12V 18Ah AGM Battery

This 12V 18Ah sealed lead-acid battery uses advanced AGM technology for maintenance-free operation. It serves as a direct OEM replacement in UPS units, alarm panels, emergency lighting and mobility equipment. Nut and bolt terminals provide a secure connection for demanding backup applications.

Deep-Cycle Sustained Output

The AGM construction delivers steady current over long discharges rather than short bursts, making it suited for extended runtime during power outages. A design life of four to seven years supports reliable cycling in security systems, exit signs and electric scooters without routine maintenance.

Terminal And Dimension Check

Verify that your device accepts nut and bolt terminals and that the 7.13 in length, 3.00 in width and 6.6 in height fit the battery compartment. Confirm the required voltage is 12V and the capacity rating matches the 18Ah specification before ordering.

Questions about this item

Does the 12V 18Ah sealed lead-acid battery generate noticeable heat or noise during continuous UPS operation?

The AGM construction is sealed and maintenance-free, so it runs silently with no moving parts; normal warmth occurs under load but excess heat only appears if the charger voltage is set incorrectly.

What terminal hardware must already be on the UPS or device for the nut-and-bolt posts to connect?

The battery ships with M5 or M6 threaded posts; you need matching ring or spade lugs and the correct bolt length to torque them to the manufacturer's specification.

Will this 18Ah pack work as a direct drop-in for the Yuasa NP18-12B or CSB GP12170 currently in my cabinet?

Yes — it matches the 12 V 18 Ah rating and the 7.13 × 3.00 × 6.6 in footprint of those models, so it fits the same tray and uses the same nut-and-bolt terminals.
