i could of sworn i answered this post maybe not....This charger sucks....It will take you forever to charge you batteries, also order two..They are not tightly made...My first one for my diamond broke in a week the other one i still have i just charge the battery over night "a long night".Other than that "yes it does work" and its only $5 and will take a week to receive. Order it maybe quality has changed.
Oh the OEM batteries can be found from alot of vendors. Google
