Operating lithium batteries in extreme heat most directly risks which problem?
- A.Batteries becoming too cold to deliver current
- B.Accelerated degradation and reduced performance, with swelling risk if overheated
- C.No effect, because heat always improves battery output
Correct answer
B. Accelerated degradation and reduced performance, with swelling risk if overheated
Why
Some warmth helps battery chemistry, but excessive heat accelerates wear and can swell or damage cells. Batteries should be shaded, ventilated, and allowed to cool between flights in hot conditions.
