[Leica] Batteries for M8/M9/MM

[Peter Klein]

What's the current wisdom on third party batteries for the M8 and M9? I 
need to feed my "Henri" Monochrom. All of my original batteries are now 
dead. I have a couple of "Cameron Sino" batteries that I bought a few 
years back. I just ran a couple of charge/discharge cycles on them. 
Hopefully they will still hold a charge. Amazon has many of this brand 
available, plus another that claims to be "." Are these Cameron Sinos 
considered reliable? Any suggestions for batteries available in the U.S.?

Actual Leica 14464 batteries seem to disappear from the marketplace for 
months on end, and when you can find them, they're ~$150 if you're lucky.
