I would be putting the 2 x 1.2 Volt NICAD batteries in series to get the 2.4 Volts then I will regulate it Down to 1.5 Volts, I am driving a clock which needs 1.5 Volts. So I am going to need to charge the batteries at 2.4 Volts then regulate to 1.5 Volts. The low drop out voltage regulator Turn off the power source to the appliance containing your battery and remove the battery. Take a voltage reading with your voltmeter. Lithium-ion batteries may go into sleep mode if you drain the battery too much. For example if your battery is rated at 3.7 volts and the voltmeter only shows 1.5 V, it may be in sleep mode. Using a 5v source (USB) to charge a 3.7v battery inside and then using either buck or boost converter to produce the 1.5V/9V up to a specified current. The output voltage is constant (zero Output resistance) throughout the discharge cycle but suddenly switches off at the end of discharge. d. A ___-volt battery will increase the potential energy of 3 coulombs of charge by 18 joules. e. A ___-volt battery will increase the potential energy of 2 coulombs of charge by 3 joules. f. A 1.5-volt battery will increase the potential energy of ____ coulombs of charge by 0.75 joules. g. A 12-volt battery will increase the potential energy Therefore, each lamp will pull ~4.1 amps each per hour. For 9 lamps and 8 hours, that's a total of 295.2 amps pulled from a 12 volt battery source. My recommendation: 12 volts with at least 600 available Amp Hours. That's three 4D size batteries in parallel. .
