Do fuel cells have a shelf life?

Fuel cells have a “Best Used By” date printed on the bottom of the can. A fuel cell will often work beyond that date, but if a tool starts to work intermittently it could be because the fuel cell has expired. An expired fuel cell has lost enough internal pressure to degrade its performance.

We recommend buying only enough fuel to complete the job. Always check the date on the bottom of the can before purchasing or using a fuel cell to ensure it is not past the best used by date.
