The battery arrived within 3 days of order and fit just fine. There is no label on this battery except for voltage (3.6V) and amperage (900 mAh), which is greater than the original Panasonic battery (830 mAh). I don't think the difference will harm the phone at all, but it is a difference to note. Since there is no model number on the replacement battery, when the time comes to replace it a few years from now, I will have to somehow remember or figure out what the model number is. Otherwise, it works just fine, and I consider it a good purchase.
