BATTERY INFORMATION
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
stand-by 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.
Charging and discharging
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.
Battery care and safety
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.

The vehicle charger is not supplied with your
Vertu phone. It is available for purchase from
all Vertu Stores.
The vehicle charger recharges your Vertu phone
battery quickly and safely from a standard 12 or 24
volt (DC) vehicle cigarette lighter outlet.
Only use the vehicle charger specifically designed
for use with your Vertu phone.
Never attempt to use a vehicle charger if it has
been damaged.
Only use the vehicle charger in a stationary
vehicle.
The time taken to charge your battery depends on
its existing charge. It takes approximately 90
minutes to charge the battery. You can use your
phone normally during the charging process.
