BM Premium2 Pack of DMW-BLK22 Replacement Batteries for Panasonic Lumix S1R II, S9, G9 II, GH5 II, GH6, GH7, DC-S5, S5 IIX, DMW-BG1, DMW-BGS5 Cameras

I've been using these side by side with the more expensive battery that Panasonic includes with the S5, and I haven't noticed any difference in performance. They have the same capacity, last just as long, charge just as fast, and have worked great. It's hard to believe two of these cost less than half the price of the original batteries from Panasonic.

Honestly not sure if my new battery was bad when I got my gh6 but this battery blew it out of the water. I will buy many more.

The camera indicates that the battery is charging but when plugged in but the battery cannot provide enough power to be able to fully on power on the Panasonic Lumix DC-S5 even with 100% battery.

I first charged both original Panasonic and this BM BLK22 batteries in same charger. Then I put them in my Panasonic camera and started a video recording till the battery dies. Panasonic battery (also Made in China, as this BM one) lasted 186 minutes. But BM lasted 146 minutes. So just %79 of capacity, compared to Panasonic. Sticker on Panasonic states correctly 16Wh 7.2V 2200mAh. Formula is P=V*I. So to be exact; Panasonic rounded their power claim from 15.8 > 16Wh. BM sticker states; 15.8Wh 7.2V 2200mAh. But based on my above %79 capacity test run; BM is more like at 1738 mAh (therefore 12.5Wh).Bottom line: Panasonic costs 4 times what BM battery costs. Although BM is only at %79 capacity; it's still a better value (assuming that it won't fail or warp soon - only time will show).So if you are a professional; you don't want to replace batteries on the job sooner than needed; go with Panasonic.For the rest of us; %20 less capacity compared to 1/4th price is an acceptable value.I wish those compatible battery manufacturers had honestly put correct capacity figures on their product. But I'm not holding my breath on that one.

Bought this a few months ago to use with my Lumix S5. Both batteries work just like the original. No problems so far with battery life or using with camera. Communicates perfectly with camera and default charger. If I experience problems, I will update my review.

Self-discharge is reasonably slow but too rapid for 5 stars.

When you can get 2 batteries for half the price as one 1 Panasonic battery and these hold up just as well. Why not buy the cheaper brand and get 2. I have had no problems with these batteries. I would highly recommend them!

Good have extra batteries for my S5 camera

This is not a battery pack worth buying. Both batteries maxed out at 75% when charged "full".

Good quality batteries for my Panasonic S5 camera. They fit the camera and original charger perfectly. I haven't had the opportunity to check battery life over the originals but I'm not really noticing to much of a difference. They do the job at a fraction of the price. Just hope they last!

These work fine in my Panasonic GH5S camera body, but I can't use the OEM charger to charge them as the bottom side flanges of these batteries are a little different than the OEM ones and they won't slide into the charger.Looks like I'm going to need a 3rd party charger to go along with these....

Company confirmed its not compatible with the GH6. The camera will shut down randomly and without warning on these batteries. The company confirmed that the batteries do not work with the GH6 after a software update. I asked the company for a warranty exchange for ones that do or a refund to no avail (Still within the 1 year warranty window). Luckily amazon stepped in and allowed me to return them for a full refund.

You get what you pay for in this case.
