Yashica TL-Electro Battery Fix

UPDATE: Silver oxide 357 1.55v batteries work much better instead of 675 zinc air batteries. You can shoot rolls continuously, and the meter appears to be accurate according to a light meter that I use. Happy shooting! I acquired a TL-Electro for cheap on eBay but couldn't use it due to the mercury battery ban. I used some 675 hearing aid batteries and a total of 9 washers to make it work along with my 3d printer.
