I believe medtronic was not liking them so much on the older ones because when the end came it came quickly - not the 24 hours you have on the alkalines - they called it half life or something
However I am 99 percent sure they recommend them for the newer pumps
An easy solution would be to swap it out every week or ten days or whatever regardless of the level the pump states
I like that solution of swapping them out every week. I wish my Tandem used replaceable batteries. That’s the only complaint I have about the pump. I’m an old school Medtronic user, I’m used to swapping batteries out of pumps.
You might want to be cautious about Lithium batteries…just in case. Never know. Best if you can, "Purchase batteries from a reputable manufacturer or supplier. "
I used the regular lithium in my 530g for years. I never had an issue with them other than the battery level meter. The pump didn’t generate any extra heat from the lithium battery either.
I won’t be able to comment on the lithiums that I just bought for some time, because I’ve got one of the regular Energizers in the pump now, so it will be about 3 weeks before I’ll try out a Lithium. I’ll report back when the first lithium dies.
Dave, I have a 630G (very similar pump), am not using Minimed’s CGM system, and I get 28-31 days on each Duracell Quantum battery (which cost a bit more than the Duracell regular alkaline batteries). I’ve never had a battery go less than 28 days (and yes, I keep track of each one!).
For me, the good news is that AA batteries are so easy to find. I always have a spare battery just in case.
Hope this helps!

Dave44, I have the 670g with the sensors running in auto-mode,and I use the lithium battery’s. i get 6+ weeks per battery, and run about 92%+ time in auto mode. I have found no issue, I usually stock up on batteries around various holidays, from Walmart, buying the larger packs. There is some juice left in them when the Medtronic alarm sounds, I just keep the batteries and use the remaining power in my kid’s xbox controller.
I use a CGM and check my daily history every day and my 7 day history and 30 day history, which take a number of seconds to load, several times a week. I believe this is why my lithium Energizer batteries only last 12 days.
I am currently using regular Duracell batteries. I buy a pack of 40 for about $15 or about 38 cents each at Costco. They last about 10 days which, for me, comes out to be 3.8 cents a day.
