Replacing a modern vehicle's battery without a backup power source can lead to frustrating data loss and system errors. This Universal OBD2 Automotive Battery Replacement Tool is designed to maintain your vehicle’s computer memory and electronic settings during the battery swap process. By providing a continuous power bridge, it ensures that your ECU (Engine Control Unit) and peripheral systems remain active, preventing the need for tedious manual resets.

Modern vehicles rely heavily on persistent memory to store everything from basic clock settings to complex transmission shift points and safety system calibrations. This tool plugs directly into your vehicle’s OBD2 port, acting as a temporary power link that keeps your settings intact, saving you time and preventing potential trips to the dealership for system re-initialization.

Vehicle Compatibility

• Compatible with all vehicles equipped with a standard 16-pin OBD2 port (typically 1996 and newer)
• Supports 12V electrical systems
• Works for Sedans, SUVs, Trucks, and Hybrid models

Key Benefits & Data Protection

Electronic System Retention: When the main battery is disconnected, the memory saver preserves critical data across multiple modules. Without this tool, disconnecting the battery can result in the loss of "learned" engine data, which may cause rough idling or poor performance until the vehicle re-learns its parameters.

Convenience & Comfort: This tool ensures that all user-defined settings remain exactly as you left them. This includes your personalized digital clock, stereo presets, and navigation history, as well as high-end comfort features like memory seat positions and electric mirror calibrations.

Protected Systems Include

• Dashboard Information: Trip meters and diagnostic data
• Digital Clock: Maintains accurate time settings
• Stereo Settings: Radio presets, EQ levels, and Bluetooth pairings
• Memory Seats & Mirrors: Saved driver profiles and mirror angles
• Safety Modules: ABS (Anti-lock Braking) and Anti-skid system calibrations
• Power Windows: Prevents loss of "auto-up/down" one-touch functionality

Construction & Materials

High-Quality Wiring: The tool features heavy-duty, insulated copper wiring to ensure stable current delivery and prevent voltage drops during the replacement process. The flexible cable design allows for easy maneuvering within the footwell and engine bay.

Precision OBD2 Connector: The 16-pin interface is manufactured to strict tolerances for a secure, snug fit into the vehicle's diagnostic port, preventing accidental disconnection while you are handling the heavy main battery.

Features & Components

• Universal 16-pin OBD2 connector interface
• Maintains ECU memory to avoid "Check Engine" lights or rough idling
• Preserves security codes for anti-theft radio systems
• Maintains power window and sunroof limit settings
• Fused circuit protection to prevent electrical surges
• LED indicator light (on select models) to confirm a secure connection
• Durable, heat-resistant housing for workshop environments

What's Included

• 1× Universal OBD2 Battery Memory Saver Cable
• Integrated 12V power adapter (Cigarette lighter plug or Battery Clip-on)
• User Safety & Instruction Manual

How To Use (Installation)

• Step 1: Connect the tool to a secondary 12V power source (another vehicle or a portable jump starter).
• Step 2: Plug the OBD2 connector into the vehicle's diagnostic port (usually located under the driver-side dashboard).
• Step 3: Ensure the connection indicator is active, then proceed to remove the old battery.
• Step 4: Install the new battery and tighten the terminals.
• Step 5: Disconnect the OBD2 tool and the external power source.

Pro Tip: Always ensure the secondary power source has a full charge before starting the process. Avoid opening vehicle doors or turning on high-draw accessories (like headlights or AC) while the battery is disconnected, as the memory saver is only designed to provide low-amperage support for memory modules.

Safety Requirements

Caution: When using this tool, the positive battery cable remains "live" even when disconnected from the battery. Wrap the positive terminal in a rag or insulating sleeve during the swap to prevent it from touching the vehicle chassis and causing a short circuit.
