Direct UPS Replacement

This 12 V 9 Ah sealed lead-acid battery replaces the original cell in compatible Eaton and Tripp Lite UPS units. It restores backup runtime for protected workstations, network gear and point-of-sale systems. The single-cell design fits the standard battery compartment without modification. Installation is user-serviceable with basic tools.

Compatibility Checklist

Verify that your UPS model appears in the supported list: IO700NAFTA, SMART600PSGLCD, OMNIPRO675, INTERNETOFFICE525, INTERNETOFFICE450, INTERNET700i, BCPROINT675 or BCPRO675. Confirm the existing battery is a 12 V 9 Ah unit with matching terminal layout. Units not listed may use a different voltage, capacity or form factor.

When to Swap

Replace the battery when runtime drops below acceptable levels or the UPS signals a battery fault. A fresh 9 Ah cell restores the original backup duration for the listed models. If your equipment demands longer runtime than the original specification, this direct replacement will not extend it.
