BatteryJack inc. UB1290 12V 9Ah UPS Replacement Battery 2 Pack

SKU CH-TX09-FHTW9

Two 12 V 9.0 Ah AGM batteries replace APC UPS units from 200 VA to 600 VA with higher capacity and maintenance-free operation

  • Higher 9.0Ah capacity extends runtime versus 7.5Ah units
  • Advanced AGM technology delivers maintenance-free sealed operation
  • Direct replacement fits over 100 APC UPS models
  • 12V 1290 form factor matches original dimensions exactly
  • Two-battery pack enables full UPS refresh in one step

What this battery pack delivers

This two-pack supplies 12 V, 9.0 Ah sealed AGM units built as direct replacements for compatible APC UPS models. The advanced AGM construction raises capacity above older 7 Ah or 7.5 Ah cells while remaining maintenance free.

Verify fit and terminal type before ordering

Confirm your UPS appears on the supported model list that includes Back-UPS and Back-UPS Pro series from 200 to 600 VA ratings. Check that the existing batteries use T1 or T2 terminals and match the 5.94 × 2.56 × 3.66 inch footprint.

Thermal and power behaviour in service

Sealed AGM chemistry runs without venting and produces no audible noise during normal float or backup operation. Internal resistance stays low over the 4-7 year design life, so charge acceptance and voltage delivery remain stable under typical UPS loads.

Questions about this item

What comes in the 2-pack and is any wiring or hardware included?

The pack contains two sealed 12 V 9.0 Ah AGM batteries with T1/T2 terminals; no cables, brackets or mounting hardware are supplied.

My UPS originally used 7 Ah or 7.5 Ah cells — should I choose the 9.0 Ah version?

Yes — the 9.0 Ah units are direct 100 % OEM replacements that fit the same footprint and increase runtime through the higher capacity.

How much extra runtime does the 9.0 Ah rating give compared with a 7.5 Ah battery in an APC Back-UPS 500?

The 9.0 Ah cells store 20 % more energy, so a Back-UPS 500 will run proportionally longer under the same load.
