RefurbUPS Smart-UPS 750 DLA750 Compatible Replacement Battery Kit

Replacement Kit for Smart-UPS 750

This kit supplies two 12V 7A sealed lead-acid batteries fused together as a direct replacement for the Smart-UPS 750 (DLA750) unit. It matches the APC RBC48 specification so the UPS regains its original runtime without modification. Installers reuse the existing wiring harness, reducing waste and keeping the installation straightforward. The pack arrives factory fresh and includes step-by-step replacement instructions.

Sealed Lead-Acid Thermal Behaviour

The 12V 7A SLA cells operate without active cooling, so they add no fan noise to the rack or office environment. Under normal float charge they draw only the trickle current required to maintain full capacity, keeping power draw minimal. During a discharge event the batteries deliver high-rate current steadily until the UPS initiates its shutdown sequence. Because the chemistry is valve-regulated, there is no electrolyte maintenance or venting concern in typical indoor use.

Fused Pair Construction and Harness Reuse

The two batteries are permanently fused into a single block that fits the original battery compartment exactly, so no bracket changes or cable extensions are needed. Reusing the existing harness eliminates the risk of mis-wired polarity and saves the installer time on site. Comprehensive printed instructions guide the swap from power-down through self-test, making the procedure accessible to in-house IT staff without specialist tools. The kit suits facilities that prefer to maintain their current UPS fleet rather than replace entire units.
