Battery Handling, Maintenance and Good Practices
This section provides some information on how to handle and maintain the battery in order to
get the best usage from it. Additionally, some good working practices are also given
regarding the correct disposal of the battery.

The rechargeable battery used in the Monitor is regarded as a 6PDUW battery because it has
built-in circuitry. (This circuitry communicates battery-status information to the Monitor.)
When you receive a new battery, this circuitry is dormant (sleeping) and needs to be
activated.
Initialize a new battery by pressing on the button below the charge LEDs until the LEDs
light. Once this happens, the battery needs to be put into use otherwise it will deteriorate.

If an unused battery cannot be initialized (the LEDs do not light), a MALFUNCTION
message will appear when it is inserted imn a monitor.In theis situation it means that the
smart battery is really empty and canot communicate. The battery is normally in order and
the message disppears after 5 to 10 minutes of charging.
To get the most out of a battery, observe the following guidelines:
• The shelf-life of an unused and unopened (sleeping) battery is about 6 months.
• Once the battery has been activated, it should be put into use. If it is left to discharge, its
useful life will be dramatically reduced.
• Condition the battery approximately every 50 recharge cycles.

• Charging rate of the battery:
Monitor Off: 1.4 Amps.
Monitor On: 200 mAmps max. (Depends on how the Monitor is loaded).
• %DWWHU\'LVSRVDO—Batteries should be disposed of in an environmentally-responsible
manner. Consult the hospital administrator or your local Agilent Technologies representa-
tive for local arrangements.

When the Monitor is connected to the mains power supply, the battery charges automatically.
The battery can be charged remotely from the Monitor by using the battery charger (order
number M3080A Option #C32).
Battery status (level of charge) is indicated several ways:
• LEDs on the front panel of the Monitor.
• Battery gauge.
• Battery status menu.
