Keep the IBM Laptop Battery 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 Pack - 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. Ni-Cd, Ni-MH and Li-ion batteries will self-discharge during storage; remember to recharge the batteries before use.

What is the run time of IBM ThinkPad 380ED Laptop Battery?

IBM Laptop Battery have two main ratings on them: Volts and Amperes. Because size and weight of Laptop Battery is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Mill amperes. One thousand Mill amperes equals 1 Ampere. When buying a battery, select batteries with the most Mill amperes (or Ah). 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 Laptop Battery can power 57.60 watts for one hour. If your laptop, power tools, camcorder, camera, pda, or mobile phone runs at 20.50 watts, as an example, this battery could power your laptop, power tools, camcorder, camera, pda, or mobile phone for 2.8 hours.

4. Separate power reset the device with the move to remove the battery. Then the power button for a minute. Then put the battery and AC adapter and restart the laptop. This method is to ensure that the motherboard is not more power they have, when the battery was reduced easily cause a hiccup in the system. That might solve the battery.
5. If the battery level indicator in each load reaches 96-98% complete, the laptop should be recalibrated for a new battery. An appropriate recalibration, the laptop should be configured to the Windows power management will be in hibernation or standby to ensure that, when the battery reaches a low level. For users of Windows XP, go to Control Panel Performance and Maintenance Power Options. Power Schemes to Always On Set. In the Notifications, disable Low battery alarm and Critical battery alarm. The hibernation option Sleep, and click Apply. This process can be a notebook battery is completely closed by the system to be drained. After restarting the network adapter in the slot and is left completely free. Sometimes the cycle is repeated 2-3 times before reaching 100% in fact fully charged.
