The Maxell 301 coin cell battery has 1.55V, a discharge current of 100mA, and a capacity of 110mAh. This coin cell has a flat discharge rate, so, it provides maximum voltage until the battery is drained and discharged. There is a high-energy density feature on here, which makes the battery able to pack in twice the energy of a comparable alkaline coin cell. This coin cell is best suited for low-drain devices like analogue watches. This battery is prevented from leaking through Maxell's leak-resistant processing technology.
This is why silver oxide batteries are always used in watches, insulin pumps and sniper scopes or mission critical situations. Never use alkaline batteries (they are not a wise choice for timepieces) for any device requiring a steady constant voltage. A watch with declining voltage will not be dependable.
