SKU CH-388H-8YTGK MPN APCRBC106-SLA106

A 12 V lead-acid cell replaces APC RBC106 packs in Back-UPS BE400 and BGE90M units

  • Direct replacement for APC BACK-UPS BGE90M and BE400 series
  • Matches OEM part numbers APCRBC106 and RBC106 for guaranteed fit
  • 12V single-cell lead-acid chemistry delivers reliable backup power
  • New condition ensures full rated capacity from first use

Compatible 12 V replacement cell

This 12 V single-cell lead-acid battery replaces the APCRBC106 and RBC106 packs used in APC Back-UPS BGE90M and BE400 series units. It restores runtime for home-office and small-business UPS models listed by the manufacturer. Buyers needing higher-capacity packs or lithium chemistry should look elsewhere.

Simple drop-in installation

The cell fits the existing battery compartment without tools or wiring changes. Polarity markings on the terminals match the original pack to prevent reverse connection. The main risk is installing the battery in a UPS model not listed above, which can cause fitment or charging issues.

Questions about this item

How can I confirm the 12V lead-acid cell is holding charge after installing it in my APC BACK-UPS BGE90M?

After installation, let the UPS charge for the recommended period, then run a self-test from the front panel or management software; a passed test and normal runtime indicate the cell is working as intended.

Does the APCRBC106-SLA106 package include mounting brackets or cables, or must I reuse the original hardware from my BE400?

The replacement battery ships as a single 12V 1-cell unit; mounting brackets and connection cables are not included, so you will reuse the hardware already present in your APC BACK-UPS BE400.
