A tennis ball may deteriorate for a number of reasons, including usage (i.e., being hit) and the environment (i.e., heat and humidity). Left alone, a tennis ball would, eventually, lose air through osmosis of the rubber core and felt coverings. When struck, the air is forced out little by little. Heat forces air to escape more quickly, and the effects of humidity and being struck wear out the felt covering, as well as causing tiny cracks and holes in the felt and rubber from which air will escape.

Two opposing professional tennis players can go through a brand new tennis ball in under an hour.
It really depends on the use of the tennis ball, though.
If the tennis ball just sits around and is only played with a few hours a week at a non-competitive level, then the new tennis ball can last about three weeks until definite characteristics of the tennis ball have changed.
