[Leica] Third party M8/M9 batteries

[Peter Klein]

Can anyone recommend a reliable source for M8/M9 batteries?  The ones I 
have are getting old.  A year ago, I bought two from batteryclerk.com, 
which lasted only about 7 charge/discharge cycles before they both 
failed.  Fortunately, they failed just after--rather than during--my 
recent trip to eastern Washington. They were "Cameron Sino" brand, in 
other words, Chinese knockoffs.

All my other batteries, both Leica and third party, have lasted 5-10 
years.  Yes, ten:  One of my original M8 batteries still works! I just 
want to get a couple more in case one of my current ones bites the dust.
