminated at 1.42 volts. These batteries are in regular rotation and my Liitokala Lii500 normally charges then to about 1.5 to 1.51 volts.
