The AXT900 charges up to 8 Shure rechargeable batteries in a single, compact rackmount housing. Interchangeable charging modules accommodate any combination of handheld and bodyback transmitter batteries. The front panel display provides easy metering of all battery parameters, including charge status, time to full, battery health, and battery temperature. When connected to a network, parameters can be monitored remotely using Wireless Workbench.
This component is designed to fit into an audio rack.
WARNING: To prevent injury this apparatus must be securely attached to the rack.
This charger is only for use with Shure lithium-ion rechargeable batteries, such as the AXT910, AXT920, or AXT920SL.
AXT910 Bodypack Battery
AXT920 Handheld Battery
Bodypack Charging Module
Handheld Charging Module
Handheld and bodypack charger modules may be installed interchangeably into the charger.
Caution! Remove AC power and batteries when installing charger modules.
Each charger bay has an LED to indicate the status of the battery.
Red |
battery charging |
Green |
charging complete |
Off |
battery inserted incorrectly or battery depleted below 3.0 volts. |
Amber |
charging stopped at reduced capacity (not less than 75% capacity) because the battery is too warm. To reach 100% capacity, a battery must be cooled to below 45°C. |
Slide the battery into the charging bay until it locks into place. The charge LED illuminates and the charge cycle begins.
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, an error message is displayed and charging stops.
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 key 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).

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 display 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 key for info |
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:
Cold |
Charging stopped because battery temperature is too cold. Charging will resume when battery temperature increases. |
Warm |
Battery charging to less than full capacity (not less than 75%) because of elevated temperature. The amber LED will illuminate when charging has stopped. |
Hot |
Charging stopped because battery temperature is too hot. |
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 charge as a percentage of the total battery capacity. Also displays charge in milliampere-hours (mAh).
Displays both the battery temperature (in Celsius and Fahrenheit) and the status, as follows:
[Normal] |
Battery temperature = 0°C to 45°C (32°F to 113°F). |
[Cold] |
Battery temperature = 0°C (32°F) or lower. |
[Warm] |
Battery temperature = 45°C to 60°C (113°F to 140°F) . |
[Hot] |
Battery temperature = 60°C (140°F) or higher. |
Note: If warm or hot, try setting the fan to Always On or increasing ventilation to the rack.
Active |
Indicates connectivity with other devices on the network. |
Inactive |
No connectivity with other devices on the network. |
Note: IP address must be valid to enable networked control.
