Two-pack 12 V 12 Ah AGM batteries

This product is a pair of sealed lead-acid batteries built with absorbent glass mat technology. Each unit delivers 12 volts and 12 ampere-hours of capacity for standby and cyclic use. The maintenance-free design suits uninterruptible power supplies, emergency lighting and security systems. They arrive new and ready to install.

Suits UPS and backup installations

These batteries fit equipment that requires a direct RBC4 form-factor replacement. They serve alarm panels, railway signals and DC power supplies where sealed construction is mandatory. Buyers who need higher ampere-hour ratings or a different terminal layout should look at other models. The two-pack quantity covers single-string replacements only.

12 Ah capacity per unit

Each battery provides 12 Ah at the 20-hour rate, supporting typical UPS loads for the expected 4 to 7 year service life. The 151 mm length, 98 mm width and 101 mm total height define the physical envelope. Installations with tighter dimensional constraints or greater energy demands will exceed the available space or runtime.

Questions about this item

What voltage and capacity must my UPS require for these 12 V 12 Ah RBC4 batteries to be compatible?

The pack contains two 12 V 12 Ah sealed lead-acid AGM units designed as direct OEM replacements for RBC4-spec UPS and backup devices.

Will the 151 mm length, 98 mm width and 101 mm total height fit the battery tray in my existing APC Smart-UPS?

Each battery measures 151 mm long, 98 mm wide and 101 mm tall with terminals, matching the standard RBC4 footprint used in many APC Smart-UPS models.

How can I verify the batteries are delivering power after installation?

The UPS should show a full-charge indicator, pass its self-test, and sustain connected loads for the expected runtime during a simulated outage.
