My Nemesis does not work well with flat-top batteries. I am planning to get another, and have only two button-tops. I have noticed these: $1.15 Round Super Strong Rare-Earth Neodymium NIB Magnets (10-Pack) 10-pack - 5mm*1.5mm / perfect for use on batteries at FastTech - Worldwide Free Shipping Would they work so that I do not have to buy more batteries for Nemeses?
