Direct OEM Replacement for Parmak MAG12SP

This 6V 12AH sealed lead acid battery is built as a 100% OEM replacement for the Parmak MAG12SP unit. It uses advanced AGM technology to deliver reliable backup power for security and access-control systems. The maintenance-free design suits installers who need a drop-in swap without fluid checks.

Valve-Regulated AGM Build

The valve-regulated construction keeps the battery sealed and leak-resistant in any mounting orientation. Rugged ABS casing protects the cells from vibration and impact in outdoor enclosures. Maintenance-free operation removes the need for periodic topping up, reducing service visits over the expected 4-7 year service life.

Lead Acid Chemistry Limits

Sealed lead acid chemistry self-discharges during long storage, so a refresh charge is advised before commissioning after extended shelf time. Capacity falls at low temperatures, which can shorten runtime in unheated cabinets. The 12 Ah rating defines the energy envelope, so loads that exceed this draw will reduce backup duration.
