Replacement battery for APC UPS models

This sealed lead-acid unit replaces the original battery in compatible APC Smart-UPS systems. It is built for IT administrators who maintain rack-mounted or tower units in server rooms and network closets. The battery arrives ready to install without additional preparation.

Sealed lead-acid chemistry under continuous float

The cell is designed for long-term float service rather than repeated deep cycles. It delivers steady voltage during extended outages and recovers reliably after discharge events. Internal construction resists swelling and electrolyte loss over multi-year deployments.

Compatibility limited to listed APC part numbers

This pack fits APC models DLA1500RM2U, SU1400RM2U, SUA1500RM2U, Smart-UPS 5000I, 5000R5IBX and 5000RM. It will not work in units that require a different RBC reference or voltage configuration. Verify the exact model label before ordering.

Questions about this item

How much heat does the lead-acid cell produce during continuous UPS operation?

Sealed lead-acid chemistry runs cool under normal float charge; the battery only warms noticeably during heavy discharge or recharge cycles.

Which APC Smart-UPS models accept this RBC25 pack without extra cables or trays?

Direct fit for APC Smart-UPS 5000I, 5000R5IBX, 5000RM, DLA1500RM2U, SU1400RM2U and SUA1500RM2U — no additional hardware required.

Will the replacement pack work in an older SU1400RM2U that still uses the original APC battery?

Yes — the BTI unit meets or exceeds the original specifications, so it drops into the existing SU1400RM2U chassis and connects to the same terminals.
