Connecting DC Power

  1. Connect the cable from the Shure PS51 power supply to the DC power supply input.
  2. The white LED will illuminate when the PS51 is connected to an AC power source.

Inserting and Removing SB900 Batteries

To Insert:

  1. Align with the key-way and press the battery into the charger bay.
  2. Close charging bay door and slide tab to the left to lock in place.

To Remove:

Slide tab to the right and open battery door. Remove battery from charger.

Charging Batteries

Slide the battery into the charging bay. Charging begins as soon as the charger door is closed and locked into place.

Charge Status LED

Each charger bay has an LED to indicate the status of the battery.


battery charging


charging complete


battery inserted incorrectly or battery depleted below 3.0 volts.


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.

Recovering a Battery from Deep Discharge

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. A red LED indicates recovery mode. 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, the red LED turns off and charging stops.

Changing the Charger Module

Caution! Remove DC power and remove batteries when installing the charging module.

  1. Remove the 4 mounting screws that secure the charging module.
  2. Pull the charger module to remove it from the housing.
  3. Insert the replacement charger module into the housing (note the orientation of the guide rails).
  4. Insert the mounting screws (4 pieces) and tighten them to secure the charging module.
