Battery Safety & Maintenance Guidelines: To ensure your safety and extend battery lifespan, please adhere to the following key tips

1. Essential Safety Precautions

  • Charging Do’s & Don’ts: Always stay present while charging. Use only original/certified chargers (non-designated ones may cause short circuits/swelling). Charge in a dry, ventilated space (5℃-35℃), keep away from flammables/soft surfaces (e.g., carpets). Avoid charging in heavy rain/thunderstorms.
  • Pre-Use & Condition Checks: Inspect for cracked casings, leaks, or dirty/rusty electrodes—stop use if issues arise. Never burn, expose to high heat, disassemble, or strike the battery; keep away from metal items (keys, coins) to prevent short circuits. If wet, air-dry thoroughly before charging.

2. Easy Maintenance Tips

  • Smart Charging Habits: Recharge when the tool slows down (low power sign). Unplug 1-2 hours after full charge; never over-charge or fully drain the battery.
  • Storage & Basic Care: Store at 10℃-25℃ (humidity <60%) with 40%-60% charge; check/recharge every 3 months if unused. Wipe electrodes regularly with a dry cloth. Pause 1-2 minutes every 15-20 minutes during heavy use to cool down.
