Direct Replacement for APC Back-UPS ES 725VA

This 12V 7.5Ah sealed AGM battery is a 100% OEM-compatible replacement for the APC Back-UPS ES 725VA unit. It fits the original battery compartment using the existing T1/T2 terminal connections. The maintenance-free design requires no user servicing after installation. It restores backup power capability for connected broadband and networking equipment.

Sustained Discharge with AGM Chemistry

Advanced AGM technology delivers stable voltage output during extended power outages rather than only brief interruptions. The absorbed glass mat construction minimises internal resistance, allowing consistent current flow over the full discharge cycle. Expected service life ranges from four to seven years under normal float conditions. The sealed design prevents electrolyte stratification during prolonged standby periods.

Low Heat and Silent Operation

Sealed AGM construction generates minimal heat during normal float charging and standby use. No cooling fans or active ventilation are required, resulting in completely silent operation. The compact dimensions of 5.94 by 2.56 by 3.66 inches allow the battery to fit the original enclosure without airflow modification. Power draw during recharge remains within the UPS charger's standard output limits.

Questions about this item

Does the 12 V 7.5 Ah AGM battery run silently and without extra heat in the APC Back-UPS ES 725VA?

Yes. The sealed AGM design has no moving parts, so it produces no audible noise and adds no measurable heat during continuous float charging.

What existing hardware is required to install this 12 V 7.5 Ah replacement in the APC Back-UPS ES 725VA?

You need the original UPS chassis with its T1/T2 terminal connectors and the factory battery compartment that accepts the 5.94 × 2.56 × 3.66 inch form factor.

Will the 12 V 7.5 Ah unit charge correctly on the older APC Back-UPS ES 725VA charging circuit?

Yes. It is a 100 % OEM-specification match for the 725 VA model, so the existing charger regulates voltage and current exactly as designed.
