Motorola Mc9500k Manual

							Chapter 2 Battery Management
Introduction
This chapter provides information on battery functionality, battery status indications, charging the MC9500-K, 
charging spare batteries and power saving techniques.
Battery Functionality
The 4800 mAh battery provides power to the MC9500-K and contains charging and status indications on the front 
of the battery. The indicators function differently depending upon the battery mode and allow the user to determine 
the health of the battery.
Figure 2-1    Battery
Charging Status LED indicates the charging status and health of the battery. The Charge Level Indicator indicates 
an unhealthy battery and the charge level of the battery.

Battery Health
A battery becomes unhealthy when the Battery Usage Indication reach a predefined threshold (end of usable 
life).
The Battery Usage Threshold value can be changed. See the MC9500-K Mobile Computer Integrator Guide for 
more information.
When the battery becomes unhealthy, a dialog box displays on the MC9500-K. When this appears, tap Dismiss. 
Replace the battery as soon as possible. The battery Charge Level indicator display an “X” when the battery 
becomes unhealthy (see Figure 2-3). When charging an unhealthy battery in the MC9500-K, the Battery Status 
LED blinks red.

Battery Status
The MC9500-K battery provides status information on the front of the battery that allows the user to make 
determination on what battery to use. The battery status indications vary depending upon the mode of the battery:
Installed in an MC9500-K
In a charger
stand-alone.
Installed in an MC9500-K
When the 4800 mAh battery is installed in the MC9500-K, the user can view the charge level (with Status button 
press) and health of the battery (see Figure 2-4). The Battery Status LED is disabled when the battery is installed in 
the MC9500-K. If the battery is unhealthy, the Charge Level indicator displays an “X” (see Figure 2-3).

Press the Status button to display the current battery charge level. It will display for five seconds and then turn off. 
Table 2-1 list the Charge Level indications when the Status button is pressed.
NOTEThe Charge Level indicator does not display the charge level while the MC9500-K is charging.

In a Charger
When the battery is in a Single Slot Battery Charger, Four Slot Battery Charger or Vehicle Battery Charger, the 
battery charging status and health is indicated on the front of the battery. If the charger is not powered, the battery 
acts as if it is in stand-alone mode. See Stand-alone on page 2-8 for more information.

When the battery is not installed in an MC9500-K or a charger, the charge status and health of the battery displays 
on the battery front panel. If the battery is unhealthy, an “X” appears in the Charge Level indicator. Press the Status 
button to view the health and charge level of the battery. The Battery Status LED lights and the Charge Level 
indicator display the charge level. After five seconds the LED turns off and the Charge Level indicator reverts to the

Charging the MC9500-K
The MC9500-K is equipped with a memory backup battery which automatically charges from the fully-charged 
main battery. When using the MC9500-K for the first time, the backup battery requires approximately 36 hours to 
fully charge. This is also true any time the backup battery is discharged, which occurs when the main battery is 
removed for several hours. The backup battery retains RAM data in memory for at least 15 minutes (at room 
temperature) when the MC9500-Ks main battery is removed. When the MC9500-K reaches a very low battery 
state, the combination of main battery and backup battery retains RAM data in memory for at least 36 hours.
To charge the battery, use either a cradle or charging cable. For cable and cradle setup and charging procedures 
refer to the MC9500-K Mobile Computer Integrator Guide. 
To charge the battery:
1.Connect the charging accessory to the appropriate power source. See MC9500-K Series Mobile Computer 
Integrator Guide for setup information.
2.Align and hook the MC9500-K interface pocket onto the cradle’s or cable’s cleat. The MC9500-K begins 
charging. The Charging/Battery Status LED blinks while charging, then turns solid when fully charged (LED 
color depends upon health of the battery). See Table 2-6 for charging indications. The 4800 mAh battery fully 
charges in less than six hours.
CAUTIONEnsure that you follow the guidelines for battery safety described in Battery Safety Guidelines on page 9-2.
