Ready-to-install UPS battery kit

The RefurbUPS ON300M601 kit supplies a pair of factory-fresh 12 V 7 Ah sealed lead-acid batteries pre-wired as a direct replacement cartridge. It is designed for administrators who need to restore runtime on compatible OneAC UPS units without sourcing individual cells.

Sealed lead-acid chemistry limits

SLA batteries deliver high-rate discharge for short outages but lose capacity permanently if stored discharged or exposed to sustained heat. Runtime scales with load, so the kit cannot support extended operation beyond the UPS rating.

Verify cartridge fit and connector match

Confirm the physical dimensions and terminal layout of the existing cartridge match the ON300M601 specification before ordering. The UPS must accept user-replaceable battery modules and the installation guide assumes standard screw-terminal access.

Questions about this item

Should I choose the ON300M601 kit or a different capacity for my UPS?

The ON300M601 kit supplies two 12 V 7 Ah SLA batteries wired for the original UPS voltage; select it only when your unit specifies that exact pack configuration.

What does the 12 V 7 Ah rating deliver once the batteries are installed in my UPS?

Each 12 V 7 Ah cell provides high-rate discharge current for short backup runtime; the pair maintains the UPS design voltage so runtime matches the original factory specification.

What connection standard does the ON300M601 kit use and what does it limit?

The kit uses the UPS manufacturer’s proprietary cartridge interface; it limits you to exact-fit replacement in compatible OneAC UPS models and prevents use with other brands.
