Pity, they state the price but conveniently forget to mention the mAh capacity! At the risk of going off topic, I’d guess that three parallel groups of three CR2025s in series would give about 450mAh, more if CR2032s would fit into the available space. Still, the price is perhaps understandable if good quality cells are being fitted. A high price to pay for originality though!
