SKU CH-ZAQG-9EZNK

12 V 1.2 Ah sealed AGM battery replaces the Data Shield 1200 UPS unit with maintenance-free operation and over 90 % gas recombination

  • 12 V 1.2 Ah capacity powers Data Shield 1200 UPS units
  • AGM technology delivers maintenance-free operation with no electrolyte checks
  • Sealed non-spillable construction allows safe use in any orientation
  • Gas recombination design retains over 90 % of generated gas
  • 100 % OEM-compatible replacement fits without modification

What this battery is

The CA1212 is a 12 V 1.2 Ah sealed lead-acid battery built with AGM technology. It serves as a direct 100 % OEM replacement for the Data Shield 1200 UPS unit. The maintenance-free design uses absorptive glass mat separators and gas recombination to prevent electrolyte leakage in any mounting position.

Who it suits and who it does not

This unit suits administrators replacing a depleted cell in a Data Shield 1200 UPS that requires a 12 V 1.2 Ah form factor. Buyers needing a different voltage, capacity or physical size for another UPS model should look at other options. It is not intended for applications that demand user-serviceable electrolyte levels.

What to verify before ordering

Confirm that your UPS specifies a 12 V 1.2 Ah replacement and that the existing battery cavity accepts the CA1212 dimensions. Check the terminal layout and polarity against the original unit to ensure a correct fit. Verify that the device charging parameters match a sealed AGM cell with over 90 % gas recombination.

Questions about this item

Will the 12 V 1.2 Ah CA1212 fit inside my Data Shield 1200 UPS without modification?

The CA1212 is built as a 100% OEM replacement for the Data Shield 1200, matching the original 12 V 1.2 Ah specification and case dimensions so it drops straight into the existing battery compartment.

Can I keep my existing UPS charging circuit when I swap in this AGM battery?

Yes, the sealed AGM design uses the same 12 V float voltage as the original battery, so the UPS charger continues to operate normally without adjustment.

How do I confirm the new CA1212 is holding charge after installation?

After the UPS completes its self-test, check that the front-panel indicator shows a full-charge state and that the unit sustains its rated runtime during a brief load test.
