    Purchased "Energizer - MAX Batteries 9V (2-Pack)" for use in a home smoke alarm detector. The two batteries should have lasted at least a year. The first battery lasted 30 days, and the second battery lasted 28 days.

    This is a good battery for smoke detectors. Although it would be better if the shelf life lasted for at least 10 years like the other brands.
