12V 18Ah UPS Replacement Battery

This 12V 18Ah sealed AGM battery serves as a direct replacement for UPS units and backup power systems. It uses advanced AGM technology for maintenance-free operation and fits devices requiring the BP17-12 or GP12170 form factor. The unit arrives new and ready to install with nut and bolt terminals included.

Replaces 12V 15Ah to 20Ah SLA models

It replaces a wide range of 12V batteries from 15Ah to 20Ah including Yuasa NP18-12B, CSB GP12170 and Panasonic LC-R12V17P. The jump is worth it when your existing pack has reached the end of its 4 to 7 year expected life or shows reduced runtime. Compatibility covers fire alarms, security systems, exit signs, scooters and mobility chairs.

Check voltage dimensions and terminal type

Verify that your equipment requires a 12V block with 7.13 in length, 3.00 in width and 6.6 in height. Confirm the device accepts nut and bolt terminals and that the 12.5 lb weight fits the mounting tray. Ensure the application matches the listed uses such as UPS backup, testing equipment or electric gates.

Questions about this item

What are the exact dimensions of the 12V 18AH battery so I can confirm it fits my UPS tray?

The battery measures 7.13 in length, 3.00 in width and 6.6 in height, weighing 12.5 lbs. Verify your compartment allows at least these clearances.

How do I attach the nut-and-bolt terminals and what is the common mistake?

Fasten the supplied nuts onto the bolt terminals to the recommended torque; the frequent error is leaving them finger-tight, which increases resistance and heat.

When should I plan to replace this 12V 18AH AGM battery based on its expected service life?

The manufacturer states an expected life of 4 to 7 years; schedule a capacity test at the 4-year mark and budget for replacement before year 7.
