Important Battery Information
•The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operating time (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 approved by the manufacturer. When a charger is not in use, disconnect it from the power source. Do not leave the battery connected to a charger for longer than a week, since overcharging may shorten its life. If left unused a fully charged battery will discharge itself over time.
•(NiMH batteries only) For optimal operation, discharge the battery from time to time by leaving your phone switched on until it turns itself off. You can also use the battery discharge feature of any approved accessory available for your phone. Do not attempt to discharge the battery by any other means.
•Temperature extremes will affect the ability of your battery to charge: allow it to cool down or warm up first.
•Use the battery only for its intended purpose.
•Never use any charger or battery which is damaged or worn out.
•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 back of the battery), for example when you carry a spare battery in your pocket or purse. Short circuiting the terminals may damage the battery or 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 59º F and 77º F (15º C and 25º C). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged. NiMH batteries’performance is particularly limited in temperatures below 14º F
•Do not dispose of batteries in a fire!
•Dispose of used batteries in accordance with any local regulations.
