A new heavy duty (HD) battery, NSN 6130-01-691-0809, for the AN/PYQ-10A(c) Simple Key Loader (SKL), is scheduled to replace the current HD battery, NSN 6130-01-525-2788, for all newly-produced SKLs by November 30, 2021, and as a replacement battery for already-fielded SKLs.

The current HD battery will continue to be issued until the stock is depleted. The new HD battery is modified to extend shelf life to five (5) years and allow for longer use.

The new HD battery is equivalent to the current HD battery, except the SKL must be updated to user application software (UAS) 14.1 for the new HD battery to display its current charge level.

Note that the new HD battery is not a replacement for the standard duty battery, NSN 6130-01-525-1635, nor does the current standard duty battery currently have an obsolescence issue like its HD counterpart.

All approved versions of the SKL UAS and supporting documentation, including the newest v14.1 (once released), can be found on the LandWarNet (LWN) website at (have your CAC handy):
