MS4000C - Automotive Memory Saver Combo with Built-in Charger

The MS4000C Memory Saver uses a 12V, 4.5AH spill-proof sealed lead-acid battery to provide backup power to your vehicle while the battery is disconnected, either for service or replacement. The MS4000C cable plugs into the vehicle OBDII port to provide backup power for the vehicle's electronic systems to maintain memory and settings that might otherwise be lost when battery power is disconnected.
