Delivered quickly in perfect condition with tracking. Works perfectly in the PEN E-PL2.I had a PEN-E-PL1 with two batteries and was told by the camera shop when I bought the E-PL2 that the E-PL1 batteries would work in the E-PL2 but they won't. The E-PL2 battery has four contacts and the E-PL1 battery has three. However the E-PL2 batteries work in the E-PL1 camera and the E-PL1 batteries charge in the E-PL2 charger. Just for your information and not related to the quality of the Wasabi Power battery for the PEN E-PL2.The Wasabi Power battery for the PEN E-PL2 looks like it is very well constructed, identical to the original battery and comes with a cover for the contacts unlike the original battery. Charges fine in the charger and works fine in the camera. I highly recommend it.

I've given it a five-star rating for now, because it seems to charge fully and maintain its charge well. Of course, this is no indicator of how it will hold up over the long term, with many charge/discharge cycles, but it was inexpensive enough to risk, and I'm looking forward to seeing how it holds up.This brand of battery is also one of few that has the extra contact, which as far as I know is for overcharge protection circuitry. Of course, this will also help the life of the battery.

This battery works fine in a PEN E-PL2 camera and does charge with the stock Olympus charger. While it is advertised to have a much larger capacity than the standard Olympus battery it replaces, my experience using this battery was that there wasn't much of a difference. Perhaps the biggest difference between this battery and the standard Olympus battery is the price, and it is here that this battery shines. It is certainly worth the price.

When you need a battery, you need one. The price was a good deal.

Works fine in my camera. Charged as I would expect and fit properly. I may update this as I get more usage experience. At this time I expect to order others from this brand.

The camera uses a lot of battery power, so I got two extra and cycle them as they are used. These perform as well as or better than the one that came with the camera.

The good news: Inexpensive battery did great for the first year. Five star review.The bad news: After about 13 months of use the battery started to swell & bloat. It swelled to a point that I had to pry the battery out of the camera since it was stuck. I guess I could jam it in the camera, but would be a very tight fit, and likely would have to pry it out again. That said, I'm not going to use it any more.Use of the battery averaged one charge a month, with one or two weeks during the year that would get multiple charges. I was also using an OEM Olympus battery along side this Wasabi Power Battery. Both batteries incurred the same usage and charge patterns. The OEM Olympus battery is actually slightly older, has a little more use under it's belt, but shows no sign of swelling, bloating, or any other abnormal deterioration.Attached picture shows swelling. Battery swelled in the center, so you can see how holding it down on one end makes the other end pop up.

This is a reliable battery that lasts as long, if not longer, than the manufacturer original. The Wasabi brand changed my mind about third-party batteries, which in my prior experience have been inferior to the OEMs. I will look to this brand for batteries in the future.January 2016 Update:I haven't experienced any swelling issues with the battery — I'm using only my original Olympus factory charger to charge it so maybe that's why I haven't encountered that particular issue — but I have begun to note that when the battery charge reads half, it just up and dies without warning. The camera cannot be powered on after this happens even though the last-known charge has in every case registered as half full. As soon as the battery drops to half it is best to remove it right away because failure to do so means that any powered lenses will be stuck before they have time to retract, and the battery can also die in the midst of writing the file to the SD card, too, which could potentially corrupt the image (if not the entire chip).With my original E-PL5 Olympus battery, I can take quite a few pictures at the half-charge point and the camera will always allow me to see the icon change from green to red to warn me that it's time to power off. This battery, on the other hand, will continue to read "green" (at half charge) only to die with no further transitions. At this point the battery still takes a charge and I can capture a lot of pictures before I reach the half-way point on the charge but because I can't use it after it reaches the half way point I'm losing about a 1/3 of the useful capacity as opposed to the factory battery that shipped with my camera. Because of this issue I'm taking two stars off my original 5-star review.
