However, the maximum record time varies depending upon how you are using the camera. I have both an FDR-AX100 and an FDR-AX700. The battery life is quite similar for both camcorders, and both camcorders use the same batteries. If the camcorder is up on a tripod with the lens up high above people's heads, looking out at a wedding reception or other event, where the camera isn't refocusing, isn't zooming, and is just plain recording in UHD definition and with sufficiently large memory cards, it can record for just under four and a half hours. Not refocusing and not zooming save a LOT of battery power. As always, your mileage may vary. However, when roaming around a venue, recording a few seconds to a few minutes at a time, focusing and refocusing, and zooming in and out a good bit, the "record" time can be considerably less than four hours. I think the worst I've seen was just under three hours, but that was under nightmare conditions. The battery will charge "on camera", like the standard battery, but it takes significantly longer to charge, so be sure to allow adequate charging time. I have two of these Sony NP-FV100A batteries. One is now over six years old, and still works well, but then it has primarily been used on a Sony FDR-AX100 for recording plays and other events that run two to three and a half hours, with only occasional start-stop-start-stop recording. I think the last time I purchased a Sony NP-FV100A was last summer when I bought my FDR-AX700, and at the time I think the NP-FV100A cost about $175 to $180. I've been very happy with both of my Sony NP-FV100A batteries, and I've used them in both my Sony FDR AX-100 and Sony FDR AX-700, with similar record times in either camcorder. The Sony NP-FV100A is a bit pricy, but well worth it. Just be sure to get the "Sony" brand battery, and a "new" battery. There are some off-brand batteries that claim to be equivalent to the NP-FV100A, but as an acquaintance found out, the Sony camcorders are sometimes unhappy with the non-Sony batteries, and either report the battery as drained, or refuse to charge them, or they run out of juice prematurely. And then there are "used" batteries out there as well. In a pinch while out-of-town I purchased a "used" battery and while it appeared to take a charge, it was exhausted after about 40 minutes. I'm not sure if it was used until it was worn out, or abused, or what, but if you are recording something important, be sure to buy a GOOD, RELIABLE battery. Just a thought - If you need even longer record time, get yourself a professional sine wave inverter, and put it, its mattery pack, and the AC adapter for the FDR AX-700 in a backpack, with the FDR AX-700 connected to the sine wave inverter just as if it were plugged into a wall jack. With that configuration you should be able to record seven or eight hours, depending on the sizes of your memory cards. Since I'm always asked if there is anything on the AX100 that isn't on the AX700 that I miss, I'll add... "yes, I miss the button on the AX100 that puts the microphones in a 'sound from behind the camera cancelling mode' that I really miss." There are times when direction is needed and I don't want to have my "camera operator" voice, or a dance instructor's voice booming on the recording and overpowering the sound from several feet (or yards) in front of the camera, and at those times I use my AX100, as the AX700 lacks that important feature.
