How to Maximize and Battery Performance?
It is recommended to condition(fully charge and discharge) the new battery few times to allow it to reach its maximum rated capacity. Condition the NiMH and Nicd battery at least once a month.It will reduce the memory effect. Use the battery at least once a month even it was kept in a dry and cool storage. Clean the metal connector(the contact to the notebook,usually in color of gold or silver)by alcohol or Electronics Cleaner Degreaser.It will maintain the good conductivity. which improves the power conduction from battery to Notebook. Fully optimize the Power Management features the provides in system BIOS and Operating System will also improve the battery performance. Consult the user's manual to fully understand the usage of these features.

Can I use my older NiCD battery charger to charge my NiMH batteries?
No, you can use a newer NiMH charger to charge your old NiCD batteries but you should not try to charge NiMH batteries with a NiCD charger. Here's why: NiMH and NiCD batteries are chemically very similar and when both are fully charged the battery voltage will start to drop. The NiMH voltage drop is much more subtle and more difficult to detect. NiMH chargers usually have an over temperature sensor and shutoff to prevent overcharge as well as a more sensitive voltage drop detector where NiCD chargers usually only use the voltage drop to determine when to stop charging. If you charge NiMH batteries in a NiCD charger it will probably miss the voltage drop and keep right on charging causing the batteries to overheat. Overcharge and overheating NiMH batteries can damage them internally and reduce battery life.

What if the computer does not operate with a fully charged battery pack?
The over-current protective function in the battery pack might be activated. Power off the computer for 1 minute to reset this function; then power it on again.

My new battery isn't charging. Is it defective?
Usually NO. New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity. It is generally recommend an overnight charge (approximately twelve hours). It is normal for a battery to become warm to the touch during charging and discharging. When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. New batteries are hard for the device to charge; they have never been fully charged and not broken in.?Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

Can I upgrade my device's battery to a newer chemistry?
Ni-Cd, 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. Therefore, the portable device's charger must be properly configured to handle a given type of rechargeable battery.

Please refer to your owner's manual to find out which rechargeable battery types your particular device supports, or simply use our search engine to find your device. It will automatically list all of the battery types particular device supports.

How are batteries rated?
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 than the original battery found in your device. This is indicative of a longer run-time (higher 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.
