I burn up AAA Batts with Bose noise canceling headphones, so got this. Very confusing instructions (Green light indicates charging... NEVER goes out?? If charging 2 batts, put them on either the left or right... OF WHAT?? The charge thing I read how long on chart....11-16 for first charge... THEN WHAT?? I guess it just likes 16 hours always. 2 batts at a time must mean 2 left of center, or right of center. Eveready makes good stuff, but get someone who speaks English to write the dang instructions.!!!
