Martel Electronics BP-33 User Manual

Beta 330 rechargeable battery set includes:

• 8 cell Ni-MH Battery pack

• Cell-Con smart battery charger

• Beta330 Battery Patch Cord

Charging the Battery:

Charging begins when a battery pack is connected to the charger. The LED will
be orange before the fast charge starts and the LED changes to red. When the
cells are fully charged and the voltage drops (because of the -dV signal from
the cells), the charger will go into a top-off charge mode before switching to
trickle charge mode.

During the top-off charge session, the LED will be green with short, intermittent
orange flashes. When the top-off charge is complete, the charger will go into
trickle charge mode, changing the LED color to green. The charge current is
now reduced to a safe level, permitting the charger to stay connected to the
battery pack without damaging the cells.

If the safety timer disconnects before -dV, the top-off charge will not be
engaged. The charger will then go directly to trickle charge mode and the LED
will be green in color. If the battery voltage is far below normal, the charger will
stop the fast charge current and switch to trickle charge mode. The LED will
then indicate "error" by flickering green and red.

If the mains are turned off, the charger will reset and start a new charge cycle if
the mains are turned on again.

Installing Rechargeable Battery:

1. Open the Battery cover and disconnect the regular battery pack from 330.

2. Connect the patch cord to the unit. See Figure 1

Note: Do not connect the Patch Cord to the battery. Connect it to the unit
first.

3. Connect the battery pack to the patch cord as it shown on the Figure 2.

Note: Take a close look at the connector keys. Red wires will be crossed
with black.

4. Locate the battery pack in the unit battery compartment as is shown on
Figure 3.

5. Now you can close the battery door and use the unit.

Using Rechargeable Battery:

Rechargeable Battery has a 2.7Ah rating and can perform better with the pump
running compared to regular Alkaline Batteries which are about 2.0Ah.

But the Rechargeable Battery has high self discharge rate so batteries that
have not been used in 30 days or more may need to be charged before use.
