CR2 rechargeable suggestion for camera use

[Aquilasfx]

Hello,
I use a contax G with flash that use 2x CR2 batteries 3.0V
In the past I used it a lot using the green Ultrafire batteries labeled (800mah).
With nice results...
Now It's time to buy new batteries (the old ones are gone, most of them).

There is something new and much durable now in the market?
Can you please suggest me some products? thanks

I use X-tar VP2 to charge them.

So-called "voltage-limited RCR2" are no longer easy to find, and especially for good quality cells.

Newer devices tend not to be designed around 3V CR2 cells.

If both battery compartment size and voltage range are narrowly defined, there may not be a simple or convenient rechargeable solution.
