Change PT batteries before IMLP?

With IMLP coming up this Sunday, I've suddenly become paranoid about the batteries in my LYC and PT hub.  They are showing no signs of any problems and no blinking is happening, but I'm wondering if I should change them.  Would you? 

If I do change them, will it alter the readings on my LYC in anyway so my watts will be off?  In other words, if my effort is showing 200 watts, will changing the batteries make that exact same effort show 210 watts?

Thanks-Keith

    Dont know about altering your watts but just to be on the safe side I put fresh batteries in my PT Hub about 2 weeks ago. Super ez and I am by no means mechanically inclined. Took about 5 minutes.

    I think you should change nothing that isn't definitively broken 5 days before a big race.

    If its been a while, I say change it. Just make sure you have enough time to test it out. My PT hub died in the middle of my RR before CDA. No data. If your wondering how, heres a video I did while back:

    I did the batteries in my PT hub 3 weeks ago, just in case....

     I also would not touch anything if they are working.  They blink low battery for a very long time.  I let them go for at least 10 days once without a problem.  Even if they started blinking low hub batt at teh start of the IM ride you would easily get through it.

    It is not just something going wrong during the change to consider.  The more times you open the hub you mess with the seals.  Only bad things can happen.  Deep breaths, not the time to get mental.

    I think you should be ok as Chris G says. Though my PT did die at CDA..... Of course I run a Garmin Edge 500 so got no warning.

    Keith,

    As has been stated if it's not flashing now you will have enough power to get you through and IM ride. 

    Any idea how many miles on the batteries?  Having stated the above if you are going to lose sleep over it then swap them out but do it now.

    Hmm. Do you only get a low batt warning on the LYC? I have the 310xt and I can't recall getting a warning. I am envious if so.

    For sure get a low batt warning on both the lyc and the joule. Not sure about my 310. Hardly ever use that as a power head. One more reason why everyone needs a Joule. The new cheaper one should be on everyone's Xmas list. On board NP is the only way to fly.
