iCad, NiMH and Li-Ion Excel notebook batteries are all fundamentally different from one another and cannot be substituted unless the notebook notebook 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 notebook device supports or use our Excel Battery Finder above to find all the compatible notebook 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 notebook uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new li-ion notebook battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the li-ion battery.


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.
