I think those that advocate changing twice a year are taking into
account some people buy batteries made in China and sold at the dollar
store twelve years after they were manufactured with sub-standard
ingredients.

I further suspect that brand-name batteries bought at a high volume
retailer (Walmart, Home Depot, etc.) have a shelf-life of five years
and in minimal use in a smoke detector of almost that long.




even the best batteries leak,regardless of their "shelf life".
