Learn how to identify an expired TASER cartridge, safely replace it, and dispose of the old one. Keep your device ready with proper storage and spare cartridges.
Quick Answer
If your TASER cartridge has passed its expiration date, do not use it for live deployment. Replace it immediately with a fresh live cartridge, and dispose of the expired one according to local electronic waste guidelines. Keep spare cartridges on hand to avoid being unprotected.
Why TASER Cartridges Expire and What That Means
TASER cartridges are pressurized with compressed nitrogen and contain conductive wires and probes. Over time, the seals can degrade, and the nitrogen may slowly leak, reducing deployment reliability. The expiration date printed on the cartridge is the manufacturer's guarantee that it will perform as intended. Using an expired cartridge risks a dud or partial deployment when you need it most.
How to Check Your Cartridge's Expiration Date
Look for the date printed on the cartridge body or packaging. It is usually a month and year (e.g., 01/2026). If you cannot find a date or the date has passed, treat the cartridge as expired. Some cartridges also have a tamper-evident seal; if that is broken, replace the cartridge immediately regardless of the date.
Replacing an Expired TASER Cartridge
To replace, first ensure your TASER device is unloaded and the safety is on. Remove the expired cartridge by pressing the release button or sliding it out (varies by model). Insert a new live cartridge until it clicks securely. Test the new cartridge in a safe direction (point it at a safe backstop) to confirm function, then reload the device. Always keep a spare like the Two-Pack of Live Cartridges for TASER X1/X26P/X26C/M26C stored in a cool, dry place so you have a fresh replacement ready.
Diagnosis: Expired Cartridge Check
- Symptom: Your TASER device fails to deploy probes during a test fire, or the cartridge seal appears loose or has a broken tamper-evident ring. Do not rely on this cartridge for self-defense.
- Likely Cause: The cartridge has passed its expiration date, causing nitrogen pressure loss or seal failure. Check the printed date immediately.
- Corrective Action: Unload the expired cartridge, insert a fresh live cartridge, and perform a safe test fire to confirm function. Replace with a new live cartridge from a spare pack.
- Stop or Choose Another Option: If you do not have a spare cartridge, do not carry the TASER device. Order a replacement or use a different personal protection device until you can restock. Never carry a device with an expired or untested cartridge.
Recommended Replacement Cartridges
