How should performance planning change as a battery ages and its internal resistance rises?
- A.Expect the same endurance as when the battery was new
- B.Expect reduced endurance, more voltage sag, and earlier warnings
- C.Expect improved endurance because the battery is broken in
Correct answer
B. Expect reduced endurance, more voltage sag, and earlier warnings
Why
Aging cells deliver less usable capacity and sag more under load. Planning shorter flights and retiring batteries that swell, overheat, or sag excessively keeps performance predictable.
