Batteries
Two rechargeable battery packs are located in slots 23 and 28 behind the battery
retainer.
The batteries installed in all system enclosures are identical.
A battery pack contains:
24 sealed, cylindrical, lead-acid cells
A nonreplaceable fuse for short-circuit protection
These batteries automatically power the system when AC power fails. In addition to
powering the memory for as long as they can, usually 45 minutes, the batteries can
continue to operate all the components in a system enclosure for a configurable length
of time.
Recharging Batteries
Batteries are continuously charged when AC power is applied to a system enclosure.
Spare batteries require recharging at least every six months. To recharge your spare
batteries, you can swap them with the batteries currently installed in your system every
three or four months. Batteries are FRUS and must be replaced by an authorized
service provider.
Batteries are designed to handle occasional power failures that occur at most
computer sites. Frequent power failures (averaging more than once a week) can cause
the batteries to wear out more quickly.
Disposing of Batteries
Many countries and local governments have special ordinances that must be followed
when disposing of spent lead-acid batteries. United States federal, state, and local
laws govern the management, recycling, and disposal of lead-acid batteries.
