BA-2B-LI42B

worked on my old Samsung S3 phone.

No problems here.....good purchase, quick delivery

Batteries charged fully fairly quickly, and performs as good or better than the original. Too soon to vouch for longevity, thus the 4 stars

I think the mAh rating of these batteries is overstated. However, that is just an observation of performance, not a conclusion from actual tested data. These batteries only slightly out perform the original factory supplied Olympus battery that is over two years old. For the price tho... who can complain? Not me.

Took a chance and ordered a pair for just < US$10. The battery rating claims to be almost twice the amount of power of the original Olympus battery. Both are LI-40B/42B/EN-EL10 suitable batteries. They arrived with a partial charge; I charged one in the recorder with a USB cable: RESULT! The original battery I could find was now dead, and would not take a charge. They were not such great batteries to start, giving maybe up to 3 or 4 hours of use on lower recording settings and playing back a few recordings. Well, if the battery at least matches the originals' performance it'll be a good deal, and I'll be able to grab some random sounds with more control than my *Phone 11 Pro Max, in stereo, PCM mode, with digital out...also has a video making feature with HDMI out, mic, earphone and SD slot (no BT though): there's a lot of features on this thing just crying out for a good battery power source. Hopefully these will last....

Great value

They worked for what I needed, arrived on time

Received 2 batteries and neither will take a charge Just junk For the price I figured if 1 worked I was even but if both worked I was ahead of the game. Nope , both junk. My own fault for expecting to even get one of the two that would actually work. You get what you pay for. In this case I got nothing for about $8 including shipping. Live and learn. Update They don't work because they are shorter in length than the olympus OEM battery. They may work in other cameras but if its an olypus they are short by several thousands of an inch. Just enough so the contacts on the battery and the camera do not touch. If you push down on the battery with your finger they start charging. Of course I can't have my finger there every second its charging or when taking pictures. Maybe the manufacturer will read this and take some corrective action.

Received batteries quickly, seem to be decent quality for a inexpensive battery. If they last longer than the Olympus it will be well worth it.

Great Thank You

Good. I can only rate it once I see how long it lasts.

exactly what I wanted and needed

ok item
