BatteryJack inc. 12V 7.5AH 1290 standard battery

SKU CH-XRRJ-5QV3D

A 12 V 7.5 Ah AGM battery with sealed, maintenance-free construction for UPS and backup power

  • 12 V 7.5 Ah capacity powers equipment reliably
  • AGM sealed design prevents electrolyte leakage in any position
  • Gas recombination exceeds 90 % for maintenance-free operation
  • 100 % OEM replacement fits existing UPS and backup units
  • Expected service life of 4 to 7 years under float conditions

PowerStar PS-1290 12V 7.5AH Battery

The PowerStar PS-1290 is a 12 volt 7.5 amp-hour sealed lead-acid battery built with absorptive glass mat technology. It is designed as a direct OEM replacement for uninterruptible power supplies, alarm panels and emergency lighting systems. The maintenance-free construction requires no water top-ups and the sealed case prevents electrolyte leakage in any mounting position.

Ideal for UPS and backup power duties

This unit suits installers who need a reliable 12V 7.5AH block for standby float service where a 4 to 7 year design life is specified. It is not suited for cyclic applications that demand frequent deep discharges or for systems requiring a higher amp-hour rating than 7.5AH.

7.5AH capacity for standby loads

The 7.5AH rating comfortably handles typical UPS and security panel loads during short mains interruptions. Runtime decreases sharply under heavy continuous discharge and the battery reaches its practical limit when the connected equipment draws current well above the nominal rating for extended periods.

Questions about this item

What voltage system must my device use for this 12V 7.5AH battery to work?

Your device must operate on a 12 volt system. This battery supplies 12V and 7.5AH capacity, matching equipment designed for that voltage.

Can I use this 1290 model alongside older sealed lead-acid batteries in the same backup string?

Mixing batteries of different ages or capacities in one string is not recommended. This 1290 unit uses AGM technology and a 7.5AH rating; mismatched cells will charge unevenly and reduce overall runtime.

How can I confirm the PS-1290 is charging correctly after installation in my UPS?

The UPS should show a normal charge indicator and reach full runtime during a self-test. The battery is maintenance-free with gas recombination, so no electrolyte checks are needed.
