Yes - I am using the pager charge value reader. I suspect you're right with the different charge reading.
My Eneloops are pretty new - have been charged/used probably 2x so far, so perhaps they'll get better with time. Am using a Lacrosse charger - on the recharge, it charged 600mA, or 1/3rd of the putative 2000mA value - this was very disappointing, given only 2 weeks in a pager, which should be a very low-drain device.
