Changing the Battery Backup Unit
The optional MegaRAC G2 Battery Backup Unit must be replaced
every 400 cycles. Cells retain 80% of their original capacity after 400
cycles. A cycle is defined as a full charge (4.2V) followed by a full
discharge (2.8V). Keep in mind that cycling or storing the cells at
elevated temperatures can reduce the cell capacity and cycle life.
Cells discharged and stored at low temperatures can extend the shelf
life of the batteries.

Step Action
1 Bring down the operating system properly. Turn the
computer power off. Remove the computer cover. Remove
the MegaRAC G2 card.
2 Disconnect the battery pack cable from the J1 jumper on the
MegaRAC G2 card. Remove the plastic battery clip and
then replace the Battery Backup Unit.
3 Install a new battery pack and connect the new battery pack
to the J1 jumper.
4 Reinstall the MegaRAC G2 card into the host system.
Note: Li-Ion has no memory effect. Lithium-ion cells offer
extended cycle life when cycled at low depth of discharge.
Storage
If you keep a stock of extra MegaRAC G2 batteries, store them at
room temperature.
Note: The recoverable capacity of cells stored for over one year at
room temperature and fully charged is 94%. The retained capacity of
these same cells is 87%. This means the self-discharge rate for a fully
charged cell is approximately 150 mAh per year or 427 uAh per day.
The self-discharge rate for cells is non-linear. A partially charged cell
has a self-discharge rate of about 80 uAh per day.
Disposing of a Battery Pack Battery Disposal Laws
WARNING!
Do not dispose of the MegaRAC G2 Battery Backup Unit by
fire. Do not mutilate the battery pack. Do not damage it in any
way. Toxic chemicals can be released if it is damaged. Do not
short-circuit the battery pack.
IMPORTANT!
Most used Lithium-ion batteries are not classified as
hazardous waste under the federal RCRA (Resource
Conservation and Recovery Act). Although Minnesota law
requires that Lithium-ion batteries be labeled “easily
removable” from consumer products, and that Lithium-ion
batteries must be collected by manufacturers, the
Minnesota Pollution Control Agency (MPCA) has granted
a temporary exemption from these requirements.
The material in the battery pack contains heavy metals that can
contaminate the environment. Federal, state, and local laws prohibit
disposal of some rechargeable batteries in public landfills. These
batteries must be sent to a specific location for proper disposal. Call
the Rechargeable Battery Recycling Corporation at 678-419-9990
(FAX: [phone]) for an authorized battery disposal site near you.
