Battery Information |

All available information about each available battery is displayed in this window. How accurate this information is depends on the device driver software supplied with the battery pack and the intelligence of the battery pack. Smart battery packs can provide detailed information about the battery, while dumb battery packs may supply nothing at all. If no information is available the letters N/A are displayed. Battery systems have slots and batteries. A slot is a socket that can hold a battery pack. It’s not unusual to have more slots that batteries.

Status: Indicates the current status of this particular battery. Values include, “Charging”, “Discharging”, “Critical” and “Not in use”. The Critical status indicates imminent failure.

Manufacturer: The name of the company that manufacturers the battery pack.

Device Name: The name of the device. This is often the model number of the battery pack, as defined by the manufacturer.

Serial number: The serial number of the device as defined by the manufacturer.

Unique ID: An identification string, which is unique across all battery packs. This is often a concatenation of the serial number, the device name and the manufacturers name.

Time remaining: A rough estimate of how much time remains before the battery is fully discharged.

Battery Temperature: The temperature inside the battery pack.

Date of manufacture: The date when the battery was manufactured.

Type of use: Indicates if the batteries normal use is to provide power for normal operations or if the battery is a fail safe device.

Rechargeable: Indicates if the battery is rechargeable or not.

Chemistry: The type of battery. Typical values are, Lead Acid, Lithium Ion, Nickel Cadmium, Nickel Metal Hydride, Nickel Zinc, Rechargeable Alkaline-Manganese

Design capacity: The theoretical capacity of the battery when new. For most batteries this is measured in milliwatts hours.(mWh). For some batteries this figure may not have any units, and will be a relative value.

Full charge capacity: The battery's current fully charged capacity in mWh (or relative). In some batteries it is possible to compare this value to the designed capacity to estimate the battery's wear.

Current capacity: The battery’s current charged capacity in mWh (or relative). For some batteries this figure may not have any units, and will be a relative value.

Alert levels: The manufacturer's suggestion of when a "low" and “Warning” battery alert should occur. Definitions of "low" and “Warning” will vary from manufacturer to manufacturer.

Bias: Some batteries reserve a small charge that is biased out of the battery's Full Charge Capacity and Current Capacity values to show "0" as the critical battery level. Critical bias is analogous to setting a fuel gauge to show "empty" when there are several liters of fuel left.

Charge cycles: The count of the number of charge/discharge cycles the battery has experienced. This provides a means to determine the battery's wear. Not all batteries will support this feature.

Voltage: The current battery voltage in Volts across the battery terminals.

Charge Rate: The current rate of battery charge or discharge. This value will be in mW unless the battery is relative, in which case it will be in arbitrary units per hour. A nonzero positive rate indicates charging; a negative rate indicates discharging.
