WARNING: Danger of explosion if incorrect battery replaced. Operate only with AA batteries.
Please follow your regional recycling scheme for batteries, packaging, and electronic waste.
The Shure Battery Rack Charger (SBRC) supports up to eight rechargeable batteries in a compact, single rack space. SBRC accepts interchangeable charging modules that accommodate Shure Lithium-ion batteries including AXT910, AXT920, and SB900B. An easy-to-read front panel displays essential battery parameters including charge status, time-to-full, and battery health indicators (such as temperature and cycle count). When connected to a network, Shure Wireless Workbench® software provides remote monitoring of the SBRC to track battery status.

| LED Color | Charging Mode | Display | Battery Status |
|---|---|---|---|
| Green | Charging Complete | Home Screen | Battery charged |
| Red | Charging | Home Screen | Battery charging |
| Deep Discharge Recovery | Home Screen | Battery charging | |
| Charging | Warm | Battery charging, temperature warm | |
| Red Flashing | Storage Mode | Store at 3.8V | Battery charging or discharging to 3.8 volts |
| Amber | Storage Mode | Store at 3.8V | Battery voltage at 3.8 volts |
| Amber Flashing | Charging | Error - press SET for info | Charging error, press SET button for information |
| Deep Discharge Recovery | Error - press SET for info | Deep Discharge Recovery failed | |
| Charging | Warm | Battery charged to 80 percent | |
| Charging | Hot | Charging stopped, battery hot | |
| Charging | Cold | Charging stopped, battery cold |
Press and hold both arrow buttons to enter or exit the Utility menu.
Press and hold the SET button for 1 second to activate the Hardware Identify feature in Wireless Workbench.
Slide the battery into the charging bay until it locks into place. The charge LED illuminates and the charge cycle begins.
When powered on, the charger displays the home screen. Icons indicate the charge level of each battery, and the display alternates to show approximate hours and minutes remaining until the battery is fully charged.
The numbers on the screen correspond to the charging bays 1 through 8 from left to right.
The following messages may be displayed next to the bay number to indicate battery status:
| CALC | calculating time to full |
| COLD | battery cold |
| WARM | battery warm |
| HOT | battery hot |
| Recovery | recovery mode active |
| Error | error - press SET button for information |
Use the monitoring menu to access detailed information about each battery.
Displays the time remaining until the battery is fully charged.
IMPORTANT: Battery might not be charged to full capacity if any of the following status indicators appear:
Displays charge as a percentage of the total battery capacity. Also displays charge in milliampere-hours (mAh).
This displays the health of a selected battery as a percentage of the charge capacity of a new battery. Charge capacity (battery life when fully charged) will decline as a result of repeated charge cycles, age, or storage conditions.
Displays the total number of times that the battery has undergone one full count of discharge and charge. Recharging after discharging half way counts as one half of a cycle. Recharging after discharging a quarter of the way counts as one quarter of a cycle.
Displays both the battery temperature (in Celsius and Fahrenheit) and the status, as follows:
Note: If warm or hot, try adjusting the fan speed or increasing ventilation to the rack.
IP address must be valid to enable networked control.
Press and hold both arrow buttons to enter and exit the utility menu, which contains network and display settings.
This is the default setting for use with a DHCP server, which automatically assigns an IP address.
Use manual IP addressing to manually set the IP address, subnet mask, or gateway.
Entering an IP Address
Displays current gateway (GW) address. Press SET button to edit in IP menu.
Setting the Gateway
Displays the current subnet setting. Press SET button to edit in IP menu.
Setting the Subnet
Displays the MAC address, which is an embedded, uneditable identification number unique to each device. The MAC address is used by the network and Wireless Workbench software to identify components.
Sets the brightness of the display to low, medium, or high.
This changes the display colors from white text on dark background to dark text on a light background.
The cooling fan has the following speed options:
Note: Speed may switch from Low to High if additional cooling is needed to protect the component.
The cooling fan has the following operating modes:
Displays the version of firmware installed on this device.
Displays the serial number.
This eight-character name is displayed when this device is detected on other network devices or in WWB software.
When set to storage mode (Storage Mode = Store at 3.8 V), all batteries are charged or discharged to 3.8 volts, which is ideal for long-term storage.
The charge status LEDs indicate the voltage state:
The following indicators appear on the home screen next to each bay number:
| Rdy | battery at 3.8 V, ready for storage |
| Cold | battery cold |
| Wrm | battery warm |
| Hot | battery hot |
| Err | Error, press SET button for info |
| % | percentage of charge |
Charging or discharging may take several hours. The remaining time is displayed as Time to 3.8 V in the battery monitoring menu (instead of Time to Full).
To exit storage mode:
When batteries are ready for storage, they should be removed from the charger and placed into a temperature controlled area. Recommended battery storage temperature is 0°C (10°F) to 25°C (77°F).
A deeply discharged battery is one that has been discharged to less than 3.0 volts. When the charger detects a deeply discharged battery, it automatically enters recovery mode, which charges the battery using a reduced current. The Recovery icon is displayed next to the bay number on the home screen. If recovery is successful, the charger exits recovery mode and charges the battery to capacity. If the battery cannot be recovered in less than 30 minutes, Recovery Failed is displayed and charging stops.
Tip: Periodically charge batteries using the Storage Mode function to avoid deep discharge and to maintain the ideal battery storage voltage of 3.8 volts.
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and enhancements. To take advantage of design improvements, new versions of the firmware can be uploaded and installed using the Firmware Update Manager tool available in Wireless Workbench software. Firmware is available for download from www.shure.com.
| Warnings and Error Messages | Troubleshooting Solution |
|---|---|
| Cold | Charging stopped. Battery temperature must rise above 0° C for charging to resume. |
| Hot | Charging stopped. Battery temperature must cool below 60° C for charging to resume. Avoid direct sunlight and other heat sources. |
| Warm | Battery charging stops at 80 percent of full capacity. Allow battery to cool below 45° C to resume charging to full capacity. |
| Recovery | Charger has detected a battery that has been discharged below 3.0 volts and has entered Deep Discharge mode to recover the battery charge. |
| Recovery Failed | Battery discharged beyond recovery — replace battery. To avoid this condition, periodically charge batteries to prevent full discharge. |
| Charging Failed | Battery unable to charge within specified time frame. Check battery and contacts. If condition persists, replace battery. |
| Unknown Battery | Update the battery charger firmware |
| Unknown Module | Update the battery charger firmware |
| Read Error | Battery contacts may be dirty or damaged, preventing battery detection by the charger. Check that the battery contacts are clean and undamaged. If condition persists, replace the battery. |
| Check Charger | Check the battery contacts and charger module contacts to make sure they are clean and fully engaged. If condition persists, try substituting a functional battery or charger module. |
| Check Battery | Make sure battery is fully inserted in charger module and that module door is latched. Check battery contacts and charger module contacts to make sure they are clean. Replace battery if condition persists. |
| Over Temp! Check Fan/Vents | Remove any obstructions or debris from fan vents and ensure that there is sufficient airflow to the charger. |
Use energy efficiency mode to charge batteries with the display screen backlight and network functionality (including charging and battery information) disabled.
To resume normal operation, turn off the charger, wait 5 seconds, and turn it back on.
