BatteryJack inc. 12V 12AH UPS Replacement Battery Replaces UB12150F2 12V 15AH

SKU CH-9DE5-PTC8T

12 V 12 Ah sealed lead-acid battery replaces UB12150F2 units in UPS and emergency backup systems

  • 12 V 12 Ah capacity keeps UPS running during outages
  • Direct replacement for UB12150F2 15 Ah models
  • AGM sealed design needs no watering or checks
  • 151 × 98 × 101 mm footprint fits standard battery trays
  • Three-year warranty covers UPS and backup devices

Direct Replacement for UB12150F2

This 12V 12AH sealed lead-acid battery is built with advanced AGM technology and serves as a 100 percent OEM replacement for the UB12150F2 model. It arrives new and maintenance-free, rated for an expected service life of four to seven years in uninterruptible power supply and emergency backup applications.

Suits UPS Units Accepting Lower Capacity

The battery fits systems that can operate with 12AH instead of the original 15AH rating, making it suitable for UPS, EPS, alarm, security and communication equipment where the reduced runtime is acceptable. Buyers who need the full 15AH capacity for longer backup duration should look at a higher-capacity alternative.

Simple Drop-In Installation

The unit measures 151mm length, 98mm width and 101mm total height with terminals, matching the UB12150F2 footprint so it seats directly in the existing tray. Verify the 12AH rating meets your runtime requirement before fitting, as the only common issue is reduced backup time compared with the original 15AH cell.

Questions about this item

Will this battery fit the compartment that currently holds a UB12150F2?

Yes, it matches the UB12150F2 footprint at 151 mm long, 98 mm wide and 95 mm container height with a total height of 101 mm including terminals.

Can I use this 12 Ah unit alongside my older 15 Ah batteries in the same UPS?

No, mixing capacities in a series string is not recommended because the 12 Ah cells will reach end of discharge before the 15 Ah cells, shortening overall runtime and stressing the smaller pack.

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

Run a controlled discharge test at the UPS rated load; the unit should sustain output for the calculated runtime based on 12 Ah before the low-voltage alarm triggers.
