Automotive Battery Power Saver:

A car computer memory saver or power saver lead is used when it is necessary to disconnect the battery of the vehicle for replacement or access to other components. It is used to keep a constant power supply to the vehicle's electronic circuits and systems. Historically a power saver lead would plug into the cigar lighter socket.

Using a power saver:

It is important to use a battery power saver in order to save 'comfort' information such as: the time, date, radio security code, radio preset station settings, trip / driving information, personal speed warnings etc. More importantly to save the engine control module (ECM) parameters which may need 're-learning' if the power supply is interrupted. Also the continuous code for the key recognition may become out of synchronisation with the immobiliser module and thus prevent the engine from starting if there is a power loss.

Features of the OBD2 Power Saver lead:

The OBD2 power saver lead uses the vehicle's diagnostic socket as a connection to back-feed the electrical circuits rather than the conventional method of the cigar lighter. This is because (a) the cigar lighter (if used) can become covered with ash deposits and therefore fail to make a good circuit which would render the lead useless; (b) some manufacturers have fitted a diode to this circuit so it can't be back fed; and (c) most leads don't give any notification to the user that the vehicle's fuse is in good condition so you could plug in a power saver only to still lose all the important information and settings.

The OBD2 power saver lead has two user warning LEDs. When the lead is plugged into the diagnostic socket the yellow LED indicates that the vehicle's circuit is in good order. The lead can now be connected to a remote power source and when this connection is made the green LED confirms that the vehicle's battery can be disconnected.

The OBD2 power saver lead also incorporates a 5A mini automotive fuse and polarity protection.

Customer service

Preventing the loss of the radio pin code is excellent customer service and saves the embarrassment of having to explain this to the customer or the cost of replacing the code.
