Extended Storage
Do not store the
SurePower II Battery Pack
for extended periods in a fully charged state. If you
must store the battery pack for an extended period
1. Charge the
SurePower II Battery Pack
until three runtime LEDs light (this takes
approximately 1.5 hours when charging a fully depleted battery).
2.
Recharge the
SurePower II Battery Pack
until three runtime LEDs light every 4 months.
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.
After displaying battery capacity for 2 seconds,
all LEDs blink and then display the battery’s
runtime.
Over time, as you use a SurePower II 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.
