Just got my new 530G. Materials supplied with the pump state that you should not use lithium batteries. I have always used long lasting lithium batteries in my other pumps. Does anyone know why they should not be used in the 530G?

Hey so you need to be using alkaline batteries with your Minimed pumps. Lithium is only to be used in animas pumps. DONT TELL MEDTRONIC THAT YOU USED LITHIUM BATTERIES in your Minimed or they will void your warranty. It happened to my neighbor! So you need to use alkaline in your Minimed! Lithiums in Minimed can cause the pump to drain the pump and bolus you the whole reservoir.

Let us know what you decide!

Cannot help you there. Also sys we cannot go through airport scanner anymore?

Lithium batteries discharge in a different way than alkaline batteries. Your 'low battery' alarm will not work with lithium batteries. You would be taking a chance that your pump will just stop working all at once with no warning. I don't think it's worth taking that chance. Buy the batteries on sale at Walmart or Target and change them when your low battery alarm comes on!

Thanks. That makes sense. Although the lithium batteries last so much longer, there is no alarm when they run dry.

i wouldn't risk it. a damaged or flawed lithium battery can catch fire.

i believe they also recommend energizer batteries over duracell, as energizer constructs their batteries with two smaller cells inside the casing. the reasoning is that if one cell fails the pump wont stop completely.

Actually, it is the Energizer Lithium Batteries I have been using The last about four times as long as the alkaline max. I have been using them for five years without any problems, except that the low battery alarm does not sound.

I can't wait till I get mine. I should have it in two weeks! I am so excited!

use aaa batteries with the extra description LR03.
