The lifespan of whipped cream chargers can be broken down into two aspects: the gas itself and the charger container.

• Nitrous Oxide (N2O): The gas inside the charger, nitrous oxide, has an indefinite shelf life if stored properly. It's a stable gas and won't degrade over time.
• Charger Container: The metal container that holds the gas has a recommended shelf life of around 5-7 years. After this period, the seal on the charger might begin to weaken, potentially leading to small leaks and reduced effectiveness.

Here are some storage tips to maximize the lifespan of your chargers:

• Cool and Dry:Store your chargers in a cool, dry place. Heat can cause the metal to expand and weaken the seal.
• Out of Direct Sunlight: Avoid storing chargers in direct sunlight, as this can also contribute to heat buildup.
• Puncture-Free: Ensure the chargers haven't been punctured or damaged, as this can compromise the seal and lead to leaks.
