This is the deluxe battery plus synchronizer kit. Battery life extended using internal Ultra-capacitor and regulator technology. This product, with its long battery life, is ideal for Broadcast Studio clocks as well as other SWCC clocks with synchronization capability.
If you own one of the smaller ATO style clocks which uses the "Horolovar" style replacement system, consider this unit. It will provide a steady, non-varying voltage over the full battery life, resulting in a stunning improvement in timekeeping. Replaceable AA Batteries included and installed!
