Wasabi Power Battery for Olympus BLN-1, BCN-1

Battery drains a bit faster than the original Olympus batteries in my Pen F. However, for the price, you can buy 3 of these for the price of one OEM battery on eBay.

Worked great in my Olympus OMD me5. Now we shall see if has longevity as does the original Olympus battery.

First they work great and the capacity is better than the original batteries.All (2) of my batteries started swelling after 2 years and now no longer fit my camera (too thick).

Wasabi batteries have been used by this reviewer for several years in various Olympus and Panasonic cameras. The following information is a result of observation, not controlled testing:1. Out of about a dozen batteries a defective one has never been encountered.2. The run time of these batteries seems to be the same as the OEM batteries.3. The may self-discharge more quickly than the originals. This is over a period of weeks, not days or hours.4. They seem to require a couple charge-discharge cycles to come up to full capacity.5. Total life span seems similar to OEM batteries. This life span is in years, not cycles, as none of the batteries under review here has been used hard enough to die from cycling.6. They are inexpensive and easily replaced. There seems to be no reason not to use them and keep a spare in your pocket or gear-bag at all times.7. The new, small, USB-powered, chargers are very functional and easy to stow. Try one of those also.

This is an excellent backup battery to have in your camara bag.

I bought this about 1.5 years ago and the battery is starting to warp. It's still usable but, very difficult to get out. It's 1/4th the price of a Olympus brand battery so I am not too upset at it's longevity however, I won't be buying it again.

Have had a few Wasabi batteries for various cameras. They don't seem to last as long as OEM - find that they expand after a few years (so don't store the camera with a Wasabi battery installed). But, for the price, they great to have on hand for long days or as back-ups.

batterise worked flawlessly.....plenty of power more than enough pics. per charge work and charge fine with OEM charger use withO EM5 mk ii. (the shots per battery depend on how u use of your mirrorless camera ... u can't compare it to your DSLR....2 different camera platforms)
