I heard from a MiniMed 512 user that the battery life they get is 2 or 3 days to 1 week. My average
with the 511 has been 1 month per battery, and I am running pretty high basals, using the backlight
often, and using the vibrate feature, which should all take more battery life. I spoke with MiniMed
and was told that they only expect battery life of 1 week on the 511 and 512. I was wondering what
you all get for your battery life. Because I am considering upgrade to the 512, I am concerned that
my battery changing may go from once a month to once a week, which seems a little excessive to me.
Does anyone know if the 512 uses more battery power, perhaps because of the Link to the BD meter?
Now the rant! I am a little appalled that MiniMed would change from a battery 'system' that was
working well to this. With the 357 batteries, I could get at least a month, if not 2 or 3, of use.
MiniMed, of course, has an answer to this, claiming that the batteries used in the 511 and 512 are
cheaper. At only $9 for 3 of the 357's, and only having to change them once every month or two, I
think this was the easier option. Also, if an AAA battery costs $1, then you are still spending $8
every two months anyway.
