Direct replacement battery

This 12 V 7.5 Ah sealed lead-acid unit fits devices that specify the 12120 form factor. It serves UPS units, alarm panels, emergency lighting and similar standby power applications.

Maintenance-free AGM design

Absorbent glass mat construction eliminates watering and allows operation in any orientation. The sealed case prevents electrolyte leakage during normal float or cyclic use.

Terminal flexibility included

Both T1 and T2 terminal types are provided so the battery connects without adapter cables. The three-year warranty covers UPS and backup installations, while other uses carry a two-year replacement period.

Questions about this item

How do I install the ESW-SLA-12V7.5 and which terminal step is often missed?

Match the T1 or T2 terminal to your device connector, secure the 5.94 by 2.56 by 3.66 inch case in the battery tray, then torque the terminal bolts to the device specification so the AGM cells stay sealed.

What replacement will the ESW-SLA-12V7.5 need after its service life?

The sealed AGM design is maintenance free for its 4 to 7 year expected life; after that the whole 12V 7.5AH unit is replaced with an identical 12120 size battery.

What limit appears first when the ESW-SLA-12V7.5 runs under continuous load?

Sustained discharge heats the AGM electrolyte, so voltage drops below usable levels once the 7.5 ampere hour capacity is depleted.
