I'd check the contacts for the battery, and hotshoe. make sure they're
clean. also, assuming the A-1 is somewhat similar to the AE-1... does the
meter function properly (only when shutter release is half-way down)? if
it's alwats metering, that'll lower the battery a bit faster.
sorry, I know nothing about the A-1, just cameras and electronics in
general.
