It's true, but I'm not sure what 'limited' means in this case. Remember, the lemon isn't really doing much; mostly it's just sitting there passing electrons from one electrode to another (I think the acid may help a little bit, but that's not the most important thing). The metal electrodes are actually undergoing chemical reactions and being consumed by the reactions. So, yeah, the more current you run the more the electrodes will get used up (just like a non-rechargeable battery).
