SKU CH-X8B4-EKA0H

12 V AGM UPS replacement battery with sealed, maintenance-free design and over 90 % gas recombination

  • Reliable power with advanced AGM technology
  • Up to 7 years expected battery life
  • 100% OEM compatible replacement fit
  • Maintenance-free sealed construction prevents leaks
  • Over 90% gas recombination for safety

Direct Replacement

The UB12100-S is a sealed 12 V AGM battery built as a 100 % OEM replacement for compatible UPS units. It uses absorptive glass mat technology to deliver maintenance-free operation without electrolyte checks or water top-ups.

Sealed Safety

The sealed construction prevents electrolyte leakage from the terminals or case in any mounting position. Gas recombination handles over 90 % of generated gas during normal use, and the unit meets IATA non-spillable classification for safe transport.

Long Service Life

Expected floating service life spans four to seven years depending on operating conditions. The maintenance-free design requires no specific gravity checks or water additions throughout that period.

Questions about this item

How do I install the UB12100-S battery in my UPS and which step is most often missed?

Disconnect the UPS from mains power, open the battery compartment, remove the old unit, connect the new battery terminals observing the correct polarity, secure the battery in place, close the compartment and restore power; the step most often missed is verifying terminal polarity before tightening the connections.

What maintenance or replacement will the UB12100-S need during its service life?

The battery is maintenance free with no provision for checking electrolyte or adding water; it uses AGM technology with gas recombination and has an expected floating service life of 4 to 7 years after which replacement is required.

What is the first limitation that appears when the UB12100-S is used continuously under load?

Under sustained discharge the 12 V output voltage will decline as the stored energy is depleted, and the battery cannot be recharged until the UPS returns to mains power, making runtime the primary limit.
