A drone battery is a $150–300 consumable with a hard lifespan. We publish cycle counts and tested capacity for every pack we sell, so the hidden cost is never hidden.
Ask a marketplace seller for the battery cycle count and watch the listing go quiet. Yet a DJI intelligent battery is rated for roughly 200–400 cycles before capacity drops below 80% — meaning a "barely flown" drone can arrive with a pack that's effectively spent. At AST-Drones, battery data is tested, published, and covered by the warranty.
| Cycles | Expected capacity | Our grade impact |
|---|---|---|
| 0–30 | 95–100% | Eligible for Like New / CPO |
| 31–80 | 90–95% | Eligible for Excellent |
| 81–150 | 80–90% | Good grade maximum; priced accordingly |
| 150+ | < 80% | Not sold with airframes — recycled or sold explicitly as spares |
Cycle count is a proxy; capacity is the truth. Two 60-cycle batteries can test at 96% and 83% depending on storage and charging habits — which is why every pack gets a physical capacity run, not just a chip read. The tested figure appears on your unit's report and anchors its warranty threshold.
Buying a drone for demanding work? Pair a warrantied airframe from the catalog with certified batteries — or ask about fresh-pack bundles at checkout.
In the DJI Fly/GO 4 app: connect the drone, open battery settings, and the cycle count displays per pack. For a deeper read (cell voltages, health %), desktop tools like DJI Assistant 2 expose more. Our quote form links a step-by-step guide.
Yes, if tested capacity holds ≥85% and the price reflects it — that's why Good-grade units cost 40–55% less. The trap is paying Excellent-grade money for a 100-cycle pack, which published reports make impossible here.
Yes — if a pack drops below its grade's capacity threshold within the warranty window, we repair or replace it. Normal gradual aging over months is excluded.
