A 12V 7.5AH sealed lead-acid battery using AGM technology for maintenance-free backup power

  • 12 V 7.5 Ah capacity powers UPS and backup gear
  • AGM sealed design prevents leaks in any orientation
  • 90 % gas recombination keeps operation maintenance-free
  • 100 % OEM fit replaces 12 V 7 Ah or 8 Ah units
  • Expected 4–7 year service life with three-year UPS warranty

12V 7.5AH SLA Replacement Battery

This 12-volt sealed lead-acid battery delivers 7.5 amp-hours of capacity using AGM technology. It serves as a direct OEM replacement for CP1290, 6-DW-9, HR9-12 and PS-1290F2 models. The maintenance-free design requires no water top-ups and operates safely in any orientation. It is built for standby and cyclic use in UPS, alarm and backup systems.

Suited for UPS and standby power.

Ideal for users needing a drop-in battery for uninterruptible power supplies, security panels or emergency lighting. The sealed, non-spillable construction meets IATA transport rules and recombines over 90 percent of generated gas. Buyers who require deep-cycle endurance for daily heavy discharge or a higher amp-hour rating should look at alternative chemistries or larger-capacity units.

7.5 Ah capacity with 4-7 year design life

The 7.5 Ah rating comfortably supports typical backup loads for several hours depending on draw. Expected service life reaches 4-7 years in float applications at moderate temperatures. Runtime shortens under sustained high-current discharge or elevated ambient heat. A three-year warranty covers UPS and backup deployments, while other uses carry a two-year term.

Questions about this item

Does this 12 V 7.5 AH SLA battery need a specific charger or will my existing UPS charge it?

The battery uses AGM chemistry and is designed as a direct replacement for 12 V 7 Ah or 8 Ah units, so the charging circuit already in your UPS or backup device will charge it correctly.

Can I mix this CP1290 battery with an older 12 V 7 Ah unit in the same string?

No, mixing capacities or ages in series or parallel strings creates charge imbalance and shortens life; replace all batteries in the string at the same time with matching 7.5 Ah units.

How can I confirm the battery is working after installation?

Run the UPS self-test or discharge cycle; the unit should hold the rated load for the expected runtime without triggering a low-voltage alarm.
