Send it to SRM to have the battery replaced?

Don't know how I missed your reply. I thought you were talking about going to SRM or Quarq. I have thought about the wheel upgrade option, but I would need to get both hubs upgraded, and either start remembering to bring the head unit home with me every day, or get a 2nd head unit too. (I leave one bike at the office, and one at home for trainer/commute/weekend duty). Both hubs are probably ready for service anyway (though I could do the bearings myself for a lot less).

I probably just need to squeeze such an upgrade into the budget at some point. It's not that big of a deal, but you're right about me hating EOL of some items.

i would call SRM USA and tell them the issue. they can replace the battery (or you can do so if you have some basic soldering skills), or i suspect they might make you a very attractive deal on a pc7 if that is of interest. the pc8 is coming out soon.

Is it going to have an interactive GPS in it? From what I have heard, it will not.

sorry--missed this. i don't believe it will have mapping, only recorded gps as an added data point.

Of course it's hard to make out ceramic bearings or see guys getting massaged off camera.

And granted that while everything would make it appear that Quarq is a sponsor, they didn't publish the specific terms of their financial and promotional agreement on the website, so for all we know the guy from Omega is just throwing Mrs. Quarq a bone (so to speak) for services rendered. I hear they have great "customer service" (wink wink nudge nudge say no more)

Damn quarq just dies when the battery goes out..no warning nothing. Which is fine because I have a backup battery and popped it right in. Problem is even though I put the cap on TIGHT via hand on the road it doesen't look like it went in all the way as I had power for about 10 minutes before it went out again. Had to go home and crank down on the cap to get it to touch the contact. Might put a piece of foam in there today if I still have issues so that it can reach contact as I have a crit tonight and want the data.

Assuming that is the actually problem

hey, chemist--
the contacts on that battery cover can be a problem with a quarq. i'm also assuming you're using good batteries. (i ask only because one time i bought a lot of 25 or 50 batteries on amazon, and when i tested with a multimeter many of them reported low voltage....with even a minor dip (a tenth of a volt), i've found the quarq can cut out.)

one more thing: if you handle those small coin cells with your fingers it is very easy to get oil on them. in the quarq, this can cause power to drain VERY quickly. if at all possible, use gloves/a tissue/whatever to avoid getting any oils on the cell.

unfortunately the communication of battery status between quarq and head unit can be very spotty. good on ya for having the spare battery!

when the battery starts to head south, sometimes the prior data is suspect.

is there a respectable garmin alternative yet? PC8 or whatnot?

I'm a little tired of losing rides because I hit "stop" and then "save" too quickly. ****ing ay.

Thanks Teton! I am going to go ahead and clean it out today with some chemwipes. Before and after manual zeros have been good up until yesterday. Jumped about 20 units and I knew something was up but thought it might have been weather as it was particularly warm then 10 minutes later no power, go figure.

Thanks

sounds like you are both on top of things and prepared. that diligence pays off and even if your meter does have an issue you will minimize data problems and/or loss.

oils on the cell (even from handling with 'clean' hands) can reduce battery life in a quarq from 400 to just 50 hours, in my experience. it seems to interfere with the 'sleep' detection.

DC Rainmaker also liked the Cyclo 505:
Mio adds wireless Shimano Di2 integration, ANT+ trainer control, and more to Cyclo bike units | DC Rainmaker

I'd be very happy to see a credible alternative to the Garmin Edge series.

what head unit? what should the offset be?

I have garmin edge 500. offset is almost with my SRM is always 589 or 590. this looks weird to me because I also have a quarq riken (on my road bike) and it's offset is between -40 and 40 depending on whether i'm inside or outside, but is usually around 0.

offset for SRM is the correction applied to get things back to zero. There's always going to be some tension on the crank, thus generating some torque, and the offset (absolute value) is applied to "zero" the unit.

I'm using a Garmin Edge 500, and the offset is usually between 370 and 410; within a particular ride, rarely drifts 4-5 unit (2.5 watts at 100 rpm) unless if i expose it to the sun for a minute, causing things to expand, etc.

i think one of the seals may have gone fubar when we had that driving storm in mid April. Usually i just let the bike air-dry in my apartment. that day i got lazy and put it in my trunk. Or it may be due to riding it on my commute through all but the worst days in the winter.

send it in at this point. they will take care of you.

on an SRM, a 40 unit variation within a ride is big. i can often go from an uninsulated garage in spring (35-40F) to 70-80F in the sun and seen no variation.

sunlight shouldn't cause problems.

some other meters claim that a 50 unit variation is normal, but on an SRM it is a warning sign to me.

garmin's decision to not continuously record data is annoying, and i think the way they choose to display data while not recording does not help in sometimes tricking people. one shouldn't have to hit start/stop.

i was a product tester for garmin for a decade and this was always a bother. i still own garmin units (they're good for updating slope on a power meter) but never ride with them.

some say losing data (the odd corrupted file plus the possibility of having it simply not record) is not a problem, but to me never dropping data is high on the list of requirements for a head unit.

pc8 is around the corner for those who want gps (record only).

Chappy, I know it sucks to lose your power meter in the middle of the season but you should send it off to CO now. If it can't be fixed they'll set you up with an upgrade deal. Think about setting yourself up with a backup power meter like an older Powertap. Mine has saved my butt countless times.

The offset on my SRM varies between 429 and 440. Between the cool basement and a hot car, in that range. I think this is one if the main differentiators between an SRM and any Quarq I've owned. Better temperature compensation.

My Garmin 800 is starting to show signs of age. The lap button is getting flaky. Sometimes I have to push it more than once to start the lap or stop the interval. If I don't look down to see the lap box and it keeps running, introducing zeroes, I get yelled at, and for good reason. Eliminating junk data is a waste of time. I have a few options. Send it to Garmin and pay for a refurb, cost unknown. Buy a clean used PCVII and give up nav and multiple data screens, around $300. Bend over sharply and pony up for an 810, in the $600 range. Give up nav and some data fields and downgrade to the 510 or 500, between $200-$300. I don't know what to do at this point.
