Portable Battery Pack Charge Status Indicators The charge state of the battery pack is monitored and stored within registers internal to the battery pack electronics. This may be referred to as a fuel gauge. The charge status LEDs on the battery pack indicate the remaining charge in the following manner: - 81% - 100% charge capacity remaining - 61% - 80% charge capacity remaining - 41% - 60% charge capacity remaining - 21% - 40% charge capacity remaining - 5% - 20% charge capacity remaining - 0% - 4% charge capacity remaining - The battery pack has failed or is damaged. For more torough failure description, refer to third step in this document: System Battery/Charge LED. Battery degradation status indication. Portable system batteries as with all other rechargeable batteries degrade over time. The amount of time the battery will operate the device on a full charge will reduce as the battery ages. This performance loss is also based on the number of times the battery is discharged and charged.

Dell portable system batteries provide a way to monitor the degradation. The degradation status will display after holding the battery check button, located on the battery pack, down for more than 3 seconds. The battery pack LEDs will then show overall battery degradation after the charge gauge reports the battery's current charge capacity. The degradation LEDs display the following: - 100% – 80% charge performance is remaining - 79 – 75% charge performance is remaining - 74 – 70% charge performance is remaining - 69 – 65% charge performance is remaining - 64 – 60% charge performance is remaining - 59% or less charge performance is remaining The hinge or system battery LED can indicate many battery states. The LED can blink and change color representing the battery's current operational condition.
