Are they really 1300 mAh? How long does it power the A7s while shooting video?

I own the A7ii and they work great. I bought 4 of them and they seem to work just the same as the Sony battery. As far as working the same on the A7S I would imagine they do.

Takes AC power thru on camera charging adapter. No prob.11 hr video In a single file?Not sure... i seem to remember reading something in the manual about a limit on a single video file size. You should be able to download the manual from Sony and search.

It's not the best. I wouldn't expect to get more than an hour and a half max off of a full battery charge while actively filming with it.

It is Canon's LP-E6 battery and is rechargeable. For shooting photos, it'll last something along the lines of 300-500 shots depending on how you shoot. I don't shoot video, so I couldn't tell you how long they will hold out for video.

I bought some of these awhile ago. The ones I got were 600 mAh. They work fine and seem to last. I have had no issues with them and have been using them for over a year now. Hope this helps.

The camcorder you are referring to uses a NP-F550 battery (7.4Volt 1800 mah). They are available at this site: http://www.batteryheads.com/camcorder-batteries/camcorder-batteries-sony/sony-ccd-tr917-camcorder-battery-15-5-wh-1800-mah?gclid=CMPH0Inqjr4CFZNlOgodXR8Aag. Amazon has them too.

It was much better than I was expecting. I thought it was very good for something so small and inexpensive. It will video continuously for one hour before you have to recharge it. It is a very fun thing to use because nobody had any idea they were being filmed! Hope this helps!

Yes, that is a rating of how long they last. Each time I buy Power 2000 for my cameras they get better and better mAh.

my girlfriend has the A77 and she says its the same battery, they work just as good as the sony branded ones do and last just as long before they need charging

Amazon's webpage states that these are Li-Ion batteries with 1200 A-h capacity. I know of no reason to dispute these specifications. Please note that the number of images between battery swaps or re-charging depends on the other applications (especially GPS) which may run in background even tho the camera is "off". With GPS in particular, the battery may run down in as little as 30 hours even without taking pictures. Viewing pictures in memory also runs down the battery. The advantage of Amazon's "2 battery special" is that you can charge and carry 2 spare batteries (+ 1 in the camera) for very satisfactory days of full usage.

As far as I know it is same sensor and same AF as in a5100. If you are renting why not A7s. It was build for low light stills and videos.

They should be great for it. They are really good at holding a charge for a long time while being stored and for delivering their power very quickly. The 2 major things a camera requires.

Depends on the quality of video you are shooting. I used it to film an entire football game, but was also starting and stopping a lot, so if pressing the battery use constantly maybe an 1 1/2 to 2 hours on full 1080.

Not the best but good enough. I use in a trail camera and have a smart charger as in that use they only last about 3 days of heavy use, 300 pictures with flash & day & night infred pictures. I have a high traffic count.

King Lear, I purchased two of these and on the label they say 2200 mAh. They're great, lasted forever on a recent hiking trip, took over 400 pictures each before I had to swap them out.

Hey a big Maxe battery and some other options also available that last around 3 to 4 hours, but take a good long time to charge too. Also try the Atomos Recorder which works as a monitor cum external recorder if you have the budgets. Great combination with a 5D Mark III with the full HDMI out.
