Using The Batteries

Precautions When Using Batteries

n Never use any charger or battery that is damaged in any way.

n Use the battery only for its intended purpose.

n If you use the phone near the network’ s base station, it uses less power; talk and standby

times are greatly affected by the signal strength on the cellular network and the

parameters set by the network operator.

n Battery charging time depend on the remaining battery charge and the type of battery and

charger used. The battery can be charged and discharged hundreds of times, but it will

gradually wear out. When the operation time (talk time and standby time) is noticeably

shorter than normal, it is time to buy a new battery.

n If left unused, a fully charged battery will discharge itself over time.

n Use only approved chargers. When a charger is not in use, disconnect it from the power

source. Do not leave the battery connected to a charger for more than a week, since

overcharging may shorten its life..

n Extreme temperatures will affect the charging capacity of your battery: it may require

cooling or warming first.

n Do not leave the battery in hot or cold places, such as in a car in summer or winter

conditions, as you will reduce the capacity and life-time of the battery. Always try to keep

the battery at room temperature. A phone with a hot or cold battery may temporarily not

work, even when the battery is fully charged. Li-ion batteries are particularly affected by

temperatures below 0℃(32℉).

n Do not short – circuit the battery. Accidental short-circuiting can occur when a metallic

object (coin, clip or pen) causes a direct connection between the + and – terminals of the

battery (metal strips on the battery), for example when you carry a spare battery in a

pocket or bag.

n Short – circuiting the terminals may damage the battery or the object causing the short –

circuit.

n Dispose of used batteries in accordance with local regulations. Always recycle. Do not

dispose of batteries in a fire.
