re: Battery replacement for a Starkey Surflink Remote:
If you reside in the USA when it comes time to replace your battery in your Starkey Surflink Remote it will cost you almost 1/2 the cost of purchasing a new one!
Even though the actual battery a Lithium CF234044 only cost $1.37, it is currently not available for purchase in the USA.
Starkey has it controlled so that the entire unit must be sent back to their factory to change the battery.
So far, the best price I could find to have this battery replaced is $130. [This price quote was via a third party repair center]
For years various Audis have been pushing me to purchase this remote, and now I wish they would have told me the “hidden costs” of replacing the battery.
