[74.9 Wh] The battery last a long time. I was happy with it. I carried a few extra spares but never had to change it out for the day.

[74.9 Wh] OEM Battery, no surprises here. Wouldn't mind a better carrying case for it, it comes with a simple tiny ziploc bag, which clearly won't last for long in my bag. It would be better if Panasonic shipped this with some type of plastic cover to protect the terminals. But that's a minor detail, the battery itself seems just fine so far.

[0.99 lb] I needed a battery for a long time and didn't know it. When I finally figured out what kind I needed, B&H had the best value and are very user friendly. What a relief. The battery came as I was consistently informed of the status and it helped my camera work again. Basically it was brand new and hadn't been used because it is very complicated. Thank you for all the help!

[74.9 Wh] These batteries last for a long time. It's great to have a back up!

[74.9 Wh] I've had bad luck over the years with off-brand camera batteries. This is the real deal, made by Panasonic, and it's the correct battery for the Panasonic ZS100.

[0.99 lb] When getting spare batteries for electronics, it is always advisable to get OEM.� Some after market ones from other manufacturers are OK, but nothing gives the life like OEM.

[0.99 lb] Well... It is a battery, so it does work and seems to last as long as the OEM battery, that came with my Panasonic Lumix GX85.

[Lithium-Ion] You know what you're getting with this OEM. It was pricey ($40) compared to off-brand batteries (as low as $10?) but I've never had good luck with any cheap-o battery.

[0.99 lb] Compact and longer lasting. Made to order for the Lumix.

[Lithium-Ion] I recently purchased a LUMIX GX7 MFT body to use along with my collection of Olympus MFT bodies and lenses. I have at least 3 batteries for each battery type in my Olympus lineup so I can shoot all day and review my progress in-camera, without skipping a beat. After receiving the LUMIX GX7, I fully charged the battery, and started learning how to use the new interface. Later that day, the battery required re-charging. It seemed to give better service on the second charge. So, I decided it was time to research a second battery. I read a lot of reviews on the LUMIX brand battery, versus several after market batteries. If memory serves, without exception, reviewers were not satisfied with non-LUMIX batteries. Comments ranged from shorter run times and frequent battery failures to the camera not recognizing after-market batteries. Even though the LUMIX branded battery cost more than the after-market battery, I would rather pay for a reliable battery I can depend on, rather than save some money and have the camera out of service because I of battery failure. The replacement LUMIX battery I purcahsed acts just like the one that came with the LUMIX camera, and I am glad I did the research and made the right decision. You should, too!
