[CentOS] UPS batteries, resolved

Well, whoever (or whoevers) recommended BatterySharks, thank you. I just
got the order today, a bit sooner than I expected, and it was *exactly*
what I'd asked for (HR batteries, all of them) and at their open market
price, it was *low*, so it saved a non-defense sector of the US federal
gov't a nice chunk o' change.

Thanks.
