This 4/393 an unusual and increasingly hard to find silver oxide battery. The 4/393 silver-oxide battery is commonly used in remote alarm controls for VW and Audi alarm systems. The 4/393 is particularly widely used in later Volkswagen Logic immobilisers known as "Logic", "Conlog" or "Conlogic". These immobilisers were widely fitted to Audi, VW and Land Rover vehicles. When fitted to Land Rover vehicles it carries the Landrover partnumber STC8916.

The 4/393 is constructed from a stack of four silver oxide 393 button cells held with heat-shrink tubing. You will be able to see 393 or SR48 etched into the uppermost cell. If you prefer to 'do-it-yourself' you can order the constituent 393 cells here....

The 4/393 can sometimes be sourced from Volkswagen and Audi dealers but they have been known to charge over 20 each for them.

Earlier versions of the Volswagen Logic Immobiliser use the 5/392 silver oxide battery.

The 4/393 batteries have a shelf life of 5 + years, so why not buy two or more. Take advantage of our reduced price and make sure you are not left without a working keyfob remote next time your battery runs out.
