How should I take care of my drone batteries?
Avoid storing flight batteries completely full or empty; around 40–60% is a better target for storage.
Store batteries around 40–60% rather than full or empty, avoid extreme heat and cold, and let them cool after a flight before charging. Replace a swollen battery immediately.
Why flight batteries wear out
Most drone batteries are lithium polymer packs, and they age fastest at the extremes: sitting fully charged, sitting empty, baking in heat, or being pushed hard flight after flight. A full charge quietly stresses the chemistry on the shelf, and a deeply drained pack can drop too low to safely recharge. Good habits will not make a battery last forever, but they noticeably slow that decline.
What to do, step by step
- Let a battery cool after landing before you charge it. Charging a hot pack adds heat to heat, so give it time to reach room temperature first.
- Charge on a non-flammable surface and stay nearby. Use the charger made for your batteries, and stop if a pack gets unusually hot, smells odd, or starts to puff.
- For storage longer than a few days, leave packs around 40–60% charged — many smart batteries discharge themselves to that level automatically if you enable the setting.
- Inspect every pack before flight. Retire and safely recycle any battery that is swollen, punctured, or damaged in a crash, even if it still takes a charge.
- Keep batteries out of hot cars and freezing garages, and warm cold packs to room temperature before flying.
