Are these 3rd party batteries any good?This trick is becoming more common. Panasonic have practiced this for some time. To quote numbers for clarity, the 180/360 batteries, suitable for my three year old HC-V700 camcorder, were available from third parties for around £25 for the larger 360. The 190/380 batteries for my more recent camera the HC-V750 are not produced by third parties yet but Panasonic replacements can be got for £59 (190) and £81 (380) from Amazon.
Seems Sony are on the same game.
In my case Yes. I bought from Digitalmediastore where the VW-VBK 360 (NOT 380) is still 25.99. Unfortunately they only work for the 700 and NOT the 720 - 750 etc. The battery is as good as its description and has a double life compared to the Panasonic 180. (supplied with the camera.)Are these 3rd party batteries any good?
Yes, they're not cheap.I have the Sony FDRAX100 camcorder and was shocked to see that a replacement NPFV50 battery would cost over £70.
No alternative batteries are quite as good as Sony ones in terms of performance, but some are quite acceptable.Is there a good alternative that will have similar performance?
Yes, they're hand-crafted by elves and delivered on the backs of golden unicorns. (Or at least that's the only explanation I can come up with for Sony pricing.)Is there something special (apart from the price)with a Sony battery?
