Review: Its a replacement battery. - Purchased this as a battery swap for a Nokia 3260 flipphone. It fit beautifully and now my phone can last much longer in between charges. I like having the original factory battery as a backup (It was 1450mah) and using this one as the main battery. Fit as expected and was easy to install.
