Nokia 8310 - Charging and Discharging

Charging and Discharging

Your 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 discharge
cycles!

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. Unplug the charger when not in use. Do not leave the battery connected to a charger for
longer than a week, since overcharging may shorten its lifetime. If left unused a fully charged battery will discharge
itself 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 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 15°C and 25°C. A phone 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.
