Nokia 2180 - 2. Your Phone’s Battery

4

New batteries must be charged for

at least 24 hours before initial use,

with your phone off. A new battery’s

full performance is achieved only

after two or three complete charge

and discharge cycles!

IMPORTANT: Use only batteries approved by the phone

manufacturer and recharge your battery only with the

chargers approved by the manufacturer. See “Important

battery information” on page 6.

When should you charge?
With only a couple of minutes of talk

time remaining, your phone will warn

you with a tone and %$77(5< /2: will

appear on your display.
Once all the power has been drained

from your battery, you’ll hear three beeps with the mes-

sage 5(&+$5*( %$77(5< on your display. At this point,

your phone will switch itself off.

To charge or recharge your battery

You can charge your

phone while it is on or

off. Simply connect

the lead from the

charger to the bottom

of your phone or

place it on a charging

stand. Then connect

the charger to a standard 120V AC outlet.
When the battery begins charging,

the battery strength indicator on the

right side of the display will scroll

and your phone will beep once.

When is charging complete?

To allow the battery to completely charge, wait

for the charge indicators to stop scrolling. At this

point, your phone is considered fully charged.

However, a slight increase in charge may occur

if the phone is left connected to the charger, this

is called “trickle charge.”
Charging times depend on which type of battery and

charger is used. For approximate charging and operating

times, see “Accessories” on page 58.
When charging is completed, disconnect the charger from

the AC outlet and from your phone.
Note: When you disconnect the power cord of any acces-

sory, grasp and pull the plug, not the cord.

Can you make calls while charging?
Yes, you can. But your battery will not charge while a call

is in progress. Charging will resume when you end the call.

What if charging fails?
If your phone displays 127 &+$5*,1*, charging is sus-

pended. Make sure the battery is connected to an

approved charging device and that the battery is at room

temperature. Extreme temperatures, hot or cold, can af-

fect your battery’s performance and prevent charging.
If charging still fails, disconnect the charger from your

phone. Then reconnect the charger to your phone and re-

try. If you still experience charging problems, contact your

dealer and, if necessary, bring your phone in to have it ser-

viced. Also remember to bring in your battery and charger.

To discharge your battery
There are two ways to properly discharge a battery. You

can leave your phone on while your battery drains, finally

turning itself off. Or you can use the discharge facility of

any approved accessory equipped with this feature.

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).

The battery is a sealed unit with no serviceable parts. Don’t

attempt to open the case.
Don’t dispose of a battery in a fire! Dispose of used batter-

ies in accordance with local regulations. Recycle!
Using your phone near the network’s base station con-

sumes less power. Keeping the antenna fully extended

whenever possible maintains the connection to the net-

work with less power.
Your phone switches itself off if the operating temperature

of your phone exceeds 158°F/ 70°C. Also, it switches off

after 12 hours if connected to a Compact Handsfree Car

Kit.
When the battery charge is very low, your phone reduces

the power at which it transmits radio signals to extend the

talk time. This may affect the quality of calls.
In some vehicles, the ignition must be on in order to charge

your phone with the Mobile Charger.
