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

No issues with these so far. They don't have as much power as the OEM batteries but we all know that. They still work after a few months and they haven't exploded!

I am very pleased with the Wasabi Power Battery (2-Pack) and USB-C Dual Charger. The batteries work great in my OM1-MarkII. One of the charging ports in the charger was defective but a simple phone call to Wasabi and I had a replacement charger in no time.

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.

Used less than 10 times over the last year since I bought it for travel, one bay recently quit charging. The batteries that came with it still work fine, just have to charge them through the camera, which is pretty inconvenient

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).

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.

I generally like using OEM batteries but Olympus/OM System pricing is ridiculous ($100/OEM battery and $150/charger).The good news: these batteries work just about as well as the originals. The bad news: the charger doesn't properly support temperature sensing. The good news: it charges slowly enough that the batteries never get hot anyway!Read the specs and you will see that it will take over 3 hours at maximum speed to charge a single battery! But luckily, you will have at least three of them, so you can always have at least two charged up. Just mark one of these so you can rotate them properly, and check the temperature of the batteries while they're charging every once in awhile to be extra safe, especially as they age.

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.
