Wasabi PowerBattery (2-Pack) and Dual USB Charger for Panasonic DMW-BLF19 and Panasonic Lumix DMC-GH3, DMC-GH4, DC-GH5, DC-GH5S, DC-G9

It works, very reasonably priced.

My personal experience with these batteries has been great. The charger is a bit lacking, and the batteries don't seat very well in the charger but it works.I just had my first battery die and I bought these Aug. Of 2022. Testing with a multimeter indicated the second one is on its way out. Overall, I would recommend them highly. I don't usually like giving something 5 stars for doing what it says it will; but these days, a 5 star indicates it's MOST LIKELY not going to just blow up in your face. Good job not blowing up my face or house :)

Great batteries, brings me up to 3 total including my single OEM battery.Havent been daring enough to throw my OEM on their dual charger... but maybe I should.I have used these for all-day hybrid work on my G9, each battery seems to last about half the day depending on how demanding I am. They have been reliable. I have used them in subfreezing temps for astrophotography a few times for time-lapse or the "green" 2023 comet.Compared to OEM, I can't tell a battery life difference. Keep in mind I came into my G9 and OEM battery used... I can't compare to a new OEM battery.I however compare price - 2 OEMs (no dual charger) would cost 4x what this does. If the OEMs are better, it is marginally, not "4x". It really is a no-brainer.

I have a bunch of BLF-19 batteries. After using them sporadically for a year I knew that some were "bad" but wanted some way to test and measure them. I bought a load tester from Amazon, a charging adapter plate, wired it all together, and spent the past few months running each battery through a series of charge and discharge cycles. I used the Wasabi USB charger(s) that came with the batteries. The photo shows the results.Green cells mean the charger light turned green at charge completion. Sometimes, the charge light just goes off. I dunno. It seems to be battery related somehow.Note that 25% of my Wasabi batteries would be would I consider "bad" or "failed" (red column headers).I guess the lesson for me is: 3rd party batteries are probably fine, not as good as OEM, buy extras, and test them to weed out the bad ones. Or spend 6x on original Panasonic batteries.

I’ve been using wasabi batteries for years. Got my first bad one when ordering these for my g9. Replace battery no questions asked. I’ll continue to use them for my OEM battery needs. Great company.

I purchased my Panasonic GH5 + 2 x Wasabi Power batteries + 2 x Powerextra batteries in April 2018. Today Oct 2023, I'm surprised that only the 2 x Wasabi Power batteries withstood the test of time. The other batteries, including OEM, cannot hold a charge. Make sure to drain the batteries completely if you don't plan to use them for a while.

These batteries fit and work perfectly just as the OEM batteries for a much better price. The jury is still out on the longevity of these batteries because I just purchased them, and my original batteries that I currently have and are still using are 5 years old.

Las baterías cumplen con lo que prometen, pero el cable del cargador es de muy mala calidad. Tuve que reemplazarlo casi desde que lo usé por primera vez.
