Canon AE-1 Program Battery Life. Based on the original Canon AE-1 Program Manual, the battery should last at least 1 year with normal use. Iām assuming modern-day batteries are better and more efficient than ones from the 1980s when this camera first came in the market, so the 1-year battery life should be accurate.
