Hello moms

Anyone use rechargeable batteries with their pump while out of the house? I am "on the go" quite often when I am working and so far have had access to a outlet.. but it would be so much easier if I could just use batteries in my pump instead.. but am hesitant to make the plunge to buy the batteries b/c they are not cheap and i'm not sure how long a charge would last me? I try to pump 3 times during the 10-11 hours i am out of the house.. and usually pump for about 10 minutes each time..

for those of you who have used the ameda pump with this kind of set up what kind of batteries did you use, how long did the batteries last, and what was your overall set up? links to actual products would be greatly appreciated!!

also if anyone used rechargeable batteries with a non-ameda pump, pls feel free to share as I think it would be a similar experience..

p.s. i am pretty much set/stuck with my ameda and very happy with it otherwise so i'm not looking to purchase any new pumps.

TIA!
