Altronix SMP16PMC12X Compatible Battery Kit

This kit provides two 12V 12A sealed lead-acid batteries designed as direct replacements for Altronix SMP16PMC12X security system power supplies. It suits installers and maintainers who need to restore backup power to alarm panels and access-control units. The pack contains exactly two high-rate discharge cells ready for series connection.

Sealed design runs without active cooling

The valve-regulated construction eliminates fan noise and requires no external ventilation in normal operation. Each 12V 12A unit delivers its rated capacity through low internal resistance, keeping self-heating minimal during float charge. No moving parts mean silent performance inside locked enclosures.
