On a 3 volt circuit, it's usually under around 1.7 volts when you (potentially)start having problems with powered memory.
I'd replace if it measures under 2.9vdc, but I wouldn't consider slightly low a problem yet.
I'm becoming more convinced that modern volatile memory circuits are more sensitive to power source 'cleanliness' than low power.
In other words 2 volts is fine, 2 volts with a 'burp' is not.
'burp' would be like when you rap your flashlight when the light output is low and you get more. Usually the contacts age, not the batteries age.
Edit: You'd be surprised how many times people replace the batteries to fix a problem when all they really had to do was clean the contacts. Sometimes easily done by spinning the battery in place.
(or taking it out and putting it back in)<--which is what replacing a good battery often accomplished.
