Battery and Charge Circuit
On-board Battery
The on-board battery is rated at 3.6 v with a capacity of 650 mAH. The
IBBU 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 IBBU.
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 IBBU 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.
m 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 also illegal.
