Maxell 303 SR44SW 5 Batteries

Dimensions: 11.6mm Diameter x 5.4mm Height

Do not use (inherently low performing) "LR" alkaline batteries in place of silver oxide in a timepiece: alkaline batteries have declining power output such as the LR 4 4, see below. 

The 303 is a long life silver oxide chemistry with non-declining power output; alkaline batteries of the same 1.5 voltage start at 1.5 and at the half life are at .8 volts, silver oxide start at 1.55 volts and maintain the voltage until expiring. 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 such as the LR 4 4. A watch with declining voltage may not be dependable.

Please keep these and all shiny child-attracting small batteries out of the reach of children; they are dangerous if swallowed. All batteries (you will benefit by learning properly how to handle your batteries) are dangerous and must be disposed of according to your local Solid Waste Department laws.
