Hi Jesse,

from manual:

Replacing Controller Batteries
This procedure is different than installing batteries the first time the disk array is used, since replacing
batteries assumes that you have valuable data stored on your disk array. Many factors affect battery life,
including not only time of battery use, but also time of battery storage. Controller batteries should be
replaced every three years, or sooner if the display module indicates a constant â Battery Dischargedâ
message.
To replace controller batteries, do the following (see Figure 14):
CAUTION! If the disk array power is on, you should always perform a successful
Shutdown using the control panel to avoid loss of data before replacing a controller
battery. If a message appears on the control panel display indicating that the Shutdown
did not complete successfully, the disk array WILL LOSE DATA if you remove the
batteries. In this case, you should perform the following steps:
1. Install a second (functional) controller.
2. Wait about two minutes for the data to be posted from the controller with the bad
batteries to the second controller. The â Readyâ message appears at this time.
3. Remove the controller with the bad batteries, and install new batteries.
The controller batteries are Ni-Cad (Nickel Cadmium) type batteries. When replaced, these
batteries must be recycled or disposed of properly. Replace batteries only with the same
type.
1. Press down on the battery cover latch.
2. Remove the battery cover latch and RFI shield (if necessary, you can use a flat-bladed screwdriver to
remove the RFI shield).
3. Disconnect the cable from the controller PCA to ONE of the battery packs.
4. Replace the first battery pack with a new battery pack, and reconnect the cable.
5. Disconnect the cable from the controller PCA to the other battery pack.
6. Replace the second battery pack with a new battery pack, and reconnect the cable.
7. Reinstall the RFI shield and the battery cover latch.
