(disadvantages)
» Takes 8 to 15 hours to
charge.
This is changing on
newer phones where the battery has a IC board that communicates with
the
phone
fast chargers are
normal.
This is why aftermarket batteries are not recommended.
( Newer phones would
be 2000 or newer that are not Ni-Cad compatible)
» Can be charged about
250
times during useful life. batteries with newer technology
are getting better
results.

about twice as much as NiMH Battery.
Since the early stages of Li-Polymer in the mid-1990's the
technology
has been of specific interest to mobile phone manufactures, as if
allows
for the possibility to design even smaller and lighter handsets than
were
previously possible. The Li-Polymer battery cell does not employ the
hard
metal casing as do conventional nickel metal hydride or lithium ion
batteries.
Instead, the electrodes are covered with a flexible plastic or aluminum
laminate foil. The battery contains no liquid as do traditional
batteries,
but instead the electrolyte is poly-merized into a gel like form. This
allows for batteries to be designed in a variety of sizes and shapes
that
would be impossible using conventional battery cells.
In the Li-Poly batteries available now, the 600 mAh Li-Poly battery
has the same standby and talk time as the 900 mAh Li-Ion, and this
should
increase as technology advances.
“Memory”
(crystalline
formation)
In a batteries cell, Nickel &
Cadmium exists in crystalline form. When “memory” occurs, these
crystals
grow, forming spike or tree like
crystals that cause poor performance. If the cells are not
“conditioned”
crystals can puncture the separator,
leading to the battery shorting or self discharging at a very high rate.
“Memory” occurs when a battery pack
is repeatedly charged without being fully discharged or conditioned
to within one volt per cell (there
are 5 cells in a battery packs that fir the Motorola Flip), or when
left
on a
charger for more than 24 hours.
What kind
of
a battery should I buy? for a Digital phone
Which is best? With newer
digital phones there is not much difference if you use your phone a lot
and cycle
your battery often, you may like
the less expensive Ni-MH, because of replacing batteries more often. If
you
like a lighter phone and do not
mind paying a little more the Lithium Ion battery is the way to go, or
Lithium
Polymer if is in available for your
model phone, these batteries are much lighter and give the same talk
time
and
standby time as the Nickel Metal
Hydride batteries. The more often you can use the battery up before
recharging
the longer the battery will last.
If you frequently use a cigarette
lighter charger, it is wise to charge the battery and disconnect the
charger
when full
leaving the cigarette lighter
charger
attached will keep the battery charging and keep the battery warm, this
will deteriorate the battery cells
and make the battery go bad faster then normal.
All batteries are rated by the
number
of milliamps (mAh) a battery puts out during one hour when it is fully
charged.
The more mAh, the longer the
battery lasts between charges. Check the mAh and “Talk Time /
Standby
Time” in
writing usually what a salesperson
says will be a close guess, these are usually listed in your phones
owners
manual.
What kind
of
a battery should I buy? for a Analog phone
Which is best? If you use
your phone a lot and cycle your battery often, stick with Ni-Cad.
If you
frequently use a cigarette lighter
charger, require more talk time, or can't let your battery totally
discharge
between charges, then its worth
the extra money to get a Ni-MH. All batteries are rated by the
number
of
milliamps (mAh) a battery puts out
during one hour when it is fully charged. The more mAh, the longer
the battery lasts between
charges.

Important
Information
About
Your New
Battery
Please put your battery in a protected covering when not in use.
Before using:
Place your battery in your charger
and charge for a minimum of 14 hours, 24 hours for most new batteries
, most new phones do not include
desktop chargers or charge on the phone so your new battery may need
up to 24 hours please check your
owners manual. Some chargers may show a green light, indicating
charge
completion before that time, but
continue to charge for a full 14 hours. Removing and reinserting
the battery
after several hours may accelerate
the initial charge, in desktop chargers.
You should then be able to use your
phone and battery to make and receive calls. If you do not
receive
the
rated battery capacity during the
initial use, repeat the 14 hour charge process 2 - 3 times.
After this initial charge, you
should
be able to use and charge your new battery as needed. Improved
battery performance may result if
charging is limited to less than 24 hours.
Battery performance will degrade
at extreme temperatures. Do not store your battery where
temperatures
will exceed 60° C (140°
F) or fall below -20° C (-4° F).
Please note, your Ni-Cad battery
has a self discharge rate and without use will loose about 2% of its
charge per day.
Caution:
To prevent injury or
burns.
Do NOT allow metal objects to contact or short circuit the battery
terminals.
Do NOT short circuit the battery
to discharge the battery. Use the proper manufacturers
conditioner
/
charger to discharge and charge
batteries. (Ni-Cad, NiMH, Li-ION)
NEVER pry open a battery
pack.
Opening of a battery pack will void the warranty protection.
NEVER burn or throw into
trash.
Cadmium is a hazardous waste. To help preserve the safety of
our environment, to dispose:
Please take back to your retailer of call your local recycle center.

