question

The battery seems to be good, I replaced the original (deplepted) in my 3D glasses. It works, now I can turn on the glasses and it is operationg, however when I charge it never stops. I don't know if these batteries have on balance and controlling circuit to charge or it is up to the glasses when terminates the charging process. The original batteries was 50mAh but to fit in siz I had to choose this one (40mAh)

Great "tiny" battery

fits my needs for an ultra light battery for a rubber powered R/C airplane... meeting weight requirements... but connection compatiblity, out side the company products... ??
But... the connector is not recognized by the receiver, nor charger... need an adapter... TBD.. they do specify connector type - JST-sh.... charger does not, just assume you know? Receiver specifies Molex1.25 Pico Blade, protected male... yet to find a mate.
