Battery and charger safety
Once charging of your device is complete, unplug the charger from the device and
electrical outlet. Please note that continuous charging should not exceed 12 hours. If
left unused, a fully charged battery will lose its charge over time.
Always keep the battery between 15°C and 25°C (59°F and 77°F) for optimal
performance. Extreme temperatures reduce the capacity 6 and lifetime of the battery.
A device with a hot or cold battery may not work temporarily.
Obey local regulations. Recycle when possible. Do not dispose as household waste.
Do not expose the battery to extremely low air pressure or leave it to extremely high
temperature, for example dispose it in a fire, as that may cause the battery to explode
or leak flammable liquid or gas.
Do not dismantle, cut, crush, bend, puncture, or otherwise damage the battery in any
way. If a battery leaks, do not let liquid touch skin or eyes. If this happens, immediately
flush the affected areas with water, or seek medical help. Do not modify, attempt to
insert foreign objects into the battery, or immerse or expose it to water or other
liquids. Batteries may explode if damaged.
Use the battery and charger for their intended purposes only.
Improper use, or use of unapproved or incompatible batteries or chargers may present
a risk of fire, explosion, or other hazard, and may invalidate any approval or warranty. If
you believe the battery or charger is damaged, take it to a service center or your phone
dealer before continuing to use it. Never use a damaged battery or charger. Only use
the charger indoors. Do not charge your device during a lightning storm.
To unplug a charger or an accessory, hold and pull the plug, not the cord.
Additionally, the following applies if your device has a removable battery:
• Always switch the device off and unplug the charger before removing the battery.
• Accidental short-circuit
