Medtronic MiniMed 640G System

I suspect you will find the pump can not use rechargeable batteries. So check this out. before you use them as you could damage your pump and the warranty will be invalid.

 

Rechargeable AA batteries can be used with the 640G.

 

I was told by the Medtronic Rep that I couldn't use rechargeable batteries in my 640 g.My NHS trust supply my batteries.

 

The user guide says you can use a fully charged AA NiMH (HR6) nickel-metal hydride rechargeable battery.

I know we couldn't use rechargeables with the Veo but they seem to have changed it for the 640G.

 

I get my batteries supplied by medtronic.

 

Same here, but why they don't supply decent lithium like Animas I don't know.
Lithium last at least twice as long

 

I refuse to have Animas supply the batteries for my pump. They charge £8 for two batteries. I picked up 10 batteries for £13.95 and would rather pay that than have my ccg ripped off to that amount.

 

I think my 640G was also supplied with two batteries but they were the same as the ones Medtronic supply as a replacement. Standard AA energiser batteries.
Having a look back over time (6 months now) I can see the 1st battery lasted just 12 days obviously as I was playing with the dame thing so much getting used to it. The 2nd and 3rd batteries although slightly better only achieved 22 and 18 days but guess that's because at that time I was also using the Enlight sensors. Having stopped using the sensors (self funding so cant afford it) I have to say that the next 4 batteries after the sensors lasted 26, 24, 21, and 26 days, with the current one on its 14th day so in total I have used 8 batteries in 5.5 months, which no doubt will make 8 in 6 months if this one last another 10 days.
Certainly is you average out the last 4 batteries it look like the standard AA Medtronic supplied batteries will last about 24/25 days each for me so will need about 15 to get me though a full year which I don't thinks really that bad, Yes my old Veo lasted far longer than that but hey it did not have as many bells and whistles at the new 640G has.

As to cost of the batteries I have no idea as they are funded by the NHS like all of the Medtroinic spares and the price doesn't show up when ordered on-line, but no doubt as @CarbsRok stated above I bet its way more than if we were to purchase them.

Good luck in 3 days

 

I wish you all the.best of luck

 

I have the price list from Animas so can see exactly how much my CCG is charged. Hence why I now refuse point blank to order batteries from them.

 

You might want to take a notebook with you as they tell you lots of information and fast. Also take plenty to drink and maybe some snacks as you can be there for hours.
Good luck!

 

i can't order via medtronic website as the prices are all up there, even though i keep telling them they are yet to sort my account, or can't! i don't know, anyway they charge £5 for 4 AA energiser batteries for the 640g

 

Brilliant news Spicey, very good levels
