Auto Meter SPS-12 Memory Saver, Smart Power System

The SPS-12 Smart Power System provides power through the vehicle’s OBDII port or 12v outlet (with optional adaptor) to keep vehicle computer systems supplied with power when the battery is disconnected or removed. The SPS-12 also accurately monitors for parasitic electrical draw that could cause the battery to discharge when the vehicle is not in use. Also preserves your customer’s radio/infotainment settings, memory and engine/transmission adaptations.


  • Simple, plug and play operation. 
  • Direct AC power connection insures 100% uptime during battery-out service with no need to  charge unit. 
  • Purpose built to provide regulated voltage ensuring safe operation while converting 120 VAC to 14VDC.
  • OBDII or optional 12v outlet adapter (AC-75) (Sold Separately) ensures compatibility with nearly all vehicles making the SPS-12 extremely versatile.
  • Maintain Seat Positions, Radio Stations, and Vehicle Settings.
  • Convenient Hand Held Design.
