BatteryJack inc. UB12120 12V 12Ah UPS replacement battery

SKU CH-CYDE-BC8EC

A 12 V 12 Ah sealed lead-acid battery with AGM technology for UPS and emergency backup systems

  • Reliable backup power with 12 V 12 Ah sealed lead-acid capacity
  • Maintenance-free AGM design eliminates watering and spill risk
  • Exact 100 % OEM fit for drop-in UPS replacement
  • Compact footprint measuring 151 mm × 98 mm × 101 mm total height
  • Lightweight at 4.20 kg for easy handling and installation

Purpose and fit

This 12 V 12 Ah sealed lead-acid battery is built as a direct replacement for UPS units and similar backup power systems. It suits IT managers, facilities teams and anyone maintaining emergency lighting, alarm panels or communication equipment that requires a standard UB12120 form factor.

Capacity and headroom

The 12 Ah rating delivers reliable runtime for typical UPS loads during short outages and supports cyclic use in EPS or DC power supply roles. It is not designed for deep-cycle traction duties or high-current starting applications where a larger capacity or different chemistry would be required.

Thermals and power

AGM construction makes the battery maintenance-free and spill-proof, so it runs without venting gases under normal float charge. Self-discharge is low, allowing extended shelf storage, while the sealed design keeps operating temperatures stable inside standard UPS enclosures without added cooling.

Questions about this item

Will this 12 V 12 Ah UB12120 fit the same compartment as the battery I am replacing?

The case measures 151 mm long, 98 mm wide and 95 mm high, with a total height of 101 mm including terminals.

How can I confirm the battery is delivering its rated 12 Ah after installation?

Run a UPS self-test or a calibrated load test; the unit should hold the load for the expected runtime without a low-battery alarm.

Does the package include the two batteries shown in the photo or only one?

The listing describes a single 12 V 12 Ah unit weighing 4.20 kg; order two if your UPS requires a matched pair.
