Battery Management
The following techniques and practices help ensure
proper battery performance to prolong the life of your
battery.

It is recommended that the BPM200/BPM300 turned
off and left plugged in when not in use to ensure
maximum battery life.

Operate the BpTRU with the power supply plugged
into a wall outlet whenever possible.

Charge the battery overnight if the BpTRU was used
in battery mode for more than two hours, or if the
low-battery indicator is displayed (
).

Charge and then disconnect the battery if the BpTRU
is to be shipped or stored for longer than one month.
The low-battery indicator lights when the BpTRU needs
charging. It will also emit a short double beep every 30
seconds when the battery is low. When these indications
occur, plug the power cord into a wall outlet to charge
the battery. Note that it is possible to perform
measurements while the battery is charging.
If the battery charging indicator remains on for longer
than 24 hours during charging, the battery needs to be
replaced.
It is recommended that the battery be replaced every 2
years. Refer to “Replacing the Battery” on page 49 for
replacement instructions.
CAUTION
Using batteries beyond their recommended lifetime
may result in damage to the BpTRU.
