Elsewhere I read that it helps to let the computer calibrate the new battery, using these steps:
- Fully charge the battery.
- Remove the power cord, allowing the battery to run the computer.
- Ensure that the screen stays lit (turn off screen savers and screen blanking).
- Leave the computer on, until the battery dies.
The computer apparently records the power levels and times to create a accurate profile of the battery's characteristics.
Battery Charging Time
The drawback to high-capacity batteries is that they take a long time to charge, especially while the computer is on.
With the LG X110 netbook, the 9-cell battery took 3hr 10min to charge to 90% of capacity. That's where the netbook's green-colored charge light changes from steady to flashing. It took another hour to get to 100%.
With the battery fully charged, I tested how long it could run the computer. (I had brightness on full, WiFi off, and nothing else happening.) To test the accuracy of the battery meter, I recorded the Time Remaining and Percent Full every 30 minutes, as reported by Windows 7.
