I need it a replacement battery for my Nitecore p-12 flashlight with more power to run it longer, and this work out great. After placing the order online, it only took 2 to 3 days, then I received the small pkg in the mail and it came with the new battery in the factory seal. Great Experience. Thanks, Ed.
