My Avocet 35 battery finally died. It has an unmarked battery, what kind of battery is used as a replacement?

Also, I need to replace the battery in the Polar s720i. According to the manual, it is a CR2354. I can't find it in supermarkets/pharmacies, anyone know of a source?

the avocet battery is a #357 silver oxide, 1.5 volt.. You can find those at radio shack or online with avocet

Forget trying to find the polar battery at a watch shop, they will find something close but not quite the battery.. I buy mine on ebay and keep 1 extra around..

Polar frowns on people changing their own batteries. They want you to send them in where they do a pressure test to test the water resistance of the seal.

I've changed my batteries on my 720i and have never had problems.
