The battery Olympus supplied with my Stylus 820 camera never particularly impressed and has progressively failed in holding it's charge.
This purchase matched the specifications and has so far out-performed the original battery and significantly undercut the price of an Olympus branded replacement by at least 1/3.
My only gripe is a sneaking suspicion the flash isnt as bright, as the results of my picture taking seem slightly darker than expected. However this has been rectified by modifying the camera's settings... I'm getting the results I want, time, after time, after time, after time ... well you get the idea
