Wasabi Power Battery (2-Pack) and USB-C Dual Charger for Olympus BLX-1 and Olympus OM System OM-1/ OM-1 Mark ii

They are a direct replacement battery at a fraction of the cost of the manufacturers branded batteries. They work flawlessly and hold a charge as well as the OEM batteries and last as long, if not longer. Recommended.

I recently bought an OM System OM-1 mkii, and thought it good to have some spare batteries on hand. I like that this comes with a USB-C charger (makes it easy to use on the go), and I no longer have to recharge a battery with the camera. The camera recognizes the batteries and their health. Far cry from my Canon 5D4 (where not all 3rd party batteries are recognized).

it appeared to work initially, but after using it for 10 weeks I put it fully charged into my camera, intending to use it for a shoot the next day. When I tried to turn it on the next day ,it was dead. I like the charger that came with the 2 batteries, have never gotten comfortable with charging batteries in the camera. But for this battery to crap out after only 10 weeks of use is very disappointingEdit..... it turns out that the camera, which had taken a dunk into a river, appeared ok, but was damaged electronically. My issue was with the camera, not the battery. I plan to order 2 more.

This is a fairly typical battery charger and set of batteries. The charger is the usual lightweight plastic with two indicator lights for either charging (red) or fully charged (green). With no rubber on the bottom it can slide about. The two included batteries and the the OM battery both fit well - snugly - and charge without a hitch. Speed of charging is the customary, which is not especially fast. The batteries work fine and fit perfectly in my OM-1 Mark II and I have no complaints. I've used Wasabi batteries for years, as well as many other aftermarket brands, and I've been satisfied with their products. While this kit offers nothing outstanding to set it above its competitors, I went with Wasabi based on my past experience and I've not been disappointed. If I remember correctly, this kit cost a bit more than some others on Amazon, but I was willing to pay it for a known brand and I'm happy with it.

The build is satisfactory. Functionality of the batteries seem the same as OEM batteries. I do not have an OEM Charger to compare the functionality. The charger is smaller and lighter than the OEM charger. The batteries display on my OM-1 Mk II Screen and EVF the same as the OEM batteries. Since I have not used them for an adequate time, I can't rate their charging speed and battery life compared to OEM batteries. After I have used them for several discharge/recharge cycles and a consistent time using in the actual cameras I will update my review with the results.

Battery swells and jams in camera. Maybe a fluke. I’ve used others in same line with no issues. Budget offering so….

I've used Wasabi batteries and charger before with my Canon R6 and now for the new OM-1 MK2. The charger works fine with oem batteries and the wasabi batteries work fine in the OM-1 with no issues. Life is quite good, although not a good as oem. But I can walk around with 3 batteries that work well and save about $200 bucks or more so - do the math!

I've used Wasabi batteries in 4 or 5 different mirrorless cameras and they have always been fine. These BLX-1s are the same so far. Any difference in capacity or longevity from original equipment isn't noticeable to me, and is dwarfed by the cost difference. The two-bay charger is handy.
