Automotive Memory Saver to Prevent Data Loss

Automotive memory saver devices like the EZ-RED EZR-MS4000 are the trusted way to retain vehicle settings when swapping batteries. If you’ve ever lost radio presets, TPMS calibrations, or alarm codes after a battery disconnect, you know the hassle.

• Clear green/amber LEDs indicate active or low-voltage status
• Internal 120V charger included - just plug and recharge
