We strive to make you laptop battery purchases easy. If your laptop runs at 20.50 watts, as an example, this laptop battery could power your laptop for 2.8 hours. This COMPAL laptop battery can power 57.60 watts for one hour. Watt-Hours signifies the energy needed to power one watt for one hour. For example:ġ4.4 Volts, 4000mAh (Note: 4000mAh is equal to 4.0 Amperes). This is found by multiplying the Volts and the Amperes together. Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. When buying a battery, select batteries with the most Milliamperes (or mAh). One thousand Milliamperes equals 1 Ampere. 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. What is the run time of 's laptop battery?ĬOMPAL laptop batteries have two main ratings on them: Volts and Amperes. NiCad, NiMH and Li-Ion batteries will self-discharge during storage remember to recharge the batteries before use. If a laptop battery has not been used for a long period of time, perform the new battery break in procedure described above.īattery 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.

#Compal hl90 battery upgrade#
If your device does allow you to upgrade the battery from NiMH to Li-Ion, you will typically get longer run times.įor 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. It will automatically list all of the battery chemistries supported by your specific device.
#Compal hl90 battery manual#
Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our COMPAL Battery Finder above to find all the compatible laptop batteries for your device. NiCad, NiMH and Li-Ion COMPAL 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.
