| * If your laptop does not allow you to use it when the battery hits a certain percentage (notably HP), you will need to find a workaround to calibrate the battery correctly. This will vary based on the BIOS used (UEFI or Legacy). |
| * In most cases, you will see a battery capacity decrease rather then an increase. This is good, as unaccounted wear is now known. |
| * Once the battery is charging, it is best to let your laptop do it's thing and not use it. This may affect the calibration accuracy. |
