Product Identity

Compatibility Check

Verify that your device requires a 12 volt battery with an 18Ah rating and accepts nut-and-bolt terminal connections. The unit measures 7.13 in long, 3.00 in wide and 6.6 in high, so confirm the compartment can accommodate those dimensions. Cross-reference the listed replacement models such as Powersonic PS-12180, Yuasa NP18-12B or CSB GP12170 to ensure an exact match.

Build Integration

The battery delivers 12.5 lbs of deep-cycle energy storage and fits into existing UPS, alarm, exit sign or scooter enclosures without modification. Its sealed construction allows operation in any orientation and eliminates the need for watering or venting. Once installed it restores full backup runtime and frees the system from reliance on degraded cells.
