NP-F330/NP-F550 Battery Backups
on October 27, 2013
I rated this item as satisfactory and acceptabtle. The batteries arrived ahead anticipated time for delivery. I needed the batteries for an upcoming trip to add to the single battery with the camera. I oririginally wanted the Sony Mavica NP-F330 batteries. The item description mentionened the version F330 and F550. There was no way to identify the separation of the two versions. The products arrived and I noticed the markings on the batteries indicated "NP-F550" instead of being marked as "NP-F330". There was no documentation with the batteries that would explain the interchangeability of the two versions without harming my camera. Forunately for a little luck and blind trust/faith, the batteries worked successfully. Customers will benefit and understand the product better IF there is a method to separately order items individually according to sizes, colors, or versions of an item. Also helps if there is some type of documentation explains the interchangeability or multi-function use that will not harm the consumer's property. Otherwise, I would have considered the highest rating. The backup batteries function very well like the original primary battery. The batteries have extented the use of my camera. I am not restricted to one battery which in the past resuled in my missing the moments for more pictures. I am overjoyed that now I have the ability to take more photos without a worry about the power in the camera. The batteries have not harmed my camera and continues to work very well.
