Powerextra2 Pack Battery for Olympus BLS-5, BLS-50, PS-BLS5 and Olympus OM-D E-M10, Pen E-PL2, E-PL5, E-PL6, E-PL7, E-PM2, Stylus 1

These batteries are great! They fit my Olympus Pen EP-3 perfectly with no swelling - an issue I've had buying batteries for these older cameras. I brought them on a vacation to Ireland, and I never even fully drained one of them.They hold a charge for a while, they don't swell, and they're extremely cheap. If you need to replace a swollen OEM or third party battery, or just buy some extras, these are a great option. I doubt they'll last as long as OEM in the long run, but for the price, you really can't go wrong.

These were purchased as backup when traveling. They work great, long lasting. Would by again if the camera had lasted as long.

This brand has never failed me when used with dozens and dozens of camera brands (I currently have six different camera models, plus two Blackmagics, and have owned many more in the past, but I have a number of older models that I've kept for various reasons but don't regularly use).Much cheaper than the name-brand, no difference that I can tell. If there is a slight difference in battery life, it's irrelevant considering the price difference.

Good, not great replacement for Olympus OM-D E-M10 mki and mkii. they worked well for about a year and a half and began to slowly lose their ability to retain a full charge. They also began to swell enough that they became a little difficult to get out of the camera. If you just need a battery or two as a secondary to finish your day of vacation pics and video.. these are more than "OK". But if you're a professional who needs the battery to last... buy the name brand replacement. I am not a professional, and don't pretend to be. These batteries work well enough for the hobbyist... but be aware that they do not have the longevity of the OEM factory replacements...

Battery life as good or better than OEM.Fits camera as expected. And the price is excellent.Only time will tell how good they really are. But I see no reason to not believe it will live up to my expectations.

I bought these because my OMD M5m3 positively eats battery life. I am a semipro photographer and use these regularly--at LEAST once a week for 1-2 hours. I have not timed it but these last just as long (give or take) as the original battery. For the price they are a must have. I have not noticed any issues with warmth and have had these for months. The only problem I have had is that they are a little bit loose in the battery compartment. It is a very small problem and has caused an issue 1 time in 2 months. I recently used these for an enormous project and these lasted through several shoots each. They charge just as fast as my original battery too. Additionally, they do last longer with a MF lens.

These appear to work well and charge OK. THey fit the camera. The last third-party brand I got eventually ( a year or two) swelled up so they didn't fit the camera anymore.If the ratings are right, they have more capacity than the original Olympus batteries - but I haven't tried a test to see.So time will tell.

Great for back up
