I too ordered one of these batteries from BargainCell because they stated it was in stock, and it was the cheapest option. I waited several weeks and it didn't arrive. Finally, I received an email from them saying they were cancelling my order because they didn't have any in stock. Because they cancelled my order I cannot leave a 1-star rating for BargainCell! I checked Amazon and BargainCell still listed the item as being in stock, and the listing remains the same today.If you actually want your battery to arrive, buy it from Accessory Genie.The battery I received did not fit properly in my FZ20. It went in okay, but to get it out I had to pry it out with a knife after several minutes of tapping and wiggling the battery. The problem is that the plastic on the sides was formed incorrectly and has bulges. I carefully took a utility knife and scraped off the very top layer of plastic on the sides and now the battery fits and works just fine.
