Powerextra2 Pack Replace for Sony NP-F750 Battery for Sony NP-F730, NP-F750, NP-F760, NP-F770 Battery and Sony CCD-TRV215 CCD-TR917 CCD-TR315 HDR-FX1000 HDR-FX7 HVR-V1U HVR-Z7U HVR-Z5U Camcorder

love this brand I can always rely on them. I dont have any big brand (sony) NPF batteries to compare to but these things can run my small led light panels for a long time. I bought a pair three years ago and one finally started having issues (makes the lights flicker). They have withstood a lot of charges and damage. Good quality. Bought another setUpdate - also had a battery fail within a year. So its hit or miss on the quality. Overall bought 6 of these batteries and 2 have failed over the course of 5 years.

After testing, these batteries last 1.75x longer than the batteries that come with GVM products. Excellent quality for the price. If you’re looking for “extra batteries,” these are the way to go.- Professional Videographer

bought 6 months ago just now there was a shoot, worked fine

A good alternative to the OEM batteries. I regularly buy the Powerextra batteries when I need replacements - because they are very reasonably priced and (in my usage) seem to last just as long as the OEM batteries.

I like the size of these because they don’t weigh down the back of my HDMI monitor (unlike larger batteries I’ve tried). Good capacity and duration. No complaints.

This is an update to my previous post ...For some reason one of the batteries came defective, I left the below feedback, and without me having to do anything I received a replacement pair of batteries. Truth be told, this is amazing customer support. I will definitely recommend this product......................................................................................................................................Upon first use of the battery, I got a compatibility error on my camera. One battery worked fine the other just didn't.I bought this pair before and they worked well. I tried to return it but then guess what, I got the "return window closed", message.

At first, I was concerned about battery life as I would use them in my camera monitor for a short period and then turn off the monitor until the next day. When I attempted to turn on the monitor, the batteries were dead. After checking with the manufacturer of the monitor, I found that it continued to draw power even when in the off position. Now I remove the batteries and haven't had any problem with short life since.The larger capacity of these particular batteries adds to the weight of the entire rig (Ronin-S, Full-size DSLR, Lens, and monitor) but the extra life is worth it.

I got this for my Led lights. I have a pair of old yongnuo 300 leds lapms. With this batteries they last for a bit over 2 hours
