DJI Agras T40 Warranty: Complete Coverage, Parts, Battery & Claim Guide
🇺🇸 U.S.A. FIRST — DJI Agras T40 Factory Warranty, Battery, Spray System, Spreading System, Remote Controller & Claim Process
Updated September 11, 2026.
The DJI Agras T40 is one of the clearest examples of why Agras warranty coverage should be read by component rather than summarized as “one year.” DJI’s current T40 Main Components Warranty Periods List gives many major aircraft systems—including the frame, propulsion motor, ESC, radar, aircraft electronics and power-distribution hardware—12 months under the standard schedule. But the same document gives selected high-wear spraying components only 3 months, propellers/hoses/cables only 15 days, and selected spreading-system components 6 months.
The intelligent flight battery adds a second dimension: 12 months or 1,500 charge cycles, whichever comes first. For a high-utilization agricultural fleet, the cycle limit may become the controlling warranty threshold before the calendar year expires.
DJI lists many T40 major aircraft components at 12 months, including the FPV module, radar modules, RF board, aerial-electronics module, spraying module, distribution boards, vision sensors, RTK antenna, ESC, propulsion motor and frame. Selected spray wear components such as the pump, centrifugal spray bar, flow meter and liquid-level module are 3 months. Cables, propellers/propeller clamps and hoses are 15 days. The intelligent flight battery is 12 months or 1,500 cycles, whichever comes first.

Complete T40 Major Aircraft Warranty Table
DJI’s current U.S./standard T40 Main Components Warranty Periods List assigns 12 months to the following aircraft components:
| T40 aircraft component | Warranty period |
|---|---|
| FPV Module | 12 months |
| Omnidirectional Radar Module | 12 months |
| RF Board | 12 months |
| Aerial-Electronics Module | 12 months |
| Spraying Module | 12 months |
| Cable Distribution Board Module | 12 months |
| Dual Vision Sensors | 12 months |
| Aircraft Arm In-Position Detector Signal Cable | 12 months |
| Air-Cooled Heat Sink | 12 months |
| Power Distribution Board Module | 12 months |
| RTK Antenna Module | 12 months |
| Backward Vision Radar | 12 months |
| ESC | 12 months |
| Propulsion Motor | 12 months |
| Frame | 12 months |
Important Correction: The Current T40 Frame Warranty Is Listed at 12 Months
Older third-party summaries of Agras warranty sometimes describe the airframe as a notable exception or imply that agricultural frames are not covered. DJI’s current T40 Main Components Warranty Periods List for the standard schedule explicitly lists Frame — 12 months.
This is exactly why warranty articles should cite the current model-specific DJI table rather than applying an older rule of thumb across generations.
T40 Spraying Wear Components — 3 Months
DJI separates the high-level Spraying Module from the individual wear components exposed to liquid, vibration, chemical residue and repeated operation.
| T40 spraying/wear component | Warranty period |
|---|---|
| Load Sensor Module | 3 months |
| Centrifugal Spray Bar Assembly | 3 months |
| Pump | 3 months |
| Flow Meter Module | 3 months |
| Spraying Adapter Module | 3 months |
| Liquid Level Meter Module | 3 months |
This means a failed pump at month five cannot be evaluated by pointing to the 12-month Spraying Module entry. The pump has its own published period.
T40 15-Day Components
The T40 warranty list assigns only 15 days to several high-wear or external components:
| Component | Warranty period |
|---|---|
| Cable (wear-parts category) | 15 days |
| Propeller & Propeller Clamp | 15 days |
| Hose | 15 days |
| Other accessories under the aircraft category | 15 days |
| Packaging materials | No warranty |
Short coverage does not mean these parts are unimportant. It means the warranty structure recognizes their exposure to wear, handling and field damage.
T40 Intelligent Flight Battery Warranty
DJI lists the T40/T20P intelligent flight battery at 12 months or 1,500 charge cycles, whichever comes first.
If a T40 battery is nine months old but has reached 1,500 charge cycles, the cycle threshold arrives before the 12-month threshold. If it is 12 months old at only 700 cycles, the calendar threshold arrives first.
For a high-volume operator, cycle allocation across the battery fleet can therefore affect warranty utilization. Rotate batteries intentionally, monitor health and preserve serial-level records.
T40 Charger & Battery-Station Warranty
DJI’s standard T40 list gives:
- Intelligent Charger (T20P/T40): 12 months
- Battery Station AC Module: 12 months
- Intelligent Flight Battery: 12 months or 1,500 cycles
- Other accessories / packaging: no listed warranty
Do not assume a damaged cable, charger main assembly and battery all share identical warranty logic.
T40 Remote Controller Warranty
The T40/T20 remote-controller category gives 12 months to several core modules:
| Remote-controller component | Warranty period |
|---|---|
| SDR Board | 12 months |
| Core Board Module | 12 months |
| GPS Board | 12 months |
| Button | 12 months |
| Type-C Socket | 12 months |
| Type-A Socket | 12 months |
| 65W Portable Charger | 12 months |
| RTK Dongle Antenna Module | 12 months |
| Remote Controller Battery | 12 months |
| Other accessories | No warranty |
T40 Spreading System Warranty
The T40 spreading system splits durable drive/control modules from high-wear structure and cables.
| T40 spreading component | Warranty period |
|---|---|
| Control Module | 6 months |
| Servo Module | 6 months |
| Reduction Gearbox | 6 months |
| Structural components | 15 days |
| Cables | 15 days |
| Water Tank / listed tank component | 15 days |

