A precision watch battery manufactured by JCB. Suitable for analog and basic digital watches that have a continuous, low power consumption. This JCB 381/391 watch battery is 11.6mm in diameter and 2.1mm thick.
The JCB 381/391 is the perfect replacement for SR1120W/ AG8 batteries as they are the same dimension and voltage, but are constructed with a different chemistry (Silver Oxide).
Silver Oxide batteries have a very flat voltage profile, this means they keep producing 1.55v until they are exhausted unlike alkaline batteries which have a curved voltage profile, which means the voltage will steadily drop as the batteries discharge.
