1)After receiving the package I noticed that neither were in a sealed package.
2)Upon inspecting the copper contact pins, you could see they were scratched (this means they had been installed in a phone. True new batteries will not have the scratch marks on them)
3)I installed the batteries in each phone. Both were completly dead and the phnes would not even power up.
4)I checked the voltage on each. Each showing below 3.2 volts which is bad for LIPO batteries. Running batteries this low will shorten their life and will damage their ability to take a full charge. Fully charged cell phone batteries like these are rated at 3.7 volts. Fully charged you will normally see about 4.17-4.21 volts. Cell phones give you the "low battery warning" signal at about 3.50 volts.
In a nutshell... These batteries are used. My original battery that is now 16 months old, performs better. Ace Harware had some generic Lemar or Lexmar battery for $15.00 that is currently perfroming like a brand new Samsung battery. I would never by from this seller again unless I lost the original battery and needed one to sell the phone. If I could give a "Zero" star rating I would.
