Question about Medtronic MiniMed 630G

Hello everyone,
I am Denys Myakota and I am using insulin pump Medtronic MiniMed 630G. Could everyone answer me please, how often I need to replace battery in Medtronic MiniMed 630G? Does anybody know how faster Medtronic MiniMed runs out of battery?

Thank you,


Hi @Denys! If someone else doesn’t come along with the answer in the meanwhile, I’m putting a shoutout to @Rphil2, as he should be able to help you.


I only used the 630g for about 5 months a few years ago. But I can say the 670g was getting between 2 wks and 10 days on a single battery. This depends on how far you are willing to let it go down. I tend to change mine within a day or so if getting to yellow.

Using the sensor will deplete the battery quicker so if you are not using the battery you will get greater use.

I have heard of non sensor users getting 3-4 weeks but again I think that depends how far you are willing to let it go into yellow. (Running out of power is one of my obsessions so I change quickly, hey we all have our thing).

If you are getting less than 10 days in a new battery I would call Medtronic. They may advise trying a different battery. I use energizer alkaline batteries.

This is the purchase option I use fir batteries.

Best rick.

( I will add my disclaimer when I get to a computer. Suffice it to say that I am a medtronic ambassador - they gave me a cool shirt but I don’t get paid - my thoughts are my own - I use medtronic products but like you I pay full price( blah blah blah
