Units should immediately replace the hold up battery (HUB) when the Days Remaining message displays on the receiver/transmitter (R/T).
As a reminder, the HUB is essentially a backup battery designed to retain Type 1 initialization and mission plan information when the main battery has been depleted or detached. The AN/PRC-158 R/T has a HUB life of 365 days. The AN/PRC-162 R/T has a HUB life of 180 days.

Both R/Ts will provide a warning of diminishing HUB capacity in the form of a Days Remaining message. HUB warnings will display if the battery life is within 15 days of expiration for the AN/PRC-158, and 30 days for the AN/PRC-162.
Don’t remove the main battery while the HUB is depleted or it will result in a loss of Type 1 initialization. In this case, turn in the R/T so higher-level maintenance can restore the R/T to fully mission capable.

The HUB comes with NSN 6135-01-669-4691, PN LS14250 and CAGE code 7X634.  

Use the HUB replacement procedures and performance steps below when replacing the HUB on AN/PRC-158 and AN/PRC-162 R/Ts.

WARNING: Attach a fully charged main battery to the R/T when removing and replacing the HUB. Otherwise, the HUB’s removal and installation will require Type 1 initialization.

NOTE: The following procedures can be used on both R/Ts:

  2. Power on the R/T.
  3. Remove the HUB cover and O-ring from the R/T by turning the HUB cover counterclockwise. Retain the O-ring.
  4. Insert the new HUB into the R/T.
  5. Apply silicone grease to the O-ring.
  6. Install the O-ring and then the HUB cover and turn the HUB cover clockwise.
  7. Finally, reset the HUB capacity.
