Afterhundreds of charge and discharge cycles, batteries lose some charge capacity, or battery health. Tocheck the battery health, press and hold the status button on the battery charge gauge for at least3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of itsoriginal charge capacity remains. Each light represents incremental degradation. If five lightsappear, less than 60 percent of the charge capacity remains, and you should consider replacing thebattery.
