Battery care
General safety guidelines
•
Do not disassemble or open the battery.
•
Do not crush, bend, deform, puncture, or
shred the battery.
•
Do not attempt to insert foreign objects into
the battery.
•
Do not immerse the battery or expose it to
water or other liquids. Even if a battery
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
25°C (59°F and 77°F). Do not expose the
battery to extremes of temperature (heat or
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.
•
Only use the battery with a qualified 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.
•
Replace the battery only with another 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.
•
Supervise all battery usage by children.
•
Avoid dropping the phone or battery. If the
phone or battery is dropped, especially on a
hard surface, an internal short-circuit can
occur and pose a safety hazard. If you
suspect battery damage, take it to a service
center for inspection.
•
Improper battery use may result in a fire,
explosion, or other hazard.
