6. BATTERY INFORMATION

Note: 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 the

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.

For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time to time by

leaving the product switched on until it turns itself off (or by using the battery discharge facility of

any approved accessory available for the product).

Do not attempt to discharge the battery by any other means 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 (59°F and 77°F).

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.

Do not dispose batteries in a fire! Dispose of batteries according to local regulations (e.g. recycling).

Do not dispose as household waste.
