12 volts
Voltage is how much power the batteries have. I think....
500
Energizer recharable batteries offer the best charge the longest.
36 volts
Stabeto online store is the best place to buy alkaline batteries in bulk quantity. they have energizer, duracell, panosinic collection at the best price in market. they have free delivery options too. Energizer LR44 button batteries , so much more are available
AA zinc and alkaline batteries normally provide 1.5 Volts when they are new. The voltage will drop as the battery discharges. Rechargeable batteries using NiCad or NiMH technology deliver 1.2 Volts when fully charged. Again, the voltage will drop as they discharge. It is this small voltage difference that can make rechargeable batteries less effective for some voltage sensitive applications,
Wired in parallel you will have 1.5 volts just like you have 1 battery. Wired in series you will have 4.5 volts. In parellel the amperage will triple but the volts stay the same.
9 volts
the answer is 36 volts
3 disposable type (1.5v) batteries would get you to 4.5 volts, and 4 rechargeable (1.2v) type batteries would get you up to 4.8 volts. As far as the size... You can get 4.8 volts from any four 1.5 volt batteries. The batteries will power the load longer, though, if they are bigger. 4 rechargeable 'D' cells and 4 rechargeable 'AAA' cells will both run a 4.8v motor, but the 'D' cells will do it for much longer. Estimate how long the motor is to be used, or how much load will be on the motor, and make your best guess as to the battery used... Normally, you wouldn't use 'AAA' or even 'AA' cells for a motor actually doing something. I would probably go with 'D's.
9 volts.
