A word of caution (I was bitten by this): in many data centers, the USA National Electrical Code requires that UPS units be connected to the Emergency Power Off system so that in case of emergency the UPS will shut off too. Many of the less expensive UPS units do not have EPO shutdown capability, and it usually takes an electrician to wire it up when they do. There are also NEC regulations regarding batteries. - Brian
