PT SL Hub Battery Life?

I probably got close to 300 on my SL, but then they pooped out suddenly - in the middle of a long epic ride.
Changing is easy. Just do it now, cheap insurance.

"easy" if you are careful. The original batts seemd to have had a small amount of black glue holding them in. I took a small knife to cut through the glue. Also, be careful to not break the black tabs holding the batts in. I tried calling the 800 # listed on the batt holster and always got a busy signal. What other instrument or piece of equip (except Polar?) does one need to call a busy 800 number to change batteries? Rube Goldberg design????

That's exactly what I am worried about. I've got a 17.5 mile hillclimb TT on 9/17 and that'll be right in the 250-300 hour range. I think I'll just plan on a 250-hour replacement schedule. That's easy because it's almost exactly every 4 months. Thanks for the input. And, thanks for the heads up on the replacement issues. Cheers.

Mine didn't have the black glue. Maybe that was corrosion?

It's really easy to change them so I would recommend doing it sooner rather than later. I use a wrench with a towel to get the hub open so as not to damage the plastic cover. You only need the wrench to get it started. Takes about 5 minutes.

Did you apply grease to the O-rings as recommended? If so, what kind of grease did you use?

I just used regular bike grease (I can't remember what brand I have). I did not remove the o-ring as it says in the manual, just took off the cap, replaced the batteries, put a very small amount of grease on the o-ring (just enough to lubricate it so it doesn't bind when the cap goes back on), and put the cap back on. It's really really easy.

Great. Thanks for the input. I'll be doing this in a couple of weeks.

No, it was a small dab of black adhesive or silicone type material.
