Professional-grade bat care can extend a bat's lifespan by 3-5 seasons. Regular oiling with raw linseed oil helps maintain the wood, while proper knocking-in prepares the bat for match use. Store bats in controlled conditions (15-25°C at 50-60% humidity) to prevent warping. Minor cracks can be repaired with wood glue, and surface wear can be addressed with fine sandpaper. Regularly check your bat's performance through sound tests and edge thickness measurements. Rotating between multiple bats can significantly extend their usable lives.
