'genuine' nokia battery with no hologram - definitely a fake?
 

just bought a battery from this auction last week:

genuine my eye.... doesnt even have a hologram. here are pics left to right:
new battery (31.97g), from E71(31.17g), from fall2012 buy.com N810(30.12g), from E6 (31.22g maybe swapped with an older E71/E72 batt.)

oddly enough the n810 looks the fakest of them all, but note the new battery has no hologram (ive NEVER seen one without), and is slightly different. however it also is dated newer than all the other ones.

new battery is substantially heavier than the two im pretty sure are real. N810 is substantially lighter than the two i think are real
