Compatible Replacement Kit for OPTI-UPS DS1500B-RM

This kit supplies three 12V9A sealed lead-acid batteries built to match the original cartridge. It is intended for administrators maintaining an OPTI-UPS DS1500B-RM unit that needs fresh cells. The pack arrives factory-fresh with installation instructions included.

Three 12V9A High-Rate Cells

The defining specification is the trio of 12V9A high-rate discharge batteries that replicate the original cartridge voltage and capacity. No other voltage or ampere-hour rating is supplied, so the UPS must accept this exact configuration. The combined weight of the kit is 21.

Suits DS1500B-RM Owners Only

This package fits owners of the OPTI-UPS DS1500B-RM who need a direct drop-in refresh. Buyers with a different UPS model or a cartridge that requires a different voltage or capacity should look elsewhere. Installers who cannot follow the included instructions will also need an alternative solution.

Questions about this item

How long will three 12V9A batteries run a typical load in the DS1500B-RM?

Runtime depends on the connected load and the UPS efficiency curve; the kit supplies the rated capacity but the unit's firmware calculates the actual minutes available.

What connector standard do these replacement cartridges use to link with the UPS?

The batteries connect through the proprietary cartridge interface built into the DS1500B-RM chassis, matching the original wiring layout.

What are the physical dimensions of each 12V9A block so I can confirm they sit in the battery tray?

Each block follows the standard 12V9A SLA form factor used in the DS1500B-RM, allowing direct insertion into the existing battery compartment.
