Doing some math, looks like a CR2032 is roughly 200mah while AA is 2000mah. So if CR2032 lasts one year, then the AA will be 10 years, two AA would be 20 years. I guess in that case lithium would be the way to go. I just know for your typical wall clock that takes a single AA, whether it is lithium or alkaline, both won't make it much further than a year. |
