Nokia 2180 manual Important battery information

Your battery can be charged and discharged hundreds of times but it will eventually wear out. When the operating time is noticeably shorter than normal, and reconditioning fails to extend its life, it’s time to buy a new battery.

Important battery information

For good operation times, discharge the battery from time to time by leaving your phone switched on until it turns it- self off or by using the battery discharge facility of any approved accessory available for your phone. Do not at- tempt to discharge the battery by any other means.

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 at room temperature.

When the battery is not in use, store it uncharged in a cool, dark and dry place.

Temperature extremes will affect the ability of your battery to charge: it may require cooling or warming first.

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 terminal may damage the battery or the con- necting object.

Use the battery only for its intended purpose. Never use any charger or battery that is damaged or worn out.

Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the capac- ity and lifetime of the battery. Always try to keep the battery between 59°F and 77°F (15°C and 25°C). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged. NiMH battery performance is particularly limited in temperatures below 14°F (-10°C).