U.S./Standard T40 Warranty vs EU/Turkey/Georgia
DJI publishes a separate T40 schedule for the EU, Turkey and Georgia. That schedule lists many main aircraft/controller components at 24 months rather than 12, several wear parts at six months rather than three and short-duration parts at 30 days rather than 15. The intelligent flight battery remains subject to a 12-month/1,500-cycle limit in that schedule.
This proves a critical point: warranty period is regional. Do not import a duration from a European table into a U.S. warranty claim.
When Does the T40 Warranty Start?
DJI Agriculture states that the warranty period starts on the delivery date. Without an invoice or other valid proof of purchase, DJI provides an alternate calculation beginning 90 days after the shipping date shown on the product unless another agreement applies.
What Is Covered Under T40 Factory Warranty?
The DJI Agriculture limited warranty covers the T40 component against material and workmanship defects under normal use during the applicable period, provided the aircraft is used according to DJI’s manuals, safety guidelines, specifications, in-app notifications and service communications.
What Is Not Covered?
DJI Agriculture’s exclusions include collision and burning absent a manufacturing defect, unauthorized modification/disassembly, incorrect installation/use, water ingress from incorrect operation, unauthorized circuit modification, improper battery/charger use, harsh-environment damage, electromagnetic interference, wireless interference, exceeding safe takeoff weight, compatibility/reliability problems involving uncertified third-party parts, low-power/defective-battery misuse, flights outside product instructions, tampered labels/serial numbers, natural disasters, stolen/missing equipment and failure to provide flight logs required for accident analysis.
If My T40 Crashes, Is the Airframe Covered?
The frame having a 12-month warranty does not mean DJI will replace a frame damaged in any crash for one year. The frame is covered against qualifying defects during its period. Collision damage resulting from pilot error or an external impact is different.
The correct sequence is:
Why Flight Logs Matter for T40 Claims
DJI Agriculture explicitly references accident-data analysis. After a crash or in-flight malfunction, preserve:
- flight logs,
- remote-controller logs,
- the installed battery identity,
- warning/error screenshots,
- photos of damage before disassembly,
- mission payload and takeoff weight information,
- weather and field conditions,
- maintenance/repair history.
Does the T40 Have DJI Care Refresh?
Do not confuse the T40 factory warranty with consumer DJI Care Refresh. Care Refresh is an optional program for supported camera-drone/handheld products. The T40 follows DJI Agriculture’s after-sales policy and T40 component warranty schedule.
How to Prepare a T40 Warranty Claim
- Ground the aircraft if continued operation is unsafe.
- Identify the exact component.
- Check DJI’s current T40 warranty list.
- Confirm delivery date and battery cycle count.
- Preserve flight/controller logs.
- Take photos and video before opening or replacing parts.
- Save error codes and app warnings.
- Locate invoice and serial numbers.
- Record payload, environment and incident description.
- Contact the authorized DJI Agriculture service channel.
- Follow service instructions before unauthorized disassembly.
- Back up data.
- Review warranty diagnosis.
- If the part is expired/excluded, choose paid repair or OEM replacement based on downtime.
T40 Warranty Claim Checklist
| Item | Use |
|---|---|
| Proof of purchase | Establish warranty start and authorized source |
| T40 serial number | Aircraft identity / region |
| Battery serial + cycle count | Time/cycle eligibility |
| Flight logs | Accident/root-cause analysis |
| Error codes | Module-level diagnosis |
| Photos/video | Physical evidence before repair |
| Maintenance history | Evidence of proper use |
| Third-party modifications | Determine causal relevance |
What Happens After a T40 Warranty Replacement?
Under DJI Agriculture policy, a free replacement component receives the remaining original warranty period. The replacement does not automatically restart the full component period.
For paid repair/replacement of a main component, the applicable period is generally the original remaining warranty or 90 days, whichever is longer, except short-duration 15/30-day categories retain their shorter treatment.
Common T40 Warranty Mistakes
- Using an old third-party statement instead of DJI’s current T40 component list.
- Believing the T40 frame has no warranty despite the current standard table listing 12 months.
- Assuming the pump has the same 12 months as the Spraying Module.
- Ignoring the 1,500-cycle battery limit.
- Assuming a propeller has one-year coverage.
- Mixing EU 24-month periods into a U.S. claim.
- Deleting logs after an incident.
- Continuing to fly after repeated ESC/motor/radar warnings.
- Opening components before documenting a potential defect.
- Assuming crash damage equals frame-warranty coverage.
- Assuming DJI Care Refresh automatically applies.
- Assuming a replacement part restarts the warranty clock.
T40 Spare-Parts Strategy During the Warranty Period
Warranty can reimburse or repair a qualifying defect; it cannot guarantee that an aircraft is available for tomorrow’s spray window. A working T40 fleet should identify the components whose downtime cost exceeds the cost of stocking a spare.
Depending on operation size, consider access to:
- propellers and hardware,
- hoses and spray lines,
- pump/flow components,
- selected signal cables,
- landing/structural wear parts,
- adequate healthy intelligent batteries,
- charger/generator contingency,
- critical propulsion parts where justified.

Final Takeaway
The current DJI Agras T40 warranty schedule is unusually useful because it makes the component hierarchy explicit. Major flight systems—including the frame—are listed at 12 months, while pumps and other spray wear hardware fall to three months, spreading drive/control parts to six months and propellers/hoses/certain cables to 15 days. The battery is governed by both time and cycle count.
That makes the correct warranty question not “is my T40 still under warranty?” but “which T40 component failed, what period applies to that component, and does the evidence point to a covered defect?”
