Tripp Lite OMNIPRO850 Compatible Battery Kit

This replacement kit contains three 6V12A sealed lead-acid batteries designed for the Tripp Lite OMNIPRO850 UPS. It restores backup power capability when the original cells reach end of life. The pack arrives factory fresh and includes comprehensive installation instructions for straightforward user replacement.

Suitable for OMNIPRO850 owners needing a direct swap

Buyers with a different UPS model or a different battery voltage requirement cannot use this kit. It is not intended for units that need a single cartridge or a higher ampere-hour rating. The three-battery configuration matches the original OMNIPRO850 layout only.

Includes three RBC52-compatible batteries

The bundled instructions walk through safe removal and installation without special tools. No additional cables, mounting hardware or monitoring software are supplied. The kit delivers the exact cell count and chemistry the UPS expects for reliable runtime restoration.

Questions about this item

Which UPS model must I already own for this 6V12A battery kit to fit?

Will the three 6V12A units work with the existing charging circuit in my OMNIPRO850?

How can I verify the kit is operating correctly once installed?
