My older batteries were not lasting as long as they should. Plus I was using single chargers for each battery.Enter this package. Not only do the new batteries hold their charge, but the older batteries seem to be lasting longer as well. Plus the convenience of charging 4 batteries at once is a game changer.I use the batteries for a feelworld 7 inch external monitor and two of them last me about 6 hours of constant usage now. Prior to that I was getting about 3-4 hours if I was lucky.

These are phenomenally cheaper than Sony's batteries. The camera time counter is not accurate using these, but they work and got me through videotaping a 2-hour performance, using professional Sony cameras, with no problem and lots of battery life to spare.

These batteries last longer than my older NP-F950 batteries. Happy with the purchase, especially for the price -

Good price but inconsistent product. The charger often malfunctions for me and indicates that the battery is not fully charged. Additionally, the contact pin on one of the batteries pulled out after 2 uses. With these malfunctions, if my return period had an expired these would be going back.I was eventually provided replacement products so I've updated my star rating.

These batteries are simply amazing! Now I am able to light my wedding receptions at 100% power for a full 4 hours using my LED lights. No more having to plug in!!
