I have an Ultrafire WF-139 which cannot be used for charging the 10440's, can I use my Eneloop charger? If not, what is the best charger for them?

you can NOT use an enloop AA or AAA ni-mhy 1.2V type charger to charge a 3.6v type li-ion battery.
you could use a lower rate of li-ion charger, like a nano type.
you could (possibly) fudge up the charger you have with a resister, the max voltage would remain the same, but the charge rate would be lower.
what the specs, its about 250-300ma (capacity) , it should be charged at about 200-300ma Max, for the first 80-90% then down to about 100ma till it gets to 4.20v (+-.05v). unfortunatly most cheap chargers dont properly slow down, making them ok for the higher cap batteries but not so good for these little things.
so any ol 25-100ma li-ion charger would do the job. somebody said use the li-ion coin cell charger as that would be a low enough rate.
( at 25ma it would take all day, at 100 it would take about 4 hours)
and any charger that had a MAX voltage of the 4.2v could be set up with a bit of resistance so it slowed down.
any charger that terminated differentally at the 4.2v but had a too high max voltage could NOT be adapted to charging the lower rate.

Nevermind, the spacer I linked is not for 10440 cells . . .
