FUJITSU-SIEMENS Laptop Battery Articles & Tips
Upgrade my FUJITSU-SIEMENS Laptop Battery from NiMH to Li-Ion
NiCad, NiMH and Li-Ion FUJITSU-SIEMENS laptop batteries are all fundamentally different from one another and cannot be substituted unless the laptop has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our FUJITSU-SIEMENS Battery Finder above to find all the compatible laptop batteries for your device. It will automatically list all of the battery chemistries supported by your specific device. If your device does allow you to upgrade the battery from NiMH to Li-Ion, you will typically get longer run times.
For example, if your laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the li-ion battery.
Example.
Li-Ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-Ion is stronger and has longer run time.

How can I maximize the performance of my FUJITSU-SIEMENS laptop battery?
There are several steps you can take to help you get maximum performance from your laptop battery:
Prevent the Memory Effect - Keep the laptop battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect.
Keep the FUJITSU-SIEMENS laptop 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 the portable device.
Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a laptop battery has not been used for a long period of time, perform the new battery break in procedure described above.
Battery Storage - If you don't plan on using the laptop battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to recharge the batteries before use.
What is the run time of Replacement-laptop-battery.com's laptop battery?
FUJITSU-SIEMENS laptop batteries have two main ratings on them: Volts and Amperes. Because size and weight of laptop batteries is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, select batteries with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. For example:
14.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes).
14.4 x 4.0 = 57.60 Watt-Hours
Watt-Hours signifies the energy needed to power one watt for one hour. This FUJITSU-SIEMENS laptop battery can power 57.60 watts for one hour. If your laptop runs at 20.50 watts, as an example, this laptop battery could power your laptop for 2.8 hours.
Understanding your FUJITSU-SIEMENS Battery Needs
We strive to make you laptop battery purchases easy. Since we understand that finding the right batteries for your needs can be overwhelming and confusing at times we developed a laptop battery finder tool to help find the right size for the make and model of your equipment. We also offer educational articles and tips to help you conserve your batteries and understand common problems. By us providing education you are able to make the right purchasing decisions as well as provide proper care for all of your electronics.
