Direct UPS replacement battery

The Battery Technology Inc. SLA24-BTI is a direct replacement cell for SU1400RM2U and SUA1500RM2U uninterruptible power supplies. It matches the OEM RBC24 specification so critical systems regain full runtime immediately. IT teams and facility managers use it to restore backup protection without replacing the entire UPS unit.

Steady voltage under continuous discharge

The sealed lead-acid chemistry delivers consistent voltage throughout extended outages rather than sagging after an initial burst. This behaviour keeps connected servers and network gear stable until utility power returns or a graceful shutdown completes. The design supports the sustained loads typical of rack-mounted infrastructure.

Slide-in installation with polarity key

The battery slides into the UPS chassis using the original connector layout, so no tools or wiring changes are required. The keyed terminals prevent reverse-polarity connection, which is the most common error during swap-outs. Installers should verify the RBC24 label on the old pack before fitting the new module.

Questions about this item

How much heat or noise does the SLA24-BTI generate during continuous operation?

The SLA24-BTI is a sealed lead-acid battery with no moving parts, so it produces no fan noise and negligible heat during normal float charging.

What existing UPS hardware is required to install the SLA24-BTI?

You must already own an APC Smart-UPS SU1400RM2U or SUA1500RM2U, or any unit that uses the RBC24 cartridge, because the SLA24-BTI is a direct replacement for that specific battery pack.

Will the SLA24-BTI work in an older SU1400RM2U that has been running on its original RBC24 for several years?

Yes, the SLA24-BTI matches the RBC24 form factor and voltage, so it fits the older SU1400RM2U or SUA1500RM2U without modification and restores the original runtime.
