Warning: 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.
Your device is powered by a rechargeable battery. The battery intended for
use with this device is BL-5CV. This device is intended for use when
supplied with power from the following chargers: AC-7JV. The exact
charger model number may vary depending on the type of plug. The plug
variant is identified by one of the following: E, EB, X, AR, U, A, C, or UB.
The battery can be charged and discharged hundreds of times, but it will
eventually wear out. When the talk and standby times are noticeably
shorter than normal, replace the battery. Use only Vertu approved
batteries, and recharge your battery only with Vertu approved chargers
designated for this device. Use of an unapproved battery or charger may
present a risk of fire, explosion, leakage, or other hazard.
Do not dismantle, cut, open, crush, bend, deform, puncture, or shred cells
or batteries. In the event of a battery leak, do not allow the liquid to come in
contact with the skin or eyes. In the event of such a leak, flush your skin or
eyes immediately with water, or seek medical help.
Do not modify, remanufacture, attempt to insert foreign objects into the
battery, or immerse or expose it to water or other liquids.
Improper battery use may result in a fire, explosion, or other hazard. If the
device or battery is dropped, especially on a hard surface, and you believe
the battery has been damaged, take it to a service centre for inspection
before continuing to use it.
36
Use the battery only for its intended purpose. Never use any charger or
battery that is damaged. Keep your battery out of the reach of small
children.
Important: Battery talk and standby times are estimates only and
depend on signal strength, network conditions, features used, battery
age and condition, temperatures to which battery is exposed, use in
digital mode, and many other factors. The amount of time a device is
used for calls will affect its standby time. Likewise, the amount of time
that the device is turned on and in the standby mode will affect its talk
time.
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 Customer Service at 03-6738-3955 (or
+81-3-6738-3955) to obtain a Vertu approved battery.

Maximising battery performance

Certain functions in your Vertu phone can be switched off if not in use, to
help maximise your battery performance, for example Bluetooth and 3G.

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. The battery
does not have to be completely discharged before you can recharge it.
Continuously charging 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.
Use chargers indoors.
