Haha... that's funny. I've just seen those litithium ion batteries or some new type of battery come out. I forget what it's called but it's really expensive and I heard it lasts really long...
So don't make B battries because um could you imagine this
Customer: Can I have some B Battires
Employee: (show customer rack full of battires)
Customer: Wheres the B battries
Employee: (points at rack)
Customer: NO B BATTRIES!
Employee: (points)
Customer: (writes B-Battires not battires on employee forhead showin ghim in minor)
Employee: (Confused since the words are backwards)
Customer: (slaps employee and gets arrested for assault)
