Genaray 4 x NP-F770 4400mAh Batteries & 4 x Compact Chargers Kit

I'm very impressed with these Genaray batteries. I have a few OEM Sony NP-F batteries and these Genarays compared to them very favorably, I haven't noticed a difference. Build quality is just as good as OEM's and their run time seems the same to me. I love that this kit comes with 2 chargers. You can never have too many chargers. And I prefer that the chargers have built-in plugs' that fold away, as opposed to a cable that can get lost or broken. The chargers have an easily identified led light that is red when charging and green when fully charged. So far, I've used these batteries with lights, monitors and even an older Sony camcorder and have had zero issues. They work great.

I use it with my ninja v and it works great don't know exactly how long they charge it but at least 2 hours I think.

These batteries work very well. And I love that this set comes with multiple compact chargers (2). Trust me, it's nice having multiple chargers. I like that the plugs fold away when not in use. This helps when storing them, as it makes the form factor smaller and also helps prevent them from breaking or bending. Having the plugs built in eliminates the need for an extra cord too. Having clear, easy to identify LED's is nice as well. Red means it's charging, green means they are charged. Very simple and easy to identify. As far as battery life, they are working good for me. I have Sony OEM batteries and these Genaray's seem to work just as good in my opinion. I haven't done elaborate tests, but I see no difference in quality or run time. I am also a fan of the NP-F770 size. I think it is a nice, happy medium between the 550 (not enough power) and the 970 (sometimes too bulky). These work great for all kinds of things, and are perfect for external monitors, wireless transmitters, camera lights or anything else that you want a good amount of power, but would like to keep down the size and/or weight. And the price of this bundle is great too.
