Garmin Vivofit 2 Battery Replacement

A short time ago, my step tracker and watch went dead. It is a Vivofit 2 that is very plain and ordinary with no bells or whistles, as compared to other trackers. All this tracker does is time, date, steps, estimate of distance and calories burned. No heart rate or altimeter to tell you how many steps you’ve climbed, that said, this is also the first “smart” wearable that has lasted longer than 6 months. As far as watches go, this thing has lasted longer than any other.

This device, of which is primarily my watch, was supposed to last one year on two Lithium button cell batteries. It ended up lasting over two years which makes me start to believe that these button cell run times are all underestimated.

In preparation for this repair, I pulled out my card of CR2032 batteries thinking I could just pop in the batteries on hand. Once apart, however, an unpleasant surprise greated me beneath its dirty shell. I didn’t have the proper battery, the Vivofit 2 takes CR1632 batteries which are far more expensive. When I looked on the shelf of the store they turned out to be the most expensive batteries on the shelf at $4.99 each.

Before doing another thing with it, I cleaned the gasket and housing with rubbing alcohol because it was two years sitting on my arm and looked terribly gross. Popping out the batteries was easily accomplished with a flat-head screwdriver. Inserting the batteries, only required a bit of pressure to seat them properly. Four screws hold the body together. Upon putting the thing back together, the device immediately reactivated.

I let it do its thing of synchronizing with my mobile and that was it, the job was done and I have my watch back.

Out of curiosity, I wanted to see what voltage the old batteries were to know how much voltage was not enough voltage to power this wearable.

5.327 volts was the magic number. Instead of just tossing the batteries into the recycling, I decided to hang onto them. Who knows when I might come up with a use.

Final Thoughts

The batteries were a bit more than I wanted to spend but replacing the batteries was still cheaper than a new tracker or even a decent watch. Since the thing is mostly a watch and I don’t need anything fancy, this will do just fine for now. The total cost of this repair was $10.58. Still far less expensive than $109 for a replacement from Garmin.

Truly, I think trackers are kind of dumb but I like the metrics it gives me and there is something fun with the dumbness… like the competitions with friends on steps. This thing is a fine watch and I don’t care about status symbols so until this thing has some catastrophic failure, I’m not likely to upgrade.

Oh, one last thing, I have also created a short video on this repair and edited it with Kdenlive. My first foray into doing video with Kdenlive and so far, I like it very much… once I figured out what I was doing. The machine I used, Dell Latitude E6440 running openSUSE Tumbleweed. I didn’t have a single crash or lockup of the software.

If you happen to like this, great, if you don’t, that’s great too. It was a fine learning experience that I enjoyed.

  1. My Vivofit 2 is at least 7 years old, and the battery just died this week! I will gladly pay that price for batteries if I can even get another 5 years out of it!
