BU022 - This battery is a direct replacement for the original 1.5v Bulle battery No23 which is no longer available. The size is slightly shorter than the No23 and is designed to fit the column of the tall “A” movement clocks It will also fit many other Bulle clocks but NOT a clockette (height includes terminals).Please be aware of the measurements of this battery and double check the battery compartment of your clock to be sure it will fit.. The terminals are 3 mm screw studs with insulated caps to protect the terminals from shorting when used in the model “A” column  The housing encloses a small  regulator circuit based on the Maxim Max667 chip, and has a  potentiometer allowing the battery voltage to be set anywhere from 1.25v to 3.0v providing a stable regulated supply to the clock. The maximum current is 250ma which is more than enough for the Bulle clock. The unit is supplied with a holder for standard replaceable “AA” batteries. The benefit of adding the regulator circuit to the battery means that the voltage will remain constant throughout the life of the batteries.
