I thought mine was having a similar issue and stopped using it months ago, but it turns out I may have been wrong. Mine would say 4.20 on the display but when I checked them with my meter they always read 4.07. I just got it out of my storage unit a few weeks ago, along with my meter, and for kicks I decided to check a fresh set of batteries out of my Xtar MC2, and those also read 4.07. I have made alot of negative comments about the D2 but it might actually be my cheap multimeter having too much resistance on the leads and reading everything incorrectly. Ive been using the D2 again for a couple weeks now and it seems to be doing fine. Which reminds me, I gotta go check my LG's now!

I get wonky readings on all cheap meters, but especially with the cheap leads they come with. Cheap meter/lead combos tend to read fairly well above 24 volts, but I've never had luck with them in our uses. I've returned some 6 cheap meters (Klein from HD, Southwire from Lowe's, and something from AutoZone) because there was just too much resistance inside the meter.

My old B&K (20-30 years old) agreed with my d4 about battery voltage within .02 volts, so I think it's golden, and I suspect any actually Nitecore charger with a voltage display would be very similar.

OP said batteries were charging to 80-85%. Does this mean a particular voltage?

Yeah this has me wondering now if Ive biased a couple of the guitar pedals Ive built wrong now.. Biasing the voltage is really important in fuzz pedals so maybe this is why I dont like the way they sound. You basically have to set a trim pot in front of one of the transistors to 4.5v, and this falls well in the range that my meter is a little 'screwy'. If my meter reads a proper 4.2v 18650 as 4.02v, then that means Im sending way too much voltage to that tranny. Shouldve just bought a Fluke but the one I have was free from an IT job I had a few years ago so I just assumed it was ok being my first multimeter.
