M1-Series Tanks, ABV and Wolverine: Replace DECU Backup Battery

Read & heed this article: it could save you $27,000!

Dear Editor,
If the DECU volts or DECU backup battery in the M1-series tank, ABV or Wolverine are low, the DECU can be turned in to the Direct Support Electrical Systems Test Set (DSESTS) shop for repair.

But DSESTS personnel might not know they can replace the DECU backup battery instead of replacing the entire DECU. Like it says in WP-0164 of TM 9-2350-388-40-1 (Feb 09), DSESTS personnel can replace the backup battery and mandatory replacement parts, test the DECU, then return it to the unit.

Replacing a DECU costs about $30,000. But replacing the backup battery costs only around $2,400. As you can see, you can save a lot of money by replacing the backup battery instead of the DECU!
Units can order the backup battery installation kit with NSN 6160-01-632-8800.
