HP41c battery pack cells, New NiMH (FS)
Hi, I have a limited number of 1/3AAA solder tab NiMH cells for sale, they are 170mAh, so about twice the capacity of the originals. Physically, these are marginally smaller than the original 1/2N cells, so there should be no problem fitting them in the holder. Price is $30 for four cells including postage anywhere in the world. Thanks, John
