How long do unused CO2 cartridges last

CO2 cartridges are a common power source for various devices, such as airguns, paintball guns, and bike pumps. While they provide a convenient and portable source of power, it's essential to understand their shelf life to ensure optimal performance.

Unused CO2 cartridges can last for several years if stored properly. The key factors that affect their longevity are temperature and moisture. CO2 cartridges should be stored in a cool, dry place away from direct sunlight or extreme heat. Ideal storage temperatures range between 40°F and 70°F (4°C and 21°C). High temperatures can cause the CO2 to expand and weaken the cartridge walls, potentially leading to leaks or explosions.

Moisture can also shorten the lifespan of CO2 cartridges. Exposure to moisture can cause the cartridge to rust, weaken the seals, and compromise the integrity of the cartridge. Hence, it's crucial to store cartridges in a dry environment with low humidity.

Additionally, it's recommended to rotate the cartridges occasionally to prevent any settling or stratification of the CO2 within the cartridge. Gently shaking the cartridge before use can also help ensure proper mixing of the CO2.
