I need a circuit built into a very compact casing. It needs to operate for short periods on time on 12, 18, or 24 Volts, depending on how initial design testing goes.
Because of the small space, I need to use Lithium coin cells in place of the 12V "security/alarm" cells I typically use. Before I do anything, I need to know the max number of these button cells I can link in series before something dangerous happens. Anyone have an idea of what the upper limit is?
Specifically, these are CR1220...
Voltage: 3V
Continuous Drain: 0.1mA
As an alternative, I could take some other battery type.
