Well, that's where you're wrong! Throwing any lame batteries shows them that you're angry. Throwing rechargeable batteries shows that you've taken your rage to a whole new level! You're sending a message to that opposing players; you're saying, "I could've recharged these things 100s of times and kept using them over and over, but instead, I chose to forgo practicality and employ them only once, for the purpose of pelting you. Such is my hatred for your team!"
