12V 8500mAh sealed lead-acid battery

The Power Sonic PS-1290F2 is a 12 volt 8500mAh valve-regulated lead-acid battery with F2 terminals. It is built for general-purpose and standby use in security panels, fire systems, medical devices, emergency lighting and UPS units. The sealed construction allows operation in any orientation without maintenance. New condition ensures full rated capacity from first installation.

Suits standby and cyclic duty in fixed installations

This battery fits equipment that specifies a 12V 9Ah VRLA block with F2 faston terminals, such as alarm panels, backup lighting and small UPS cartridges. It is not for buyers who need a higher capacity pack, a different terminal style such as F1 or threaded studs, or a lithium chemistry for weight-critical portable gear.

12 volt 8500mAh capacity with F2 terminals

The single specification that decides fitment is the 12V 8500mAh rating combined with F2 terminal tabs. Verify that the device calls for a 9Ah VRLA block and accepts F2 connectors before ordering.

Questions about this item

What comes in the box with the PS-1290F2 battery and what must I buy separately?

The box contains the sealed lead-acid battery with F2 terminals; cables, mounting hardware and a compatible charger are not included and must be sourced separately.

How do I decide between the 8500mAh capacity and other versions in the PS series?

Choose the 8500mAh model when your device specifies a 12V 9Ah requirement; higher-capacity PS units will not fit the same footprint and lower capacities will reduce runtime.

What does the 8500mAh rating mean once the battery is installed in a UPS or alarm panel?

It represents the total charge available at 12V; actual backup duration depends on the load your equipment draws, so a panel pulling 1 amp would theoretically run for about nine hours.
