BatteryJack inc. UB12100-S UPS replacement battery 12V 10Ah

SKU CH-QFZM-G6FBS

Sealed lead-acid UPS replacement battery delivering 12 V and 10 Ah capacity with maintenance-free AGM design

  • 12 V 10 Ah capacity keeps UPS runtime reliable
  • Advanced AGM technology delivers maintenance-free operation
  • 100 % OEM replacement fits original equipment exactly
  • Expected service life of 4 to 7 years
  • Three-year warranty backs UPS and backup devices

Purpose & Fit

The BatteryJack inc. UB12100-S is a 12V 10Ah sealed lead acid battery designed as a direct OEM replacement for compatible uninterruptible power supply units. It serves administrators and technicians who need a maintenance-free AGM cell to restore runtime in existing power protection systems. Buyers requiring higher capacity or alternative chemistries will not find a match here.

Sustained Load Behaviour

Advanced AGM technology delivers consistent voltage output during extended discharge cycles rather than only brief backup bursts. The sealed construction eliminates electrolyte maintenance while supporting the 4 to 7 year expected service life under normal float conditions. Performance remains stable across repeated deep discharge events typical of utility outage scenarios.

Interface & Practical Limits

The 12 Volt 10Ah rating defines the energy envelope available to the connected UPS electronics. Physical terminal layout and case dimensions must align with the original equipment bay for proper installation. Systems engineered for different voltage windows or ampere hour ratings cannot accept this unit without redesign.

Questions about this item

How much heat does the 12 V 10 Ah sealed lead-acid battery produce when it runs continuously in a UPS?

The AGM design is maintenance-free and sealed, so it vents very little gas and generates minimal heat during normal float charging and occasional discharge cycles.

What connectors or cables must I already have to install the UB12100-S replacement battery?

The unit uses standard F2 spade terminals; you will need matching F2 leads or an adapter harness that fits your UPS battery compartment.

Will the 12 V 10 Ah AGM cell work in an older UPS that originally shipped with a lower-capacity battery?

Yes, as long as the physical dimensions match the original tray and the charger is rated for 12 V sealed lead-acid chemistry, the 10 Ah capacity simply provides longer runtime.
