bought this one along with the other, not sure why the seller sent this one when it doesn't state anywhere that it is Li-42B for TG Olympus camera, in any case neither sent works in the camera. Both weigh less than half of the original Olympus battery.
Bought this as a spare battery for a small Fuji camera my wife travels with. How many times has she forgotten to charge the battery and finds out she can't use the camera? Lots! Not any more though -- she packs the extra battery for a backup. Stays charged a long time when not in the camera. This battery is good quality. Shipping was quick.
I was getting this battery as a spare for my Fuji NP-45A. It arrived on time and I'm very pleased with it. It has a slightly higher rating (900mAh) than the battery that came with the camera (720mAh) so I'm happy with the extra capacity. All in all a good purchase. It is holding it's charge well in my camera.
