Extended Storage
Do not store the SurePower Battery Pack for extended periods in a fully charged state. If you
must store the SurePower Battery Pack for an extended period:
1. Charge the SurePower Battery Pack until three runtime LEDs light (this takes
approximately 1 hour when charging a depleted battery).
2. Every 4 months, recharge the SurePower Battery Pack until three runtime LEDs light.
Checking Capacity Loss
To check battery capacity (the amount of charge the battery can hold), press and hold down the
Display button for at least 5 seconds.
Press and hold down the Display button for at least
5 seconds.
While you hold down the
Display
button, the
runtime indicator displays the battery runtime.
When you release the
Display
button, the
runtime indicator displays the battery capacity
for 2 seconds, then redisplays the battery
runtime.
During the 2 seconds after you release the
Display button, the runtime indicator displays
battery capacity and will light five LEDs to
indicate that the capacity is equal or close to
that of a new battery.
Over time, as you use a SurePower Battery
Pack
, the battery capacity decreases and this
capacity check will light fewer LEDs. When the
capacity check lights only a single LED, the
battery is at or near 60% of its original capacity,
and you should remove the battery from service.
If the Recalibration or Fault LED lights after
you release the Display button, the runtime
indicator will not display the capacity or run time
for that battery.
