Replacement for APC UPS 1100SE

This 12V 2.3Ah sealed lead acid battery is a direct replacement for the APC UPS 1100SE. It uses AGM valve regulated technology so it can be mounted in different positions without spilling. The calcium alloy grid reduces electrolyte loss for consistent performance. It arrives factory fresh in a single pack.

Sustained backup performance

The 2300 mAh capacity delivers reliable runtime during extended power outages. Voltage matching from the same manufacturing batch keeps cell balance tight when multiple units are used together. This matching supports stable voltage output over the full discharge cycle. The result is dependable backup for critical equipment.

Thermals and power draw

The rugged ABS casing resists shock, vibration, chemicals and heat during normal operation. Valve regulated construction prevents gas build up and keeps internal pressure low. U.L. recognised and CE rated components meet recognised safety standards. Manufacturing in ISO 9001 certified factories ensures consistent quality control.

Questions about this item

How much heat does the 12V 2.3Ah sealed lead-acid battery generate during continuous UPS operation?

Sealed lead-acid chemistry runs cool under normal float charge; the ABS casing resists heat and chemicals, so no active cooling is needed inside the APC 1100SE.

What must I already own to install this RG1223T1 pack?

You need an APC UPS 1100SE with the correct battery compartment and terminal layout; the pack ships ready to connect with no extra cables or tools required.

Will this 7.01 x 1.38 x 2.40 inch battery fit the same tray as the original APC unit?

Yes, the dimensions match the standard 1100SE battery cavity, and the valve-regulated spill-proof design allows installation in the original orientation or on its side.
