Direct UPS replacement

This 12 V 12 Ah sealed lead-acid battery is a direct OEM replacement for the PS-12120F2 model. It uses advanced AGM technology and requires no maintenance during its service life. The unit is designed for uninterruptible power supplies, emergency lighting, alarm systems and similar backup applications.

Fits standard battery trays

The battery measures 151 mm long, 98 mm wide and 95 mm high in the container, with a total height of 101 mm including the terminal. These dimensions allow it to slide into existing UPS compartments without modification. At approximately 4.20 kg it adds minimal weight to rack or tower installations.

Low self-discharge design

AGM construction limits self-discharge so the battery holds charge during long standby periods. Normal float operation produces no gas emissions and runs silently. Expected service life ranges from four to seven years depending on temperature and cycling frequency.

Questions about this item

How long will the PS-12120F2 last before capacity drops under continuous float charging?

The manufacturer states an expected service life of four to seven years when the battery is kept on float charge at room temperature.

Does the sealed lead-acid design produce any gas or heat that requires ventilation during all-day operation?

The AGM construction recombines gas internally and the battery is rated maintenance-free, so no forced ventilation is needed for normal UPS duty.

What terminal type does the PS-12120F2 use so I can confirm it fits my existing UPS harness?

The unit measures 151 mm long, 98 mm wide and 101 mm total height with terminals, matching the standard F2 flag-terminal footprint used on many 12 Ah UPS packs.
