You guys that cannot tell the insulator apart from the others, Put your volt-ohm meters on them @Mooch,
His testing showed a huge difference in the resistance values between the authentic and fake.
From the text of the test above.
"The internal resistance of the good batteries ranged from 22mOhm-24mOhm (0.022-0.024 ohms). The bad batteries had internal resistances of 39mOhm-41mOhm, a significant increase. This high internal resistance causes huge voltage sag which leads to very early weak/low battery messages from the mod. This is one of the best ways to determine if you have one of these bad batteries."
