Kastar Replacement Battery NP-FV50 for Sony NP-FV30 FV50 NP-FV40 NP-FV70 NP-FV100 and Sony Handycam HDR-CX580V 760V HDR-PJ540 650V HDR-PV790V HDR-TD30V FDR-AX100 DCR-SR DCR-SX HDR-CX Camcorders

I am certainly not disappointed in my battery that I ordered. It charged and worked very well in my video recorder. I am very pleased. I needed a spare battery to use. It is hard to make it on one battery when you are recording events special in my life. I cannot express how happy I am with this purchase. No cons so far, it is still working very well.

Thought for $11.99, couldn't go wrong. Slapped it on my Z90, charged it up. Only says 98%, but my Watson battery is the same. Hit record and waited...at 30 minutes recorded it was at 48% indicated. Came back a bit later and it was dead but had recorded 45 minutes on the SD card. Charged it up for 5 minutes to see where the % would be near "death" and it shows 15%, so fuel meter is pretty usable. Not too shabby for $12, and also more compact than the stock FV70 that came with the camera and is starting to fail. Can't speak to longevity at this time though.

Shorted out after a year. And it over heated causing one of the three pin (XLR) male plug to stick inside the battery. Had it not heard the fan stop noise and had the charger auto stop failed.. I can only guess the outcome. Do not waste your money.

Great product!!

This does NOT work on a sony cam corder. The Voltage, amperage and AH all all different, and when placed into the sony cam corder and turned on, the camera gives error message to use a compatible battery and turns off.

I have purchased several of these batteries and they all seem to work great. Highly recommend

About for 15-year-old camera works like me.

Got it quickly, and it works just like it should, so YAY!!!
