OBD II Connection

Designed to feed backup power through a compatible vehicle OBD II port during suitable battery-service procedures.

Voltage Display

Digital display helps you check the connected backup-source voltage before proceeding.

12V Service Use

Specified for 12V vehicle systems only; it is not intended for 24V electrical systems.

Supplier-Listed Protection

Supplier information lists reverse-polarity protection, but correct polarity and safe connection still need to be verified before use.

Reduce The Chance Of Losing Selected Settings

On compatible vehicles, a memory saver can help maintain certain clock, radio or electronic settings during battery replacement. It does not guarantee retention of every module or setting.

Use The Voltage Display As A Basic Confirmation

Confirm the backup power source is suitable and stable before disconnecting the vehicle battery. Follow the vehicle service procedure rather than relying on the display alone.

Not Every Vehicle Supports OBD Memory Saving

Consult the vehicle owner or service manual before use. Some vehicles, modules or service procedures may not permit backup power through the diagnostic port.

Use It For The Intended Battery-Service Task

Do not rely on this lead to diagnose parasitic drain, charging faults or other electrical problems that require proper test equipment.
