Di2 Battery Dies!
 

First of all, I know that Di2 has a dumb, little battery indicator light. But I guess I just never payed any attention to it.

So after five months, 1,716 miles and 85,810 vertical feet, it suddenly happened.

I was thirty miles away from home and all of a sudden I began to notice that my front derailleur wasn’t shifting properly. Instead of an effortless, one touch of a button, suddenly I had to push twice to get the front derailleur to move in any direction. I had to double tap it. How annoying. :innocent: Anyway, that’s when I first noticed the dreaded red light on the battery indicator.

I wasn’t sure how many more miles of shifting I could expect, but I thought I’d probably be able to get home. I was wrong.

About a mile later, the front derailleur totally stopped shifting. Luckily, I was in the small ring because I still had another 1000 feet of climbing to get home.

The good news is that the rear derailleur worked fine the entire time. The only real downside was some harsh cross-chaining on the way home.

Also, my garmin 500 battery died on this same trip. :notamused:

Um...how many rides did it take? Or are you saying it lasted 5 months on one charge?

Nice little dig at SRAM. I'm a SRAM fan but I still got a chuckle out of it, well done.

Yeah, that's how it tells you the battery's dying. Once the front derailleur stops shifting, all battery power goes towards the rear in an effort for you to get home.

It did its job. Three hours on the charger and that thing should be back to full capacity.

So . . . the battery didn't die. It wasn't even comatose. It went into that special mode reserved for people who go 5 months without a recharge and don't take the nano-second it takes to push the button and check the charge state.

All is well.

I really need to slow my roll...... Just say'n.

Mod edit :innocent:

rearry?

Correct.

But the OP knows this.

I didn't see any digs at SRAM in his post. I don't think the "double tap" reference had anything to do with SRAM.

You're really on a roll tonight. So it's not just me you like giving crap to. What made you so angry at the world?

Pretty sure it was, especially with the little whistling dude after the comment. If it wasn't intentional then it should have been. :D

I think is the part about the front changer not working correctly. Didn't one Sram user lose the TdF that way in 2010?

It lasted five months, 1,716 miles and 85,810 vertical feet


In retrospect, I obviously should have taken that extra nano second to check the charge.


Correct. And loling at you.


Maybe I needed to admit it in the OP.

Incorrect.

I am somewhat intrigued by Di2 but it's too much money for now.

A word to the wise: If you have nothing nice to say.....

It's never too late to start.

Oops... dang it! I almost never make those mistakes.

Do you want to kill BF? There would be like 2 threads left!

I'll let you kick it off since I have nothing bad to say. Wait, nevermind. Force magnesium levers break and Red titanium FDs suck. Otherwise, SRAM > any mechanical Shimano system.

seriously, charge the friggin battery and learn how your equipment works. It's not too much to ask

It's easy to forget. Di2 batteries really only need recharging once a month or so if you ride a ton, even less if you don't.

thats one fear I would have. I am forgetful person by nature and if I happen to be excited about my ride and off I go without remembering to have charged my bike.....I would be in trouble. To easy for me to make that mistake. I will rely on my manual shifting which hasn't failed me yet. plus I can save my money to buy other things I dont need!

I've had several mechanical brifter and cable failures over the years. It all breaks. Overall my impression is that in the long run a Di2/battery will prove to be quite reliable and maintenance free in comparison. Hell, my 7900 rear mechanical brifter failed after two years.

right but try reading a manual once in awhile and know what the product does when the battery fails. or just charge the battery
