I could do it by myself, but I don't know where to purchase this kind of batteries. Any help welcome and blessed! It's a CR2032, and it is possibly the single most common coin-cell battery on the planet. You can find them ANYWHERE. Radio Shack, Target, Sears, Walmart, Amazon, eBay, CVS Pharmacy, and other wretched hives of scum and villainy. Digi-Key sells them for $0.28.
