Hmm, I don't know if the thermometer is worth it to you, but you could take it to a jeweler shop and test the battery.
But if that doesn't work, I would just buy a new one, they aren't very expensive after all. But hey, since you had problems with digitals, why not skip the crap and go straight for a temp gun. You can get them for about $20 bucks at most hardware stores.
