Battery Backup for ECU Data
The TaoTao OBD2 memory saver plugs into a 12V vehicle's diagnostic port to maintain power to the ECU while the main battery is disconnected. A digital LED display shows real-time voltage so you can confirm the connection is live. Heavy-duty alligator clips and a 5A fuse provide a secure, protected link. The 6.0 in cable keeps the adapter within easy reach during the swap.
Suited for DIY Battery Swaps
This tool is ideal for owners and technicians who need to preserve radio codes, seat positions and fault-memory when changing a 12V battery on OBD2-equipped cars. It is not for anyone servicing vehicles without an OBD2 port or electrical systems that run on a different voltage. Buyers who need to keep high-draw accessories active during the procedure should look at a larger external power supply.
12V OBD2 Power Feed with Fused 5A Lead
The single deciding specification is the 12V OBD2 input combined with a 5A fuse rating; it determines whether the unit can safely sustain your vehicle's ECU load without tripping. If the car draws more than the fuse allows, the saver will disconnect and memory will be lost. Verify the vehicle's quiescent current before relying on this adapter.

Questions about this item
What type of vehicle power system is required for the 12V OBD2 memory saver to operate?
It works with most 12V vehicles that have an OBD2 port, drawing power through the diagnostic connector to keep the ECU alive while the main battery is disconnected.
Can the 6.0 in adapter remain plugged in while the original battery is removed and a replacement is fitted?
Yes, the quick-release OBD2 connector is designed to stay connected throughout the swap, supplying continuous voltage so radio codes, clock settings and ECU learned values are retained.
How does the digital display confirm the unit is protecting the vehicle memory during the battery change?
The LED readout shows real-time voltage at the OBD2 port; a stable 12V reading with the 5A fuse intact indicates the ECU is receiving uninterrupted power.
