I'm currently reading "Sinclair and the 'Sunrise' Technology", which has a section on the calculator.
They initially had problems with battery life, but took advantage of the fact that they could strobe power to the LEDs and chips without completely compromising functionality to reduce the power consumption by a factor of 100. That allowed them to use hearing-aid batteries.
