Any lithium coin batter
My 2001 A4 1.8T remote batteries are Panasonic CR1620 3v.
The CR1620 battery is a lithium battery. This battery is small and is meant for watches and other devices that take small coin size batteries. It can be found online.
yes they are cr1620 lithium you can get them at Radio Shack
Although CR1616 and CR 1620 are only a few numbers apart, the CR1620 will probably be too big to place in something needing a CR1616. Therefore, many times they will not be compatible. I recommend that you buy the right size battery.
The two batteries may look the same but have slightly different power outputs. Interchanging them could damage the device by putting out to much or to little power.

As far as I have seen, the "CR" in the CR1620 battery number denotes a manganese dioxide lithium chemistry within the battery.
The CR1620 battery is used in watches and other electronic devices. Open the device, and look carefully at the back. A magnifying glass may be used as the numbers on small batteries are in very small print. Write the name of the device and the battery's number down on a piece of paper. Take it with you to an electronics or big box store. They are sold online by many companies, and are manufactured by different companies.
