Olympus BLS-1, BLS-5, BLS-50 Battery (2-Pack) and Dual Charger by Wasabi Power

I had a set of batteries for just over a year and one of them swelled up. They replaced it together with a new charger and extra battery. Service was great.

Came quickly and works great!

Have used Wasabi batteries in multiple cameras for more than a decade. Reliable charge, long life. And customer service was great the one time I had problem.

Making sure it actually replaced the correct battery took some research. That is party because of the revision that Olympus did but if you make a 3rd party battery that replaces two model numbers it's best to list them both on the battery and descriptions and it wasn't.

It took a while to determine if the battery charger had the right usb style... finally found it in a footnote buried on a page on the main site. Charger is a little cumbersome to use as the batteries are a tight fit and don't really click into place so you're never sure it's quite seated. Also there are no good markings to show which direction to put them in, so you're going to have to label things yourself.

Batteries seem to hold charge well and fit the camera perfectly. We'll see how well they hold up over time, but so far it's been good.
