Two clocks, one platform
Every CEW in a department is running two clocks at once: the weapon itself has a manufacturer service-life warranty, and every cartridge loaded in it or spared on the belt has its own separate expiration date. Miss either one and the officer is carrying a duty item that is out of certification.
The industry standard for TASER 7 has been a five-year warranty, and TASER 10 launched with a ten-year warranty; older X26P and X2 platforms carried five-year warranties as well. Cartridges typically carry a five-year shelf life from the date of manufacture, with the expiration printed on the base. Both dates matter, and neither is optional if the department wants a defensible use-of-force record.
What "expired" actually means for a CEW
Unlike a firearm, a CEW is an electronic device with a battery, capacitors, and a serialized log. The manufacturer warranty is not a promise the device will fail on day 1,826 — it is the point past which the manufacturer will no longer certify or repair the device. In practice, out-of-warranty CEWs stay in service in many departments longer than they should, because "it still works" and budget is what it is.
The exposure is not that the device stops firing. It is that when a plaintiff's attorney or an internal reviewer looks at the after-action, they will find a use-of-force event conducted with a device that was outside the manufacturer's certified service life. That is a very hard fact to defend around, no matter how the deployment actually went.
For cartridges, "expired" is more mechanical: propellant, primer, and probe integrity degrade over time. Aged cartridges can misfire, deploy erratically, or fail to make contact. The failure mode is a probe deployment that doesn't achieve NMI (neuromuscular incapacitation) — the officer transitions to a higher force option unnecessarily.
Spark tests: the routine that catches drift
Best-practice CEW policy requires a documented spark test at a defined cadence — daily at shift start for many agencies, at minimum weekly. The spark test verifies that the device is powered, that the battery is holding, and that the arc is present. It does not verify cartridge integrity (cartridges cannot be re-used after firing), which is why cartridge tracking is separate from device tracking.
The value of a spark test log is not the individual test — it is the pattern. A CEW that starts intermittently failing spark tests is a device on its way to a failure in the field. Without a searchable log, that pattern is invisible until the failure happens on a call.
What a CEW policy should include
Actual policy language should be reviewed by your city or county attorney. This is the working outline that consistently survives review.
1. Issue and assignment
- Every CEW is assigned to a named officer, with serial number, model, manufacture date, warranty expiration date, and firmware revision recorded at issue.
- Every cartridge is tracked individually by serial number, with model, manufacture date, and expiration date recorded at issue and at every reload.
- Officer acknowledges training currency, spark test cadence, and care instructions electronically at issue.
2. Spark tests and inspection
- Spark test at the cadence defined by policy (daily or weekly), with pass/fail logged to the device record.
- Battery pack status checked at every spark test; battery packs replaced per manufacturer guidance and tracked by their own dates.
- Any spark test failure removes the device from duty pending armorer inspection.
- Cartridges are visually inspected at the same cadence; any dented, corroded, or expired cartridge is removed and replaced.
3. Service life and replacement
- Replacement CEWs are procured to arrive before in-service devices reach warranty expiration.
- Cartridge replacement is ordered at least 60 days before expiration.
- Out-of-warranty CEWs are removed from patrol service on or before the warranty expiration date. Where budget requires a bridge, they may be reallocated to training use with a documented policy decision on the record.
4. Deployment and after-action
- Every deployment (against a subject, unintentional, or training) is logged with device serial number, cartridge serial numbers, deployment time, and duration.
- Device deployment logs are pulled via the manufacturer platform and reconciled with the department's tracking system after every deployment.
- Use-of-force reports link directly to the CEW serial and cartridge serials involved, so the manufacture date, warranty status, and spark test history are visible in the after-action record.
5. Reporting and audit
- Monthly report of CEWs within 12 months of warranty expiration and cartridges within 90 days of expiration.
- Quarterly summary of spark test compliance by officer and by device.
- Full audit trail preserved indefinitely per serial number — device and cartridge.
Why paper and spreadsheets fail at this
CEW tracking is where manual systems collapse most obviously, because it is the item with the most moving parts: a serialized device, one or two loaded cartridges, spare cartridges on the belt, battery packs, a spark test log, and a manufacturer deployment log that lives in a completely separate platform. Tying all of that together in a spreadsheet is possible in theory and almost never done in practice.
Predictable failure modes:
- Warranty dates go unwatched. The CEW keeps being carried past its warranty because the spreadsheet lives on the armorer's laptop and nobody scans it.
- Cartridge expirations are invisible. Nobody tracks cartridges individually; the officer loads whatever is in the spare box; expired cartridges get carried.
- Spark test logs are on paper. They get missed, backfilled, or thrown away.
- After-action reconstruction is manual. When counsel asks "what was the last spark test on the device used in this deployment," the answer requires digging.
- Manufacturer deployment logs never make it into the record. The data exists on the vendor platform and is never reconciled with the department's tracking system.
What roster-integrated tracking looks like
A department running an integrated system should be able to answer these in a single query:
- Which CEWs are within 12 months of warranty expiration, by assigned officer?
- Which cartridges, by serial and location, are within 90 days of expiration?
- Which officers have missed a spark test in the last 30 days?
- What is the full spark-test, battery, and deployment history for device #TAS-00841?
- How many replacement CEWs and cartridges need to be procured next fiscal year, given current expirations and historical deployment rate?
How APB360 handles CEW and cartridge tracking
APB360 treats each CEW and each cartridge as a serialized, date-driven asset — assigned to an officer, tied to warranty and manufacture dates, with spark test history, battery status, and deployment logs stored as first-class fields. Alerts fire by SMS or email to the officer, supervisor, and armorer when a device or cartridge enters your configured warning window. Use-of-force reports link to the specific device and cartridges deployed, so the after-action record includes the full lifecycle context automatically.
When leadership, training staff, or legal counsel asks about the department's CEW accountability, the answer is a live report — not a rebuilt binder.
Bottom line
A CEW is the most heavily-documented single item on an officer's belt, and it is where accountability failures produce the most visible consequences. The departments that don't have those failures are the ones running a system that watches every warranty, every cartridge date, every spark test, and every deployment as a linked set of records. If any of those pieces lives in a separate spreadsheet or on paper, the failure mode is already in place; only the timing is unknown.
