BatteryJack inc. UB6120 6V 12Ah UPS Replacement Battery 2 Pack

SKU CH-CHF3-AETYK

Two 6 V 12 Ah sealed lead-acid batteries with AGM technology and over 90 % gas recombination

  • Two-battery pack keeps critical UPS units running
  • AGM technology delivers steady power without electrolyte leakage
  • Maintenance-free design eliminates water checks for years
  • 100 % OEM replacement fits existing 6 V 12 Ah slots
  • Gas recombination recycles over 90 % of generated gas

Two-pack 6 V 12 Ah UPS replacement cells

This lot supplies two sealed lead-acid batteries rated at 6 volts and 12 amp-hours each. They are direct OEM replacements for the UB6120 form factor used in many uninterruptible power supplies. Buyers who need a different voltage, capacity or chemistry cannot use this pack.

AGM sealed design with gas recombination

Absorptive glass mat construction absorbs the electrolyte so no leakage occurs from terminals or case in any orientation. The sealed build allows over 90 percent of generated gas to recombine during normal operation. No water topping or specific-gravity checks are required throughout the service life.

Maintenance-free operation and long float life

The batteries are classified as non-spillable for safe transport and can be installed in any position. Expected floating service life spans four to seven years. A three-year warranty covers UPS and backup devices while a two-year warranty applies to other applications.

Questions about this item

How do I install the UB6120 batteries and which step is often missed?

Install each 6 V 12 Ah battery upright or on its side; the step people miss is tightening the terminal bolts to the torque value in the UPS manual so the AGM seal stays leak-free.

What maintenance or replacement will the UB6120 pack need later?

The sealed AGM cells are maintenance-free for their 4-7 year design life; after that period both units should be replaced together to keep the UPS runtime balanced.

What limit appears first when the UB6120 batteries run under sustained load?

Gas recombination handles over 90 % of generated gas, so the first limit is the gradual capacity fade that defines the 4-7 year service life rather than venting or dry-out.
