Nokia 2170 - 2. Your Phone’s Battery

4

New batteries must be charged

for at least 24 hours before initial

use, with your phone off.

Note that a new battery’s full

performance is achieved only after

two or three complete charge and

discharge cycles!

WARNING!

Use only batteries, chargers and accessories

approved by the phone manufacturer for use with this particular

model. The use of any other types will invalidate any approval or

warranty applying to the phone, and may be dangerous

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

message 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. See “Batteries” on page 53 for details.
When charging is completed, disconnect the charger from

the AC outlet and from your phone.

Note: When you disconnect the power cord of any accessory,

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

suspended. 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

affect 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

retry. If you still experience charging problems, contact

your dealer and, if necessary, bring your phone in to have

it serviced. 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.

Important battery information

Use only batteries and chargers approved by the phone

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; overcharging may shorten its life.
If left unused, a fully charged battery may completely drain

(discharge) in 1 - 4 weeks.
Never use any charger or battery that is damaged or worn out.
Use the battery only for its intended purpose.
Do not short circuit the battery. Accidental short circuiting can

occur when a metallic object (e.g. coin, clip or pen) causes direct

connection of the two 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, reduces the capacity and lifetime of

the battery. Always try to keep the battery between 41°F and 95°F

(5°C and 35°C). A phone with a hot or cold battery may temporarily

not work (or charge) even if the battery is fully charged. NiMH

battery performance is particularly limited in temperatures below

14°F (-10°C).
Temperature extremes affect the ability of your battery to charge:

allow it to cool down or warm up first.
When the battery is not in use, store it uncharged in a cool, dark

and dry place.
The battery is a sealed unit with no serviceable parts. Do not

attempt to open the case.
It is recommended that you allow your battery to fully discharge

before you recharge it.
The battery can be charged and discharged hundreds of times but

will eventually wear out. When the operating time is shorter than

normal, it is time to buy a new battery.
Do not dispose of a battery in a fire!
Dispose of used batteries in accordance with local regulations.

Recycle!
