Autel Battery Tester Memory Saver

Autel Battery Tester Memory Saver

The Autel Battery Tester Memory Saver connects to the vehicle's OBD-II port or accessory power to maintain a low-level power supply to the vehicle's electrical system while the battery is disconnected for service or replacement. This prevents loss of radio presets, window and seat memory positions, TPMS sensor data, and other system settings that are stored in volatile memory.

Why Use a Memory Saver During Battery Service

Modern vehicles store significant configuration data in memory that is lost when battery power is interrupted. The practical consequences for shops:

• Radio stations require re-entry by the customer
• Power window auto-up/down functions require re-initialization
• Sunroof, seat, and mirror positions may need reset
• Some vehicles require relearns for throttle body position, idle, and transmission adaptation after power loss
• On some platforms, power loss triggers security lockouts requiring dealer-level procedures to clear

A memory saver eliminates these issues by keeping a small amount of power flowing during the swap. At $45, it prevents comebacks that cost far more in time than the tool is worth.

Workflow

Connect the memory saver to the OBD-II port or accessory power socket before disconnecting the battery. Swap the battery. Reconnect the battery terminal and remove the memory saver. The vehicle's systems are intact and the customer drives away without complaints about lost settings.
