I'd say Rayovac came out high and low with 170 and 134 mAH, so you'd probably get variable results depending on the batch. What impresses me more is the general similarity across brands making price a more important factor. Good news to me since I had just ordered a year's supply (150) of iCellTech size 10 from Localbattery.com at a cost of 27 cents each, tax-included, using the save10percent discount code posted on this site. With free shipping and the test results in this string, I'd recommend a quick click on the "Hearing Aid Batteries" ad at the top right of the screen, order a zillion of whatever is cheapest, forget the hassle of trying to prolong battery life by replacing tabs or whatever else doesn't do much, and support our forum sponsor, localbattery.
