Q: How to maintain battery performance during long hours of daily operation (e.g., 8–10 hours of continuous delivery)?

A: ① Avoid fully draining the battery (recharge when remaining power is 20%–30%); ② Keep the battery at 15–35℃ (avoid extreme heat/cold); ③ Use the original charger for 4–8 hours per charge (do not overcharge); ④ Check battery connections weekly for looseness/corrosion.
