Battery and Charge Circuit

Onboard Battery
The onboard battery is rated at 3.6 v with a capacity of 650 mAH. The BBU
has a DC-DC converter that converts the 3.6 v from the battery to 5 v, which
is the nominal voltage needed to replace V

CC

if a power failure should occur.

Battery Charger
Battery charging and conditioning are automatically handled by the BBU.
No manual preconditioning needs to be performed by the user. If the battery
capacity falls below a predetermined level (which is likely to happen during
a power failure), the battery charger goes into a quick charge mode. If the
battery is fully charged, the charger goes into a trickle charge mode.

Recycling the Battery

The on-board battery that comes with the BBU has the logo of the
Rechargeable Battery Recycling Corporation (RBRC) stamped on it. The
logo means that recycling fees have been prepaid on this battery pack.

Caution

Do not dispose of a rechargeable battery with regular
trash in a landfill. Rechargeable batteries contain
toxic chemicals and metals that are harmful to the
environment. Improperly disposing of rechargeable
batteries is illegal.

The RBRC is a non-profit corporation that promotes the recycling of
rechargeable batteries, including nickel-cadmium batteries.

Information on the RBRC program and the locations of participating
recycling centers can be obtained by telephoning 1–800–8–BATTERY (in
the U.S.A.), and following the recorded instructions. The information
obtained from this telephone number is updated frequently, since the RBRC
program is growing, and new recycling locations are being added regularly.
