Battery Capacity Check
Several variables affect monitor operating time on battery:
• active options
• frequency of NIBP measurements
• frequency and length of printouts
• ambient temperature,
• battery age and condition
• displayed information.
Refer to the Propaq Encore Reference Guide for battery care information and expected
operating times. If the monitor fails to operate on battery for an extended period of time,
follow the procedure below to check the capacity of the Encore’s lead acid battery. Lead
acid batteries have a very limited shelf life; you must test the battery if the Encore has
been stored for two or more months without the ac power adapter plugged in.
1. Use the ac power adapter and charge the monitor for at least 8 hours with the
monitor turned off (12 hours if a printer or pulse oximeter is attached).
2. Disconnect the cuff and all cables from the monitor.
3. Turn off all printing (if a printer is attached).
4. Disconnect the power adapter.
5. Turn on the monitor.
6. Run the monitor for 4 hours.
7. Check that the monitor did not automatically turn off.
8. Press MAIN MENU.
9. Use the ac power adapter and charge the monitor for at least 8 hours with the
monitor turned off. (Charge at least 12 hours if a printer or pulse oximeter is attached.)

Caution A new battery should pass the following test. The run time of older
batteries will decrease proportionally with age. Replacement is recommended
when the run time becomes insufficient for the monitor's intended application.
