2.6.4.2 

Discharging State 

The battery voltage is drained as part of a relearn cycle. 

2.6.4.3 

Fully-charged State 

Battery voltage level is monitored to determine the level of charge. Charging begins when the 
battery’s sensing logic detects low voltage. 

Once a new battery is fully charged, a relearn cycle is initiated. Relearn is the process of taking 
a fully charged battery through the discharge-charge cycle to update the gas gauge capacity 
parameters. The relearn cycle takes up to 24 hours to fully discharge and recharge the battery 
pack. After the relearn cycle is completed, information from the battery accurately provides the 
state of charge, capacity, and other parameters. 

These parameters determine the health of the battery; a relearn should be performed 
periodically to recalibrate these parameters: 

ƒ 

The relearn cycle can be set at a user-defined interval. The default is one month (30 
days). 

ƒ 

A relearn cycle is initiated when a new battery is inserted, even if the battery was fully 
charged previously. 

ƒ 

Some applications can start a relearn, or a relearn can be manually started. 

2.6.4.4 

Fully-discharged State 

The fully-discharged state is detected as a very low voltage parameter. The charger detects a 
fully-discharged battery state and starts charging the cells when sufficient power is available, 
and when the firmware has completed initializing the pack.
