Powerextra2 Pack DMW-BLF19, DMW-BLF19E, DMW-BLF19PP Replacement Batteries and Dual USB Charger for Panasonic Lumix DC-G9, DC-GH5, DMC-GH3, DMC-GH3K, DMC-GH4, DMC-GH4K Digital Camera

These are amazing! Purchased for my GH5 and have not had any issues so far. They work just as well as the OEM Panasonic batteries. I also love the fact that they come with 1) a dual battery charger, rather than a single and 2) you can charge the batteries via USB-C for faster charging. Highly recommended!

Replacing mine after two years of heavy use!

I'm delighted to have stumbled upon the Powerextra 2 Pack deal - a fantastic find for my Lumix GH5's battery needs. The charger is impressively fast, and the batteries have a long lifespan. Overall, I'm extremely satisfied with my purchase.

So like a lot who buy this I do videography and use these types of batteries for my lighting and as you know you might not be able to plug in so you need batteries like these that can last for hours. The problem in the past are the chargers and how long they take. I like that you can now charge two at a time and know how much they are charged. They seem to charge faster. I would recommend this if you are looking for these types of battery.

Charged my batteries quick and batteries held their life pretty dang well! Such a lifesaver

This is a great replacement battery and charger for my Lumix G9. I really like the charger and the fact that it has both micro and USB C.

Honestly, I've only had these for a short time. But a weekend shoot tells me compatibility is good, longevity appears to be good and fit and finish are good. I'd buy again.

Not as good as OEM battery life. Dies %50 faster.
