I took the sensor apart and almost got all the connectors off but on the last one I ripped off the little wire. AAhhhh. I tried now I will buy!!!!

I wish they made them to be replaced (easily) but that would cut into their profit$.

My sensor battery just died at the 515 mile point. Which I'd guess is about 77 hours or so....

I only had about 2 or 3 runs once the warning came on that the battery was low.

Dump that thing BobbyB! You'll like Garmin much better... P.S. John Denver says Hi!... Rocky Mountain Hi, that is.

 Mikey47 says:

Just got my first warning to replace mine. I'm at about 550 miles too, I guess it had a pretty good run, no pun intended.

 BobbyB says:

John Denver, RIP. Hey David! I just got a new sensor and hope to get a Garmin from Santa this year....can the Garmin blast out some Simon and Garfunkle "Bridge over Troubled Water" as a power song?....

Well i must be doing well as my sensor is only just running out and i have had it two years now. Time to buy another one. Do they sell them on ebay???

 fabricerun says:

My nike + now says "sensor battery low." Does this mean i have to buy a whole new nike + kit?

 Griffilicious says:

Just re read this thread and it looks like that's my only option. I don't mind spending the $20 for the new kit- I've had this one for over a year!

 Mightyman says:

Ive done 843 km with my sensor, i always put it into sleep mode after each run,so that the battery will last longer. Once the battery has died i will replace the battery in it.

 KMKMom says:

You don't have to replace the entire sport kit. You can just buy a replacement sensor for $19. It's a little better than buying the whole thing again.

My sensor died after 50 miles and only 4 months old. Thankfully it's covered by one year warranty and Apple replaced it. It was delivered to my door the next day (had to return the old one which they paid for shipping).

Hi guys'

I heard that you can replace the battery inside the nike sensor with a CR2032 battery and it costs only $5! It needs some technical skills but its worth I think

The link is: www.instructables.com/id/Replace-battery-in-Nike-receiver-for-under-5

BTW: One battery should last for approx. 1000 miles

external battery hack IS worth the hassle. the only problem with replacing the battery in the sensor is that the leads are spot welded to the battery. heating the battery up kills it. A better solution is to just tap into the wires on a dead battery unit, and connecting them to a minimal external 2032 battery holder, which can all be held by electrical tape. done, and you can replace the battery instead of the unit. takes a little time, but I'll spend 5 over 30 any day. I keep my HRM and cyclocomputer batteries fresh, why not a foot pod?

G'day everyone.

After my iPod warned me the sensor battery was getting low I found this forum. As my sensor is only about 6 months old and after reading Chris's comments on page 1 I decided to give it a go and see if the Apple store I got it from would replace the sensor under warranty. Any way, 10 minutes later I have a new sensor. The only problems it seems is that I now need to recalibrate for both run and walk, and my iPod now reports my summary as zero everything. By the time this ones battery runs low I should be out of warranty so replacing the battery looks like the best option.
