Review: Great - Works great in my olympus camers
Review: The most desirable accessory you can have for your digital camera - I have always found that cameras using proprietary batteries, the battery life is gone long before the photo ops re over. With today's high capacity data storage chips, I always run out of juice long before the image chip is full. These replacement batteries for my Olympus Pen are a perfect replacement in terms of form, fit, and function, and they hold a charge for at least a couple of weeks sitting in my camera bag so I have yet to be left high and dry in terms of available battery power. Without doing a controlled study, I would say they perform with about the same reliability and charge life as the OEM battery. I'm a happy customer.

### ⭐⭐⭐⭐⭐ Performs well
*by Y***O on September 10, 2012*

I bought this battery as a spare for my Olympus PEN E-P3. At first I had a bit of trouble getting the original Olympus charger to charge it - it seemed there was some spiel there and I had to snap it in just so in order for it to begin charging. But once I got it right, it charged up fine. Operation is flawless and the battery lasts long. Great price and performance - what is not to like?
