The packing says these batteries are "Pre-charged, ready to use".
But when I put them on my SunLabz NiMh charger, they're good for at least an hour, sometimes more, of charging before the charger deems them charged.
Am I missing something?
Doing something wrong?
any charge can deplete eventually, i suppose...?

Exactly, depends upon how long they have been sitting on the shelf.
I think they are charged -- but not fully charged, even when brand new.
And how long does it take the charger to determine the charge state?

I thought they lost charge in storage. This reference says it could be as much as 40% in a month:
Per Percival P. Cassidy:
The package was a dozen AAA batteries.
2 of them were charged up fully within an hour. 2 of them took more like 2-3 hours.Four of them are still on the charger after six+ hours.
Four more are still in the box (charger only takes 8 batteries).
Had a similar experience with the four AAA Eneloops I bought a couple weeks ago.
I am starting to wonder about the charger - although it seems to have behaved normally for the year or so I have been using it on some AA NiMh Energizers.
Could be the charger. I've had too many instances of Eneloops that fail to charge in my Sony chargers. Lost my Eneloop chargers when my basement flooded. I went to the Sony Cycle Energy batteries and IME they are better. They hold a charge longer, and take more charges. None have failed in about 3 years. Better charger too.
That link is to regular NiMH. The Eneloop batteries hold on to their charge much longer, but not forever.
