    Powertap min voltage?

    Anyone know what the min voltage requirement is for the Powertap (later SL+ for me) is for the PT to run?

    I had a set of 357/303 Energizers in it. The batteries had been run for 151 hrs and read 1.3v each on my meter. Everything was still working, but I was worried that they'd die soon, so I replaced them.

    I put in a new set of EXP76 batteries. Fresh out of the pack, they had 1.6v each. Not a big deal at all to replace them, but I'm just curious if those old batteries were half done, almost done, etc.

    Thanks,
    Bob

    I've experienced weirdness with my SL+ at the 150-200hr mark and had to replace batteries at that point the last two times.

    I measured 1.21V the time my batteries got low enough for the Garmin to not detect the wheel (sl+). I now replace the batteries as soon as I detect some weirdness.
