SDC SECURITY DOOR CONTROLS RB12V7 12V 7Ah security battery

Security Battery For Access Control

The SDC RB12V7 is a 12V 7Ah sealed lead-acid battery designed to provide backup power for security door controllers and alarm panels. It suits installers and facility managers who need a direct replacement cell for compatible enclosures.

Fits 621PJ Enclosure Without Modification

The case is built to the dimensions accepted by the 621PJ housing, so the unit slides into the existing compartment and connects to the standard F2 terminals. No adapter brackets or cable extensions are required for a typical swap.

Holds Charge During Extended Mains Outage

Under continuous load from a door controller the cell maintains voltage for the rated ampere-hour span rather than collapsing after a brief surge. The chemistry is optimised for standby float service instead of cyclic deep discharge.
