AA batteries what is a full charge

Recently had a few probs with AA batteries for digi cam, the batteries are
probably 3 years old but have no idea on how often they have been recharged.
Recently after charging they dont last long (have ordered a couple of new
sets) Anyhow I have just recharged them all and on a multimeter thingy they
are showing 14V + or should that be 1.4 V, not too clever with these things
and how to set them.
Would this be a realistic voltage for freshly charged?
Other than when my digicam tells me `change the battery pack` after a few
pics is there any practical way to decide if the batteries are past their
best.
I am assuming the slight possibility of a camera fault, thats about 7 years
old.
That's about the right voltage (1.4V) for MiMH batteries.
Under ideal conditions (Regular use, good charger....), you can get a
few hundred cycles from new, with gradual loss of capacity. Leave them
unused for a while, and they don't last as long.Try cycling them a few
times, and if they don't improve, then they're cheap enough to replace.
I'd only suspect a camera fault if the problem persists with a new set,
or if they go flat in the camera in less than a few days without using it.
