After flashing its digits to warn me about its low battery for months, my
Nike watch finally died yesterday. In the past I've not had very good luck
getting new batteries put into sports watches, so this time I resolved to
try it myself. Amazingly, the patient appears to have survived. Here's what
I learned: The bolts on the back panel come off quite easily with a small
screwdriver. The battery is held in by a thin metal strap which I wasn't able
to figure out how to remove, but I was able pry the battery out from under it
and slide the new one in the same way. You just have to be careful not to
scrape the batteries across the circuit board. There was a sticky label on
the old battery that said something about having to short circuit some spring
to some terminal, but that didn't seem to be necessary.
If you do this, beware that the watch won't be waterproof anymore because you
break a seal when you open up the back.
At $2.50 for a new lithium battery vs $60 for a new watch it's definitely
worth a try.
