A Garmin doesn't last forever

My current Garmin

I've posted many pics of my running partner, my Garmin Forerunner 205, which I also refer to as Garmie.
Lately, I've been getting a low battery warning after an hour and a half or so.  So far, she hasn't died during a run.  My longest run was Saturday at 2 hrs and 27 mins.  My runs are going to keep getting longer and then, of course, the marathon is going to require around 4 hours and 30 minutes. My suspicion is that the battery is wearing out.
Tonight was my lucky night, I guess!  I didn't know that a Garmin rep would be at running group tonight!  I got to ask her about my shortening battery life and she confirmed what I was wondering - that it is a sign that the battery is wearing out.  It hasn't even been three years since I got her.  The rep said the average life is 4 years.  I got this one in October, 2010.  My first Garmin, a Forerunner 201, lasted 6 years.

My first Garmin, the 201

The Garmin rep had all the current models with her and I got to try them on and push all the buttons.  The one thing that I really want to be able to do is to change the lap distance like I do when I'm pacing.  99.9% of the time all I want is mile splits.  When I pace, I change it to quarter mile splits.  I would not be able to do that with the Garmin 10 which is too bad because it comes in pink!  I think I am going to go with the Garmin 210; it's so much smaller and thinner than the one I have now.  The buttons are in different places but they are the same buttons that my 205 has so I know what each does; I just have to learn the different placement.  The Garmin model that is the latest version of my current one is the 910XT.  It's just like the one I have now except much thinner.  It's also very expensive.


Soooo, within the next couple weeks or so, I expect to be making an unexpected purchase that I didn't think I'd have to make for at least another year or two.
