Circuit cut-off voltage (pack voltage)
Preset data is indicative. Capacity, voltage cutoffs and self-discharge vary by manufacturer, model, temperature, load and age. Check the exact cell datasheet and edit the values above. Series increases voltage; parallel increases capacity. Circuit cut-off values are pack-level voltages. The effective-capacity estimate uses the overlap of the battery voltage range and the usable input range for the selected conditioning type.
Pack capacity3,000 mAh
Effective capacity2,550 mAh
Pack voltage range2.50–4.20 V
Power conditioning
Effective capacity is estimated from pack capacity, voltage limits and usable-capacity allowance.
For a continuously powered display, active and idle durations are treated as a repeating active/idle pattern. For a periodic display, enter the total time the display is active each time it turns on.
