Battery information■ Charging and DischargingYour phone is powered by a rechargeable battery.Note that a new battery’s full performance is achieved only after two or three complete charge and dischargecycles!The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operatingtime (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.Use only batteries approved by the phone manufacturer and recharge your battery only with the chargers approvedby the manufacturer. Unplug the charger when not in use. Do not leave the battery connected to a charger forlonger than a week, since overcharging may shorten its lifetime. If left unused a fully charged battery will dischargeitself over time.Temperature extremes can affect the ability of your battery to charge.Use the battery only for its intended purpose.Never use any charger or battery which is damaged.Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or pen)causes direct connection of the + and - terminals of the battery (metal strips on the battery) for example when youcarry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or theconnecting object.Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce thecapacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°F). Aphone with a hot or cold battery may temporarily not work, even when the battery is fully charged. Batteries'performance is particularly limited in temperatures well below freezing.Do not dispose of batteries in a fire!Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as household waste.
