1.3.1
Battery and Charging Process The battery pack is a 10 -cell (1.2V per cell), high capacity nickel metal hydride (NiMH) type, rated at 12 volts and 4 amp-hours (with a minimum of 500 charge cycles). It has a built-in temperature sensor which allows the battery manager to monitor battery temperature.
GENERAL INFORMATION
1.3
BATTERY MANAGEMENT SYSTEM (Continued)
1.3.1
Battery and Charging Process (Continued)
• Float Charge: The float charge phase begins at the end of the top-up phase and helps maintain a fully charged battery. This phase charges at an average rate of 225 mA and 1 second per minute.
• Self-resetting thermal fuse at 70° C.
• Terminates Charge: The power supply processor does not allow charging to begin unless the temperature is 10 - 40° C. The power supply processor terminates charge if battery temperature drops below 10° C or rises above 55° C.
• Self-resetting current limit sense at 5A. The battery charge circuit charges the battery with a constant current of 2A whenever the power supply processor turns the charger on. The power supply processor regulates average charge current by turning the charger on and off with the appropriate duty ratio. The battery charge cycle consists of 4 modes: fast charge, float charge, terminates charge, and top-up charge.
1.3.2
The power supply processor provides the interface between system on/off switch and the main processor. When the instrument is off, the power supply processor interprets either power switch as a turn on command and applies power to the rest of the instrument, informing the main processor the switch was pressed. Once power is on, further presses of a power switch are passed on to the main processor which determines the appropriate response under the existing conditions. If the response is to turn the power off, the main processor requests that the power supply processor remove power from the rest of the instrument.
• Fast Charge: Fast charge is initiated whenever the battery is between 10° C and 27° C, and has been discharged by more than 200 amp-seconds through actual use or self discharge. Leaving the instrument unplugged for a day would cause about 200 amp-seconds of self discharge. The charge current is a continuous 2A. The end of a fast charge is detected when the temperature of the battery is at least 30° C and increases at a rate of 0.7° C/min. (or 1.4A depending on system load at 0.6° C/min.) above its temperature at start of charge, or when the battery voltage declines by 50 mV below its peak value, or total charge time exceeds 2.6 hours. • Top-Up Charge: The top-up charge phase begins at the end of the fast charge phase and finishes adding the last few percent of charge to the battery and balances individual cell charges. This phase charges at an average rate of 0.4A.
System On/Off
If an error has been detected which causes the watchdog to be in alarm, a push of either power switch will immediately cause the power to be turned off, without intervention by the power supply processor. 1.3.3

Use only batteries approved by CareFusion, due to battery manager requirements and the thermostat contained in the battery assembly. If the instrument has been in storage, connect it to AC power before turning it on. One refresh cycle is usually sufficient to restore battery capacity. If necessary, repeat the procedure at 24 -hour intervals, 2 or 3 times, to increase capacity. Several features are included in the battery manager to help properly maintain the battery.
load but will self-discharge from a charged state in about 100 days. This does not damage the battery as it would if it were a lead-acid type battery. Connect the instrument to AC to recharge batteries.
Disposal There are no federal, state or local laws managing the disposal of NiMH batteries. NiMH batteries are recyclable. To learn about recycling batteries at INMETCO, visit their website at http://www.inmetco.com.

BATTERY CAPACITY INFORMATION All batteries have specific conditions under which they are guaranteed to meet their published specifications. Deviations from these conditions typically result in a reduction of available capacity. Manufacturers of NiMH batteries rate capacities, usually expressed in Ah (Ampere-hours), based on a specified "ideal" charge and discharge condition as well as the use of a new battery. An ideal charge cycle starts with a fully discharged battery charged at C/10 (C is rated capacity in Ah) constant current for 15 hours while at room temperature. For example, a 1.8 Ah battery would be charged for 15 hours at 180 mA constant current with a room temperature of 23° C. The ideal discharge starts with a fully charged battery under a C/5 constant current load at room temperature, discharging to a cell voltage of 0.9V. The rated capacity is then calculated as the time to discharge divided by 5. A 1.8 Ah cell would be discharged at 360 mA constant current and not reach 0.9V for at least 5 hours. A given battery type has different capacities based on the load. For example, a battery rated at 1.8 Ah at a 360 mA load may have only 1.6 Ah at a 1600 mA load. There are many conditions which can affect the battery capacity. The following conditions have the most practical impact on battery capacity delivered in this instrument. • Battery Alarm Voltage: The battery alarm voltage is the voltage at which the instrument stops operating and generates an alarm indicating the instrument needs to be connected to AC power. Under perfect conditions, a battery of 10 cells connected in series reaches the end
of discharge at 9.0V; however, cells are not perfectly matched so some will reach 0.9V before others. The problem occurs when a cell in series with other cells can go below 0.9V and actually go into cell reversal, which permanently damages the particular cell. On the other hand, increasing the alarm voltage to compensate for imperfectly matched cells results in reduced run times with available capacity. The user sees this as premature low battery warnings and alarms. The instrument deals with this by increasing the alarm voltage to guarantee the battery is not damaged and reduce the assumed capacity to below that printed on the battery. The battery gauge is intended to show the minimum run time left on the battery taking all these factors into account. • Charge Rate: The ideal charge rate requires 15 hours to get to full charge, which is undesirable from the user’s perspective. The instrument provides a multiphase charge cycle which results in about 80% capacity in the first 2 hours after fast charge. The next charge phase, top-up, is designed to finish the charge and to bring all individual cells to the fully charged state, essentially rematching them. See the "Battery and Charging Process" section in this chapter for "Fast Charge" and "Top-Up Charge" information. If the top-up charge is not completed, the cell mismatch is not reduced and the cumulative capacity reduction occurs. Top-up is a 3 -hour charge but the elapsed time to complete it may be over 5 hours, as the charger is turned on and off to keep the battery cool during that time.

BATTERY CAPACITY INFORMATION (Continued)

The PC Unit’s pole clamp adapts to a wide variety of surfaces, to provide versatility. The pole clamp features include:
• Cycle Life and Aging: Batteries wear out as they get older and go through many charge/discharge cycles; the chemicals and materials used to construct the cell break down. The instrument deals with this by assuming that a battery will continually reduce capacity at a rate equivalent to 30% over 4 years and continually reduce capacity at a rate equivalent to 30% per 200 full charge cycles. These calculated values are used to reduce the run time displayed on the battery gauge. • Partial Discharge/Recharge: When a battery is partially discharged and then charged for less than the full time, differences between individual cell capacities result in cells completing charge at different times. If the full charge sequence is not completed, the cell mismatch becomes progressively greater. This is viewed by the user as low apparent run times and premature low battery warning and alarms. The problem is cumulative in that the mismatch increases for every partial cycle. The lowered capacity is not permanent but may require 2-3 full discharge/charge cycles to recover. The instrument deals with this by reducing the run time displayed based on a limited history of partial cycles. • Temperature During Charge: As the effective ambient temperature of the battery increases, the amount of charge that the battery will accept decreases. At an ambient temperature of 35° C, an enclosed battery will temporarily accept only about 90% of the charge it would otherwise accept at 23° C.
