FirstPowerNP-F550 Battery 2-Pack and USB Dual Slot Charger Compatible with Sony NP F570, F550, F530, F970, F960, F770, F750, F330, CCD-SC55, TR516, TR716, TR818, TR910, TR917

The NP-F550 Battery Kit is a great supplement for individuals who use larger External V-Mount Batteries, because of the NP-F550 Batteries’ versatility from being smaller (compared to larger External V-Mount Batteries) but still having the battery-power to power the same devices.For example, I use the NP-F550 Batteries to power the Hollyland Mars 400 wireless kit when I can’t use a larger External V-Mount Battery and the smaller NP-F550 battery does a good job powering the Hollyland Mars 400 wireless kit for a long period of time.Furthermore, the NP-F550 is powerful enough to also serve as “stand-alone” batteries in numerous applications where an External V-Mount Battery may not be ideal for certain users.Nevertheless, buying this particular NP-F550 battery kit with the battery-charger is a great choice if you’re planning to purchase more individual NP-F550 batteries in the near future.NOTE: I haven’t tested the battery-charger to verify if it can properly charge other NP-F battery sizes like the NP-F975, NP-F970, NP-F960, and so on. But, the only difference I can quickly see is the back-end size of batteries, in which all of the NP-F batteries appear to have identical “front plates” where the NP-F batteries attach to devices.NOTE2: I chose the NP-F550 over larger NP-F batteries because of its smaller size allows me to attach the batteries onto the Hollyland Mars 400 wireless devices without the setup being to heavy and also, the smaller size of the NP-F550 allows me to use these particular batteries on an AC’s Follow Focus rig or a Director’s rig without adding any additional (unnecessary) weight to the different rig-setups (while maintaining good battery life and battery power).

It works very well

Perfect for my camera!

These batteries work pretty well with official Sony handycams that use them (only tried it with my CCD-TR940 so far), and the charger also works with Sony NP-FM (InfoLithium M) batteries. My only gripe is that the battery life estimation on my camcorder is inaccurate, but it might get better as I use the batteries more. Average battery life for me seems to be between 2 and 3 hours. I can definitely recommend this battery and charger combo set!

Lights flash red so there's that...EDIT: The seller sent a replacement the next day and offered a refund. No, I turned down the refund because it was unnecessary. New charger works as it should and would recommend this seller because they stand behind their product. Very happy with how this all turned out.

Excellent working condition, help me to keep using old video camera Hi8 and charging time is excellent for me. any problems with conectivity

A LITTLE DIFFERANT FROM THE ORIGINAL, BUT IT STILL WORKS.

I purchased this because I Am an active videographer I thought it would ease the access for fresh batteries to be able to recharge 2 at a time however the batteries would not charge on the double charger as advertised! Luckily the previous single charger I have did so it wasn’t a total loss, because at least the batteries did charge!
