Vivofit 4 poor replacement battery life

The original batteries in my Vivofit 4 ran out after 8 months. I have used Renata and Maxell SR43 silver oxide (not alkaline) batteries since then, and none have lasted more than a month (the latest set lasted only 17 days). I have the syncing set to the lowest frequency, and sync no more than once per week. Any ideas why my Vivofit is eating batteries?

I will stop using it if this continues - even in a big city I cannot buy these batteries locally. Why didn't Garmin figure out how to fit much easier-to-find SR44 batteries?

Hi there! The device should not be quitting on you this often even with new batteries. I would like to help you get this resolved. Are you in the US or CAD by chance?

I am in Canada. I measured the battery voltage each time it quit, and each battery was less than 1 V, so the batteries really were used up. They measured 1.57 V when new. When I replaced the batteries a few days ago I made sure to carefully clean the gasket - no signs of moisture inside. And I also cleaned the battery contacts, although they looked good as well.
