Battery FAQ



1. How to select the correct battery for my device?

You can find the correct battery based on your device model number and/or battery OEM part number. Read the battery description carefully. The right battery should match our listed battery OEM part number, and compatible device model number. If you are not sure please contact us and we will pick the correct one for you.


2. What is the difference between each type (Ni-Cd, Ni-MH and Li-Ion) of rechargeable battery?

Lithium Ion (Li-ion) batteries do not suffer from the “memory effect”. These batteries have twice the energy of Ni-MH, although they weigh 30% less. This is especially crucial for portable items, such as laptops, digital cameras and camcorders. They are also better for the environment because they don't contain toxic materials such as Cadmium or Mercury.

Nickel Metal Hydride (Ni-MH) batteries last 50%-100% longer than Nickel Cadmium batteries. This battery is generally much more environmentally friendly than Nickel Cadmium.

Nickel Cadmium (Ni-Cd) batteries tend to suffer from “memory effect”. Ni-Cad batteries SHOULD be fully discharged every 3-4 cycles.


3. Can I upgrade my current 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 technology. Refer to your owner's manual to find out which rechargeable battery types your particular device supports.


4. How are batteries rated? (What are volts and amps?)

There are two ratings on every battery: volts and milliamp-hour (mAh). The voltage of the new battery should match the voltage of your original. Minor voltage discrepancy is reasonable and acceptable for replacement batteries.

Some Hi-Capacity batteries will have higher amp-hour ratings than the original battery found in the device. This is indicative of a longer run-time (higher capacity) and will not cause any incompatibilities.


5. How long do batteries last? and when to change the old one?

The life of a rechargeable battery operating under normal conditions is generally between 300 to 500 charge-discharge cycles. This translates into one to three years of battery life for the average user. As the rechargeable battery begins to die, the user will notice a decline in the running time of the battery. When a battery that originally operated the notebook for two hours is only supplying the user with an hour's worth of use, it's time for a new one.

6. What is the length of running time for your new battery? and how to extend battery's life?

The length of battery running time for laptop may change a lot, It depends on the running applications and the external devices connected to your laptop. Battery running time will decrease over time. When you have a trip with your laptop, you would like to have a longer battery life. Here are some suggestions may help you save battery's power.

1. Adjust your screen brightness to the lower level.
2. Shut down unnecessary programs.
3. Remove unnecessary devices.
