(Jackie F., Gerardo M.)

Replaced the old batteries on the UPS units at both mid stations, both end stations, and two at the corner station.
The UPS units are dedicated supplies for the vacuum racks, the following racks were updated today:

• Corner station, h0vaclx (located by the X-beam manifold) and h0vacmr (located in the mechanical room).
• X-Mid, h0vacmx
• Y-Mid, h0vacmy
• X-End, h0vacex
• Y-End, h0vacey

No issues were encountered.  One set of batteries had been already installed previously, see aLOG 83151.
