UPS Replacement Battery for APC BE650R

This 12V 9AH sealed lead-acid battery serves as a direct replacement for uninterruptible power supply units such as the APC BE650R. It uses AGM technology for leak-free operation in any orientation. The maintenance-free design suits server rooms, network closets and home-office backup systems that need reliable runtime during outages.

Voltage and capacity match

The single specification that decides fit is the 12V 9AH rating combined with T2 terminals. If your UPS requires a different voltage, amp-hour value or terminal type this unit will not connect or deliver the correct runtime. Verify the original battery label before ordering to avoid an incompatible installation.

Dimensions and warranty terms

Physical size is 5.94in length, 2.56in width and 3.72in height with a weight of 13.16lbs, so the battery must fit the existing compartment. A 24-month warranty covers defects, while a 30-day money-back guarantee allows return if the unit does not match the application. No cables or mounting hardware are included in the package.

Questions about this item

What does the 12V 9AH rating mean for my UPS runtime?

The 12-volt 9-ampere-hour capacity determines how long the battery can power your UPS during an outage; actual runtime depends on the connected load.

What interface does the UB1290 use and what does it limit?

It uses T2 terminals, a standard faston tab connection that limits installation to UPS units designed for that terminal type.

Will the 5.94 by 2.56 by 3.72 inch case fit my battery compartment?

The battery measures 5.94 inches long, 2.56 inches wide and 3.72 inches high; verify your UPS compartment matches these dimensions before ordering.
