Modern household batteries - AA, AAA, 9V, C and D cells - are usually alkaline or zinc carbon.
Alkaline and zinc carbon batteries are expensive to properly recycle, and usually cost more to reprocess than the market value of the recovered materials. Most places charge to take them, or take them for free along with other more profitable materials.
Some yards might pay for them if they're mixed in with shredder scrap.
