Questions about this item

Does the AJC D8S kit include everything needed to swap the old UPS battery, or must I buy extra cables or connectors?

The kit supplies one 12V9A sealed lead-acid battery plus comprehensive installation instructions; no additional cables or connectors are required.

Should I choose the 12V9A version or is there a different capacity listed for this model?

Only the 12V9A capacity is offered for the AJC D8S, so that is the version to select.

What does the 12V9A rating mean for actual UPS runtime once the battery is installed?

The 12 volt, 9 amp-hour rating defines the energy the battery can deliver; real runtime depends on the UPS load and its power management settings.
