Title: NOT A Replacement For A Sony NP-F330 or NP-F550
Review: The technical specifications listed for this Polaroid battery show it as 3.6 volts. If 3.6 volts is correct, then this Polaroid battery is NOT a replacement or substitute for the Sony NP-F330, NP-F530, or the NP-F550 batteries. The Sony batteries are 7.2 volts.One star because it will not work as a replacement for the Sony batteries.
