Battery life
The batteries have a lifespan of three years and hold a charge for a specic amount time
when disconnected. When the batteries ar
e connected and po
wer is on, the batteries ar
e
continuously char
ging. The process occurs during both normal system operation and
while the system is in idle mode.
When the batteries are connected and the power is o, the batteries slowly discharge its
power. The batteries have a charge of less than 50% after two weeks without power.
When the batteries are fully discharged, the batteries must be connected to power for
three hours to fully recharge.

age system gener
ates a SIM when the cache backup batteries
ar
e not char
ged to at least 50%. The LEDs on the front panel of the cache
backup kits also show the status of the batteries.
Storing the system
While connected, the cache backup batteries completely dischar
ge in two to thr
ee weeks
without po
wer. If you ar
e not using the storage system for two weeks or more, contact
customer support to move the batteries to an active storage system, or set the storage
system to idle mode for at least 3 hours once every two weeks.
If you store the system for more than two weeks without disconnecting the cache
backup batteries, the batteries need to charge for at least 90 minutes when you restart
the system before the cache can be protected. To prevent the batteries from discharging
during long-term storage, contact technical support and request a disconnection of the
