PT hub batteryl life??

How long does the battery last in the PT hub?  I got mine in February, and have a race coming up in a 10 days.  Don't want to get half way through and lose my PT.  Are the batteries pretty easy to find?  Thanks

    Easy to find they are standart watch type batteries. Has it been acting up at all? I know I have mine for about a year now and no problem but I will change them soon just to be sure.

     Mine have lasted a year to a year and a half.

    Bob, you'll see a flashing transmission icon when you're getting low. It'll flash for several hours, so even if you see it during the race you should be okay.

    Mine last many months.  But many in here replace them like they replace their tires, get bike tuned up, etc. before their A race.  Takes literally 10 minutes and $7 for the batteries.  Never hurts to be safe and have piece of mind.

    Good to replace for peace of mind. Also depending on the hub and if you have the right tool you will want to do it without any stress.

    Bob - I think the manual says 300 hours of riding on the hub. I replaced mine last summer and they worked fine through race day. But agree it is literally a 10 minute change. Read the manual for type of battery though. I think some, eg lithium, last longer than others with the hub. Also, do this at home before you get to the race site. You'd be suprised how hard it is to find batteries the day before a race!

           ditto on new batteries,tubes, etc.  I went down to Knoxsville Tn. in may for the Rev3 1/2 IM and took the bike out to check things Sat. for the Sunday race and no power meter.  On top of that, I didn't have the adator to get the hub off, etc so raced with my Garmin 305 but with no power.  Train all year on power and geeked up to race with it and it dies the day before a big race so I won't do that again.  I would change them before a race.  It's not worth chancing at $3-4 for batteries.

    Only thing I would note is to change the batteries days ahead of time (not the day before the race) so you can do some bike sessions to make sure everything works fine.  That way if there are issues you have time to call Saris for some of their killer customer support.

    Have a great race, Bob!

    The replies you've gotten are consistent with my (2-year) experience. It's the wrong time of year, but the first symptom I got when the batteries were dying was that the transmission was fine while the bike was warm from being inside, but as it got cold from being outside (in the 40s as I recall), I would suddenly lose signal. Took me a couple of cold spring rides to figure out what the correlation was!
