How will the battery be affected if the temperature drops below the UA's optimal operational temperature range?

• A. Battery life will shorten
• B. Battery life will lengthen
• C. No effect
• D. Battery may overheat

Answer: (A)

Cold temperatures slow the chemical reactions inside a battery and raise its internal resistance. That means the battery can’t deliver energy as efficiently under a given load, so usable capacity drops and the flight time you get is shorter. You’ll often see a lower voltage under load too, which further reduces performance. So, when the temperature falls below the UA’s optimal range, the battery life shortens. It won’t lengthen, and overheating isn’t a concern from the cold—overheating relates to hot conditions. Keeping batteries warm or preheating them helps maintain better performance.
