Nike + battery died again

Sunday, January 27th, 2008

My nike+ battery died again. I’m guessing this was a result of me trying to solder directly to the battery. I’m going to give it another shot by soldering to pieces of metal and attaching them to the battery. I’ll keep you posted when I get a chance to do this.

It did work great for the 1/2 marathon I ran, though.

1:48:15. Pretty good considering the amount of training that I did for the race.

This was a great race. Very well organized and the volunteers were great. The weather was perfect. Crowd support was lacking in certain areas, but that’s to be expected. I would definitely do this race again.

So I replaced my nike+ sensor battery

Not sure if this is a long term fix, but we’ll see. So far I have only walked with it. I’ll report back when I run with it.

Anyway, I looked it up online and I couldn’t find where anyone else had done this. My sensor was dead, so I used a razor blade to cut the case apart. The battery it uses is a pretty standard CR2032 3 volt watch battery. All I did was unsolder the connections from the old battery, remove the piezoelectric accelerometer from the top of the battery and then solder the wires to the new battery and glue the acceleromete to the top of the battery. I haven’t glued the case back together yet and my Ipod still reports that the sensor has a low battery, so we’ll see how long it lasts.

Here’s some links I found to what the guts of the sensor looks like:
