You can certainly get them outside of the US. There is a fix involving a voltage dropping resistor but because the 1.5 discharge curve is different from the 625 you start getting erroneous readings while the battery is still good. I think the 625 stays at a full 1.35 until it is called home while the 1.5 drops gradually to less than 1 volt. Another fix is an adapter that fit on to the 1.5, lowering the voltage and horizontalizing the discharge rate like a voltage regulator until the host battery reaches 1.35 volts. A final alternative is to use the very cheap 1.4 volt zink oxide batteries. They are close enough to 1.35 that it might not show on the meter but only last 2 months or so from the time you activate them by pulling off the seal and letting air in. You could of course use the 1.5 and calibrate the thing with the ASA dial against your M6 before you go out. The setting should last the whole day. Just remember to test the calibration at both low and high light and settle for dead zero somewhere in the middle. Or calibrate for the brightness you expect to encounter It works for me.
