Kastar Replacement Battery for Sony NP-F960 NP-F970 NP-F975 and Sony Camcorders

Fast delivery and the items were better than described. Got two of these for the CN-160 LED Light. Out of the box, both batteries had a 50% charge. That's about right for a new battery. Since I have a dual charger, I can tell you both batteries charged evenly and hit 100% at the same time. I haven't completed the first cycle, but, the batteries DO work. I'm feeling good about having these.Others have reported getting, "...30-45 minutes with the LED light at full power..." out of a 2000 mAh battery. If that's true, I should get a little over 2 hours and 45 minutes from each of these batteries (at full power). ...Sorry people! I don't need my LED light to work that hard and I'm not gonna do that kind of test for this review. I do "Event Videos". So, if I can get 4-5 hours of "fill lighting" (maybe, 1/4 to 1/2 power), that's about two events on one of these. ...of course the second battery would be the emergency backup....Back to the Seller. The batteries were very well packaged. I can't tell you about their Customer Service because I didn't need to contact them. ...and that's a good thing! The purchasing process was completed without a problem. ...again, that's a good thing!!!========= Follow Up Information ==========Damn it!!! Curiosity got the best of me! I ran the light at Full Power for the first cycle of this battery. I'm happy to share, the battery powered the light for about 3 and a half hours!!! Of course, for the last 30-45 minutes, the light was getting dimmer and dimmer, but, it was useable. At the tail end of the battery life, I would just have to get closer to my "subject". ...but, it's not like the LED's started emitting "yellowish light". So now, I'm even more "happier-er" having a better idea of the batteries ability. ...Just to protect me, and "other involved parties", YOUR RESULTS MAY VARY.

The battery has been a really great affordable option to power my external monitor and my video light pannel. I shot a feature film using these batteries on the monitor and have shot many music videos as well. I highly recommend them. I have had no problems whatsoever in the 8 months I have been using them. I can shoot all day using 2 batteries on my 7" manhattan LCD monitor.

It is a nice cost effective replacement for the Sony PD170 OEM battery I have. So far so good and without any issue at all. I recommend it.

I had heard good things about these batteries and bought 2 for my Sony HDV 1000U.I've had good luck with a Power 2000 replacement battery for my other Sonys at work, so I thought I would give them a try and avoid the absolutely outrageous price of what Sony is trying to get.Well, I guess I should have know that you get what you pay for.Both of these batteries -- after the first time use -- have begun separating from the base plate. One began peeling away in the camera this morning and the other began peeling away while it was in the wall charger. The weight of these extended batteries seem to be causing the case to separate at the top and start to "sag" outward and downward. The trouble is, that is the way they are mounted on the camera, in a vertical fashion. I was taping an event and just caught a glimpse of some green and white on the back of the camera where all black should have been. I was actually seeing the color of the batteries inside the case as the case pulled apart. I'm going to try some super glue and try to glue the case shut. We'll see what happens there.This does seem out of sorts with the type of reviews this battery normally gets. I have to say the capacity and it's ability to hold the full charge over a week of idleness is outstanding. I've had no problems with the CTA wall chargers I've purchased (and used for 2 years).Hopefully this is an anomaly and no one else will experience it.

This battery works very well with my external HD dsiplay monitor used for my camcorder. Battery discharge lasted for the time expected. Recharge time depends on the charger, but I had no issues iwth this item.

fineIt's an OK battery no complaints !!Finefinefinefine fine fine fine fine fine fine fine fine

Hi!I bought 2 batteries, like in the photo. well, this battery is a copy from the original battery.the Sony Pro Camcorders only acepts InfoLithium. I Know this because the batteries that I Bought here, when I turn on my camcorder it says " Please Install a InfoLithium Batery"so! i spend US$ 88.00 for nothing! I can't use it!Thanks!and if you have a Sony Pro Camcorder, DON'T Buy this battery!

Great quality for the price. (hesitant to say even that because you get way better than what you pay for).I use with a cheaper field monitor (video production) and it works like a charm.
