If you use 50% of a battery's capacity and charge it every time (about 20 to 30 times), then the battery cannot be used at more than 50% of its capacity. This is called the memory effect of battery. If, then, the battery is discharged (made empty) and then recharged, the battery can be used at 100% again.
| -d | Discharges the battery so you can reset the memory effect of battery. |
