Battery acid. A very strong acid that can give it's power to something I think that potatoes have a certain acid in them which is why they can make clocks go but yeah. Battery acid. It's stronger than whatever potatoes have in them.
With Batteries
In addition to analog clocks, Masterclock also sell digital clocks, advanced timer servers, and clock controllers. You can also find PC software, programmable bell ringers, and power supplies.

Only on clocks.
Timers, oscillators, square wave generator, power supply clocks, system clocks...you name it.

Electric clocks will, by definition, last much longer, or until your mains power fails.
Potato Power is making a battery from potatoes.
