What does mean AA or AAA on batteries? I know difference between those but i was just wondering what is difference in their's titles (what does aa or aaa stands for). |

Typically, the larger the battery the longer it will maintain a given voltage. AA, AAA, C and D cells are 1.5 volts. Since the D cell is markedly larger, it will maintain 1.5 volts for a much longer sustained period than the smaller AAA cell. Thus its widely preferred for D cells in say, flashlights, where you want reliability, and why that digital camera seems to go through AA batteries like water. Consumer tests have shown that most brands of alkaline batteries are nearly identical in battery life. The difference is when you start getting into things like expensive lithium or rechargables like nickel-hydride. |

I think it has something to do with how many cells the battery has inside of it. But other than that, all I know is is identifies the size of the battery. |
