As you said a battery is based on chemical reaction, there for the amount of
energy you can get out of it depends on :
Temperature - Low temp. reduce chemical reaction.
Pressure
Humidity
etc.
So, you can get a out of battery warning if you cool the battery and it can
disappear if the battery is warmed up.
There is another effect to consider.
In some kinds of battery there is a "recharge" effect when you take the load of
it. so you can get a `out of battery' message and after letting the battery
rest
for some time the battery warning disappear.
don't kid yourself the warning will pop out again but you'll have a some short
additional time.
In both cases it means that the battery is close to the end of it's life span
and
you should change it.
