2.2.7. System Power
2.2.7.1. Battery Operation
The 3880 system utilizes Lithium Polymer ‘smart’ battery technology with self-monitoring. When
all components of the system are turned on and communicating, the battery charge status is
displayed on the 3880 Monitor and 3885-T Remote Tablet displays. The actual battery capacity
will decrease over time and a full battery symbol may not indicate the same capacity and
operating time as compared to a new battery.
The system’s batteries each contain lithium-polymer cells and integral safety circuits. As these
cells age, they can expand due to internal gas release, which is anticipated for this type of cell.
However, if excessive expansion occurs, this can result in the battery case expanding
(swelling), and possibly cause failure of the battery case, cells, or safety circuit. If this is
observed, remove the Battery Pack or PODs from use and replace it as soon as possible.
! WARNING
• Avoid damage to the Battery Pack by impact, dropping, overheating, or mechanical
abuse. Never compress, drop, shock, or strike the Battery Pack. Never use objects that
could puncture the internal battery cells. Any of these actions can cause the battery cells
to heat, smoke, or cause catastrophic battery failure, which could result in fire.
• Do not attempt to disassemble the Battery Pack. Damage caused by disassembly or
tool use can result in catastrophic battery failure, which could result in fire.
• Under no circumstances should Battery Packs or the internal cells be incinerated as this
can cause an explosion.
• If PODs or batteries are dropped, perform a physical and functional inspection before
returning them to clinical use.
! CAUTION
• The battery packs may contain slight magnetic properties. Use caution when removing
or inserting the batteries near strong magnetic fields (30,000 Gauss).
• If the 1133 Battery Pack case begins to expand and/or swell, discontinue battery
charging and use immediately, and replace the battery pack. Continued charging will
cause further battery pack case expansion, with possible battery case fracture, and
potential electrolyte leakage.
• Only operate the monitor with the battery pack installed.
• Immediately charge a device that has a low battery.
NOTE
• The operating time depends on the configuration and operation of the 3880 system. For
example, measuring NIBP more frequently will shorten the operating time.
• Review the Battery Maintenance in Section 8 of this manual prior to initial use.
• The 3880 monitor utilizes a user replaceable battery pack which enables continuous
monitoring. The Wireless PODs and 3885-T Remote Tablet feature integrated batteries
so backup devices maybe necessary for continuous monitoring longer than 10 hours.
• If the system is power cycled during a case always confirm settings and patient name
prior to resuming monitoring activities.
