appears to dry out and operate normally,
internal parts can slowly corrode and pose a
safety hazard.
• Always keep the battery between 15 °C and

cold), fire, or other hazards such as a
cooking surface, iron, or radiator.
• Never use any damaged battery.
• Only use the battery for its intended phone.

charger. Use of an unqualified battery
charger may present a risk of fire,
explosion, leakage, or other hazard. If you
are unsure about whether a charger is
qualified, contact customer support.
• Do not short-circuit the battery or allow
metallic conductive objects—such as keys,
coins, or jewelry—to contact the battery’s
terminals.

qualified battery. Use of an unqualified
battery may present a risk of fire,
explosion, leakage, or other hazard. If you
are unsure about whether a replacement
battery is compatible, contact customer
support.
• Promptly dispose of used batteries in
accordance with local regulations and
recycle if possible. Do not dispose as
household waste.
