Do you have a 2 amp capable usb wall charger you could try?
Might not be it but, gotta eliminate the possibilities.
I think you’re assuming I have a basic knowledge about power requirements, amps, volts, etc. I do not lol.
All I know is, while plugged into my MacBook Pro, the charger seemed to work fine with the Nitecore test battery I tried
I know a Nitecore CR123 sized battery wouldn’t need more than 1 amp to charge. especially when the power source is supplying 5v, its stepping down so the current required is even less than 1 amp. Just trying to help
Talk about bad luck, what are the chances of having 2 DOA Sony batteries.
@mcdj: I know Neal ships with a black plastic tape insulator at the negative side (rear end) of his cells.
Did you remove it?
Yeah, it’s kind of strange. I have had li-ions set for years and not read zero when checked.
This is probably the answer.
OMG!!!
Sorry everyone. It was the tape. I had no idea. It’s not mentioned anywhere in what he sent. And like the title says, I’m a noob.
Thanks for all your suggestions. I don’t think I’ve ever encountered so much great real time support on the internets from people in any other forum ever!
Everyone was new once 
Glad it worked out well for you.
That’s the best kind of problems to fix, the one’s that don’t cost a dime to fix.
Glad you got it working. 
Nice that’s it’s sorted , but it may work better when plugged into the mains, computers only supply a certain amount of power , a bit like the xtar vc4 it will not charge at full throttle if limited.
