Alan, lithium-ion AAA batteries require a lower charging rate than other battery types (150 mAh I believe*). Most chargers not dedicated for AAA lithium-ion cells have a charge rate of 250 mAh or higher, and since these are unprotected cells, I felt it was smart to just get the best cells/charger combo available....... and that would be this (IMHO):Will the AW batteries charge on the UltraFire charger I just bought?
I got 2 of them in the mail today. Only opened one and the 2-stage was non-existant with an alkaline at work. The clicky seems to be ON only despite multiple clicks.
I got home and loaded an L92 Energizer primary (I don't have any 10440's) and the 2-stage is flaky. but improving after some deoxit/progold! Function's getting better!
My ohmmeter rates the clicky tailswitch beyond flakey! Fit/finish are OK, and it might a "gift" light if it cleans up it's act further.
I'm almost afraid to open the other one!
