6V 12Ah SLA Battery for UPS & Alarms

This 6-volt 12-ampere-hour sealed lead-acid battery uses advanced AGM technology to deliver maintenance-free backup power. It is built as a 100 percent OEM replacement for compatible UPS units, emergency lighting, fire panels, security alarms and pumps. The sealed construction prevents electrolyte leakage and allows safe operation in any orientation.

Suits direct replacement in listed devices.

Buyers needing a drop-in 6V 12Ah SLA cell for the equipment named above will find the correct fit and expected service life of four to seven years. Systems that require a different voltage, capacity or chemistry should look at another product because this unit only matches the stated specification.

Verify voltage, capacity

Confirm that your existing UPS, alarm panel or pump specifies a 6V 12Ah SLA battery and that the physical dimensions and terminal arrangement match the original unit. The 90 percent gas recombination and non-spillable rating support any-position mounting, but the device must be designed for this exact electrical profile.

Questions about this item

What voltage and capacity must the UPS or alarm panel supply to use this 6 V 12 Ah SLA battery?

The unit must provide a 6 V charging circuit rated for a 12 Ah sealed lead-acid battery; the battery is a direct 100 % OEM replacement for that specification.

Can this AGM battery sit beside older flooded lead-acid cells in the same string?

No, mixing AGM with flooded chemistry causes charge imbalance and shortens life; replace the whole string with matching AGM units.

How do I verify the battery is working after installation?

Measure open-circuit voltage — it should read about 6 V — then confirm the UPS or alarm panel shows a healthy charge status and runs its self-test without fault.
