Wasabi Power Battery (2-Pack) and Dual USB Charger for Olympus BLN-1, BCN-1 and Olympus OM-D E-M1, E-M5, Pen E-P5

One of the batteries works great. The other refuses to hold a charge and lasts me less than 10 minutes....Wish both came in good condition.Edit: First time using Amazon's messaging to contact the seller. Seller was very quick to respond and sent out a replacement battery. The working one from the first order has been working great so far, no complaints there. Updating the star rating for the quick and excellent customer support!

Great Batteries that hold their charge well. Can't ask for better for the price. Charger is very nice, and works as expected.

Solid replacement batteries and charger for my camera. Holds a charge well and having the detachable cord on the base makes it nice for storage.

These are working okay on my old Olympia and I would purchase agian.

Third party batteries can be very hit or miss. Wasabi seems to be one of the brands you can trust. They hold good charge, seem to have swelling issues much less often than competitors, and are much more cost effective than OEM. With ALL batteries, even the OEM ones, some rules should be followed. Always prefer the charging dock to in-camera charging. Do not store batteries at 100% (30-50% is best for lithium ion). Don't leave them in a hot car, and don't use them if they took a large drop. Follow simple rules, and quality third party are just as good as the originals.

The fit of these batteries, even the geunine Olympus, is tight in the Pen-F. Of the two I bought, one swelled just enough so that I had to use extra strength gaffer's tape to put it out.

Purchased these for use in my Olympus EP-5 camera - they work fine as does the included charger. I have Wasabi batteries now for three of my different brand cameras (Olympus, Panasonic Lumix and Sony) - they all function well and seem to be as efficient as the original manufacturer branded batteries I also own.

I have originally owned these batteries in 2019 and after several years of use, the battery life finally reached its end. For an off-brand battery, I'd say that lasted for quite a long time. Thinking I'll have the same experience again, I decided to purchase two sets of battery packs this time. Boy have the times changed.Upon arriving, the batteries fit in the camera and works just fine. So I packed it for our trip and placed it inside my camera bag next to my older Wasabi batteries as well as my original Olympus battery (which is still rocking on by the way). After arriving at our destination, I opened my camera bag and found all four batteries have ballooned and expanded to a point that it no longer fits inside the camera. It was highly concerning especially after hearing about exploding batteries in airplanes. It could've happened to us.The camera bag went through x-ray and brought on the airplane, which is as routine as it gets. The other batteries have no issues and are placed directly next to these batteries in the same bag. Only these four batteries reacted this way.I have contacted Wasabi for an explanation and resolution. Unfortunately I was not able to ship this back to them because that would require either flying back with it or figuring out how to ship it back to them from our international location. I want to avoid a potential fire hazard.I cannot recommend buying these batteries at all seeing that this is how it reacted to traveling.
