OBD2 Memory Protector Connector ECU Connector Emergency Memory Protector with Alligator Clips Battery Replacement Tool Universal

Does exactly what it should. Easy to use and save having to recode radio, re input channels, sat nav when changing the car battery.

This is an excellent piece of kit. I plugged it in , connected to a spare battery and saved all my cars settings whilst I changed the battery. It doesn't push in very far to the OBD, so look for the white light to make sure its connected. One gripe is that the lead is short, you will need a spare battery. Pity the lead isn't longer then you could connect it to another car , should thee be one.

This item was not suitable for my car,but it looks as if it would do the job for most likely people

A well made obd2 plug with sturdy crocodile clips to use to retain the cars coded memory if changing the battery in the future. Just plug into the cars obd2 and connect to a spare battery to save all details without having to reprogram and saving you money and trouble of going to a garage. Easy to use and value for money and a good item for the toolbox.

Cable not long enough

as advertised

Whenever I'm doing some work on the car that requires the battery to be disconnected, I always need to recode the car radio. This tools is the solution for that. I can plug it into the OBD2 connector in the car and plug another battery on it and I won't need to recode the car radio again.

Great solution. I use an old motorcycle battery to power the device. Just plug it into the EOBD2 port and swap battery at your leisure. Save a fortune getting new battery coded to your car with this simple solution. Great value too.
