SKU CH-6XXK-4HK4P

A 6-volt, 12-amp-hour sealed lead-acid battery with AGM technology for UPS replacement

  • 6 Volt 12 Ah capacity powers UPS systems reliably
  • Advanced AGM technology delivers maintenance-free sealed operation
  • 100% OEM replacement fits original equipment without modification
  • Gas recombination exceeds 90% for safe, non-spillable use
  • Expected service life of 4 to 7 years supports long-term backup

6 V 12 Ah UPS Replacement Battery

This 6 volt 12 amp hour sealed lead acid battery is built with advanced AGM technology for maintenance-free operation. It serves as a 100 percent OEM replacement for compatible uninterruptible power supplies and backup devices. The sealed construction prevents electrolyte leakage and allows safe use in any position. Expected service life ranges from four to seven years under normal float conditions.

Suitable Applications and Limitations

This unit suits users who need a direct drop-in battery for a UPS or backup system that specifies a UB6120 or AGM612 form factor. It is not for buyers who require a different voltage, a higher amp-hour rating, or a chemistry other than sealed lead acid. Installers needing user-serviceable cells or on-site electrolyte access should look elsewhere.

Critical Specification: 6 V 12 Ah Rating

The single specification that decides fitment is the 6 volt 12 amp hour rating combined with the UB6120 AGM612 case size. Verify that the original battery label matches these exact electrical values and physical dimensions before ordering. A mismatch in voltage or capacity will prevent proper charging and runtime performance.

Questions about this item

What does the 12 amp-hour rating mean for my UPS runtime?

The 12 Ah capacity indicates the total charge the battery can deliver; actual runtime depends on your UPS load and efficiency.

How does the sealed lead-acid AGM design affect installation orientation?

The sealed AGM construction prevents electrolyte leakage, allowing safe operation in any position without spill risk.

What are the physical requirements for fitting the UB6120 into my UPS unit?

The battery uses a standard 6 Volt form factor; verify your UPS compartment dimensions and terminal layout match before installation.
