Rating: - Fine battery!
Battery came charged. So I could start figuring out the camera while charging the OEM battery. It does not have a case, but one comes with the camera and it fits fine. Frankly I've carried batteries of this type in my pocket in a sandwich bag. There are some dangerous batteries out there. Does anyone think that Amazon would sell them? I don't think so.
Rating: - Great battery
Battery works as advertised. I can run a good long time between charges. No complaints here!
Rating: - Battery failed after one charge
Upon receiving the battery I charged it as instructed and put it into my Panasonic DMC-TZ5 camera. The battery slid into the camera with no problem. When the battery needed to be recharged I attempted to remove it from the camera. It was stuck and would not "pop-up." I finally got it out and discovered it had expanded and would now not fit back into the camera. I returned it to Amazon, but have not yet received a credit. I purchased a second Panasonic "original" battery at twice the cost, but it works. I would not recommend any battery for the TZ5 other than the original Panasonic battery.
Rating: - Do not order
Do not order this item! It does not come with a plastic case as one reader says it did. With all the issues with Lithium Ion Batteries, it is extremely important that spare batteries be stored in a plastic case. Item is not UL approved either.
Rating: - Short life
This is a fine backup battery, but has a significantly shorter life than the Panasonic.
