Hi,

Half dead alkalines work quite well in clocks, remote controls and
other low drain uses.

cheers,
Pete.

If they're small batteries ( i.e. AA or AAA ) then I find that shorting them
with the multimeter leads when the multimeter is turned to current gives a
good indication of their state. From memory, an AA cell will deliver some
1.5A into a short when newish. Of course, make sure your multimeter can take
this current, and only do it momentarily. I used an old AVO meter, the
result you get may vary with the internal resistance of your ammeter when
set to 'current'.
