touched a gray one, it flashed white, made a weird noise. didnt feel much afterwards... until i tried using my laser drill. thing was out of power, when i was sure it wasnt a moment ago. checked the rest of the batteries i saved up, same story. weird. avoid. might be worth throwing myself at one of the zappy ones to recharge them...