Additional information Provided by Motorola
Do Motorola batteries have memory effect?
Current Motorola cellular phone batteries virtually do not have any
memory effect. Below is some comparative battery information that may
be
useful.
Lithium Ion (Li Ion) Batteries
Lithium Ion batteries for cellular phones are high energy density
batteries
that provide greater capacity than comparable NiCd or NiMH batteries.
These
batteries are typically about 30% lighter (cell for cell) than NiMH
batteries.
Finally, Li Ion batteries are designed specifically to work with
Motorola
charging systems to provide optimal charge rate and help maximize
capacity
and battery life.
Nickel Metal Hydride (NiMH) Batteries
Nickel Metal Hydride batteries for cellular phones provide the same
voltage as Nickel Cadmium batteries. However, NiMH batteries typically
outperform NiCd under normal consumer conditions and operating
temperatures.
Nickel Metal Hydride batteries are available in several different sizes
to accommodate your cellular needs.
What is the recommended time charge for my battery?
The recommended charge time for an overnight charger, depending on
the battery, can range from 12-24 hours. The recommended charge time
for
rapid chargers, depending on the battery, can be up to four hours. See
your user manual for details.
What happens if I leave the battery in the charger for an extended
period
of time?
Extensive charging may shorten the life of the battery. We recommend
not leaving batteries in a charger for more than 24 hours.
Charging a New Battery
New Batteries are supplied in a totally uncharged state.
To ensure maximum battery performance, a new battery (or battery that has not been used for several months) should be charged for at least 14 hours before use.
A new battery will require several full charge/discharge cycles in order to achieve its optimum performance. A new battery, or battery that has not been used for several months, may cause a premature fully charged indication. Ignore this indication and let the battery charge for several hours.
Your batteries will not charge if they are not matched properly to the phone connection markings (+ and -). Please ensure that you have installed the batteries properly before initiating a charge.
Battery Performance Maintenance
Best battery performance will be achieved when you regularly charge
and discharge batteries.
Battery performance is greatly affected by network coverage and features selected.
If left unused, a fully charged battery will discharge itself in approximately one month.
When not in use, store your battery uncharged in a cool, dark and dry place.
Never leave your battery in extremely high temperatures (over 140° F), for example behind glass in very hot, direct sunlight.
Low Battery Warning
When the battery level is low and only a few minutes of talk time
remain,
a warning signal (two double beeps) will sound, the border of the
battery
symbol will begin to flash, and "Low Battery" will be displayed.
When the battery is completely discharged, your phone will turn off.
Charging Your Battery Using the Travel Charger (For compatible
models
only.)
The travel charger can power the phone and charge a fitted battery.
Ensure the local mains voltage at your location matches that of your
travel
charger. Fit a Motorola original battery onto your phone.
To charge your battery:
1. Attach the correct adapter plug to the travel charger.
2. Connect the travel charger to the phone. The connector is keyed
and can only be inserted one way.
3. Insert the travel charger plug into a suitable mains power socket.
4. A beep-tone is heard and the battery icon flashes when charging
begins. Your phone can either be powered on or off during charging.
Charging Your Battery Using the Desktop Charger (For compatible
models
only.)
The Desktop Charger is an optional accessory that allows you to charge
both the battery fitted in your phone and a spare battery at the same
time,
or in sequential order. Compatibility varies by phone model. Check your
manual for compatibility.
To charge your battery:
1. Connect the travel charger to the desktop charger socket. The
connector
is keyed and can only be inserted one way.
2. Plug the travel charger into a standard mains socket.
3. Insert your phone into the desktop charger.
4. A spare battery can be charged on its own or at the same time as
the battery fitted on your phone. Insert the spare battery into the
desktop
charger. Some desktop chargers charge in sequential order: The battery
inserted into the phone is charged first, then the spare battery is
charged.
Check specific desktop chargers for more information.
Batteries charge in about 2-3 hours depending on the battery.
For maximum NiMH battery charging, you should double the charge time.
Charge times will increase if you make or receive phone calls while charging.
It is normal for batteries to become warm during charging.
It is recommended that you use only Motorola Original™ batteries,
chargers
and other accessories.
