These L series batteries are an industry standard. Smaller form factor of these 550 batteries allows use in areas where you need more run time but less bulk. They strike a nice balance in that regard. I use them to run my cameras, LED lights, monitors, microphones, wireless HDMI and SDI transmitters, all sorts of stuff. Just found a camera cage that uses them to feed an A7RII! Hours of use on a single battery. Great stuff!

Awesome battery for my Video Walkman! Works extremely well and would defineitly recommend it to anyone using this type of Sony battery! Also, being from Sony, it's the only recommended batteries for use of Sony equipment, so don't use any other type, whether in different type. Great!! Wouldn't have been happier!!

I have no idea how long this will last of course, but it has this far kept a charge very well.

This is a perfect replacement for original Sony batteries that no longer can be charged because they are 20+ years old. I still don't know how long they will last on a charge - I haven't been able to run them down yet! And the price is sensational, especially since they come with a wall charger. Fantastic deal for those of us who still love our analog camcorders.

I was able to fully charge the battery and it works with my equipment. Have had it for less than a week. I’m happy to say, So far it is working good!
