3900mAh VW-VBT380 VBT380 VW-VBT190 VBT190 Battery for Panasonic HC-V800K, HC-VX1K, HC-WXF1K, HCV520, HC-V550, HCV710, HCV720, HC-V750, HC-V770, HC-VX870, HC-VX981, HC-W580, HC-W850, HCWXF99

Works and fits well. More than double the recording length/time than the factory battery.

This worked just fine with my HC-VX981 Panasonic camcorder. Battery indicator works and indicates a little over three hours battery on a full charge. Don't expect to use all that though. I think it's good for maybe 2.5 hours, then after that your on borrowed time. That's just the way things work, it's not the fault of the battery. For the price, I think it is a good deal.

I wish I had bought this a long time ago. I video my son’s soccer games. The standard battery that comes with the camera holds about two hours of charge minus use of the zoom. This one holds 4 1/2 hours easy. It’s twice as “long” so it sticks further out from the back of the camera but that isn’t really a problem at all. I highly recommend it if you need more power or just don’t like having to constantly charge the standard Panasonic battery.

Battery lasts for hours, double the time that the one the camera comes with which is crazy! Works great!

Just what I needed.

These batteries are a little better than originals. Last about 15% longer in recording mode.

Fit my camcorder and holds a good charge. I can't attest to durability but will report in a few months.

Camcorders are notorious for power consumption. I lost my extra battery so I bought this one. It has a great run time on my Panasonic HV-C 720 camcorder.
