BP-1 Battery Pack Installation Guide
You can charge the battery pack while the DAQPad is attached and
operating. If the battery pack is not loaded with a DAQPad in operation, a
full charge is obtained in under 2 hours.
The charge indicator includes a short list of indicator responses and their
meanings.
Powering the DAQPad Series Devices with the BP-1
Battery Pack
Use the following steps to connect the BP-1 battery pack to a DAQPad
device:
1.
Connect the battery pack rear panel plug P1 to the power jack on the
rear panel of a DAQPad device.
2.
Power on the DAQPad device. The power LED on the DAQPad device
should light up immediately.
The power LED does not indicate the charge status of the battery pack.
Therefore, it is important to always start with a fully charged battery pack
and to time the battery usage with the DAQPad device to avoid losing data
and possibly damaging the BP-1 battery pack. The recommended discharge
time for your particular DAQPad device is in your particular DAQPad user
manual.
Taking Care of the BP-1 Battery Pack
Take the following precautions to ensure a long life for your battery pack:
1.
Do not discharge the battery pack for longer than the recommended
discharge time given in your particular DAQPad user manual.
Repeated deep discharge of the battery pack can reduce the life
expectancy of the lead-acid batteries.
Note
As the battery pack ages, the capacity, and therefore, the recommended discharge
time, diminishes.
2.
Recharge the battery pack soon after using it, especially if you deep
discharge your battery pack. Failing to recharge soon after using may
result in extended recharging times.
3.
Recharge the battery pack completely. Repeated incomplete
recharging of the battery pack reduces the capacity of the battery pack.
4.
We recommend that you recharge your battery pack every 18 months
of storage if the battery pack has been stored in a low humidity, 20 °C
atmosphere. For less ideal storage conditions, recharge more often.
