Your Vertu phone is powered by a rechargeable battery.
The full performance of a new battery is achieved only
after two or three complete charge and discharge cycles.
The battery can be charged and discharged hundreds of
times but it will eventually wear out. If you notice that the
talk and standby times are much shorter than normal, you
may need a new battery. Contact Vertu Concierge to
acquire a Vertu approved battery. Use only Vertu
approved batteries and recharge your battery using only
the Vertu approved chargers designed for your Vertu
phone.

Unplug the charger from the AC outlet and your Vertu
phone when not in use. Do not leave your Vertu phone
connected to a charger. Overcharging the battery may
shorten its lifetime. If left unused, a fully charged battery
will lose its charge over time. Temperature extremes can
affect the ability of your battery to charge.
B ATT E R Y C A R E A N D S A F E T Y
Use the battery only for its intended purpose. Never use
any charger or battery that is damaged.
Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object such as a
coin, clip, or pen causes direct connection of the positive
(+) and negative (-) terminals of the battery (the metal
strips on the battery). This might happen, for example,
when you carry a spare battery in your pocket, purse or
bag. Short-circuiting the terminals may damage the
battery and the connecting object.
Leaving the battery in hot or cold places, such as in a
closed car in summer or winter conditions, will reduce the
capacity and lifetime of the battery. Always try to keep the
battery between 15°C and 25°C (59°F and 77°F). If your
battery is very hot or extremely cold, your Vertu phone
may not work temporarily, even if the battery is fully
charged. Battery performance is particularly limited in
temperatures well below freezing.
Caution. Never dispose of batteries in a fire.
Always dispose of batteries according to local
regulations. Please recycle when possible. Do not
dispose of batteries as household waste.
