battery question-how come I can't do this?

[skeeter@ccia.com]

My digital camers would use up more batteries than there are skeeters in a nudist camp....so Energizer lithium was the solution to that...I have used the same batteries all summer long...and that includes the kids/wife using it too....now the question..can I get lithium batteries in the 6v for the game camera? I have yet to find them.
