Are
your batteries old or refurbished? What is the meaning of "Third
Party"? |
 |
Most of our
batteries are brand new third party products. Brand new means
new case and new cells. Third party means they are not original
batteries, but we fully guarantee our batteries meet or exceed
OEM specifications, since our batteries also use Japanese cells
and some items have more capacity than original ones.

How to
care and use battery? |
|
|
Your new battery
comes in a discharged condition and must be charged before use.
Upon initial use (or after prolonged storage period) the battery
may require two to three charge/discharge cycles before
achieving maximum capacity.
If the battery is not going to be used for more than a month, it
is recommended that it be removed from the device and stored in
a cool, dry, clean place.
It is normal for a battery to become warm during charging and
discharging.
A charged battery will eventually lose its charge if unused. It
may therefore be necessary to recharge the battery after a
storage period. |

What
should I pay attention to? |
|
|
Do not
short-circuit a battery. A short-circuit may cause damage to the
battery.
Do not drop, hit or otherwise abuse the battery as this may
result in the exposure of the cell contents, which are
corrosive.
Do not expose the battery to moisture or rain.
Keep battery away from fire or other sources of extreme heat. Do
not incinerate. Exposure of batteries to extreme heat may result
in an explosion. |

What
is the "Memory Effect"? |
|
|
Ni-Cad batteries
suffer from what's called the "memory effect" This means that if
a battery is continually only partially discharged before
re-charging, the battery "forgets" that is has the capacity to
further discharge all the way down. To illustrate: If you, on a
regular basis, fully charge your battery and then use only 50%
of its capacity before the next recharge, eventually the battery
will become unaware of it's extra 50% capacity which has
remained unused. Your battery will remain functional, but only
at 50% of its original capacity. The way to avoid the dreaded
"memory effect" is to fully cycle (fully charge and then fully
discharge) your battery at least once every month. Batteries can
be discharged by unplugging the device's AC adapter and letting
the device run on the battery until it ceases to function. This
will ensure your battery remains healthy. Ni-Mh and Li-Ion
batteries do not suffer the memory effect. |

Can I
upgrade my current battery to a newer Chemistry? |
|
|
NiCad, Ni-Mh and
Li-ion are all fundamentally different from one another and
cannot be substituted unless the device has been pre-configured
from the factory to accept more than one type of rechargeable
battery. The difference between them stems from the fact that
each type requires a different charging pattern to be properly
recharged. Refer to your owner's manual to find out which
rechargeable battery types your particular device supports. |
|

7. |
My New
Battery Isn't Charging, what's going on? |
|
|
New batteries are shipped in a discharged condition and must be
charged before use. We generally recommend an overnight charge
(approximately twelve hours). Refer to your user's manual for
charging instruction. Rechargeable batteries should be fully
charged and then fully discharged 2 to 4 times initially to
allow them to reach their full capacity. (Note: It is perfectly
normal for a battery to become warm to the touch during charging
and discharging).
New batteries are
hard for your device to charge because they have never been
fully charged and are therefore unformed. Sometimes your
device's charger will stop charging a new battery before it is
fully charged. If this happens, simply remove the battery from
your device and then re-insert it. The charge cycle should start
again. This may happen several times during your first battery
charge. Don't worry; it's perfectly normal.
*
If your
battery still does not work well after you try the above steps,
we strongly suggest you update your notebook's BIOS.
Our battery is
generic, every battery is compatible to lots of notebook models
and produced with latest version of firmware, so the battery has
no way to work well on notebooks with old version of BIOS. In
most cases, updating the notebook's BIOS will solve the problem.

How
can I maximize battery performance? |
|
|
Breaking In New Batteries
New batteries come in a discharged condition and must be fully
charged before use. It is recommended that you fully charge and
discharge your new battery two to four times to allow it to
reach its maximum rated capacity.
Keep Your Batteries Clean
It's a good idea to clean dirty battery contacts with a cotton
swab and alcohol. This helps maintain a good connection between
the battery and your laptop.
Exercise Your Battery
Do not leave your battery dormant for long periods of time. We
recommend using the battery at least once every two to three
weeks. If a battery has not been used for a long period of time,
perform the new battery break in procedure described above.
Power Management
To get maximum performance from the battery, fully optimize the notebooks power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it’s not used and causing the machine to go into sleep mode when inactive. The notebook user’s guide will provide information relating to specific power management features. It may also be necessary to update the BIOS of the notebook in order to achieve maximum performance especially if the original battery has a lower power capacity (mAH). Please visit the notebook manufacturer’s website for information regarding BIOS updates.

What
are battery ratings? |
|
|
There are two
ratings on every battery: Volts and Milliamp-hour (mAh). The
voltage of the new battery should always match the voltage of
your original. Some of our batteries will have higher amp-hour
ratings that the original battery found in your device. This is
indicative of a longer run-time (high capacity) and will not
cause any incompatibilities. Remember: in some cases, the
voltage will differ from the original battery. This often
happens when both a Li-Ion battery and a Ni-MH battery are
available for the laptop. |

How
long is the battery life? |
|
|
The life of a
rechargeable battery operating under normal conditions is
generally between 500 to 800 charge-discharge cycles. This
translates into one and a half to three years of battery life
for the average user. As your rechargeable battery begins to
die, you will notice a decline in the run time of the battery.
When your two-hour battery is only supplying you with an hour's
worth of use, it's time for a new battery. |

How long will the new main battery power the laptop? |
|
|
Battery run-time on a laptop is difficult to determine. Actual battery running time depends upon the power demands made by the equipment. The use of the screen, the hard drive, and other accessories results in an additional drain upon the battery, effectively reducing its running time. The total run-time of the battery is also dependent upon the design of the equipment. Generally, a new Hi-Capacity battery will run 30% to 50% longer than the old battery did when is was new. |

I have performed all the steps above but the laptop still will not charge the battery. What next? |
|
|
There is a possibility that either the notebook or the battery is defective. The best way of determining which one is by comparing either the battery or the notebook to a known good one. For example: If the battery does not charge at all, yet another battery charges and discharges properly in the same notebook, then we can assume that the battery is defective. Or: If the battery works fine on one notebook but not the other, then it is the notebook that is defective and will need servicing. |
