Mini Generator

Hello,

Not all appliances will work on DC (what the batteries deliver).
A light bulb will work, but a television or radio or something with an AC motor in it will not work.

Hello,

A fluorescent light bulb will probably work on AC as there is a ballast in the housing.
It will probably NOT work on DC from the batteries.

Does the generator produce AC or DC?
If it does generate AC it can NOT be connected to the batteries directly.

Old WWII submarine circuits used DC florescent lights, but they were highly inefficient since they used resistors (which got very hot) instead of ballasts.

If light is what your after use LEDs and a few batteries.

If you need AC, buy an inverter with several deep discharge lead acid batteries (marine, not automotive), it is a lot cheaper than making something from scratch.

So, I might use 96 batteries to fully operate my generator, right?

Do you mean that you want to use the batteries to substitute for the generator, when it is idle?

Lightfire said:

Does 96 pieces of 2.5 batteries can operate an appliances which needs 220 to 240 voltage. I think yes, since 96 pieces of 2.5 batteries is equal to 240 (if the battery is connected each other)

It depends on the current draw. At no draw, you'll have no trouble hitting whatever voltage you want. But every cell you add will also add resistance, which will translate to lower voltage under load. That resistance will likely prevent you from accomplishing what you want. The total power you can produce will be very limited, unless you also add batteries in parallel.

Lightfire said:

If it can be, how many hours it can operate and how many hours it will recharge again? Please take note that my batteries is not rechargeable batteries.

If your batteries are not rechargeable, you cannot recharge them. Period.

Lightfire said:

May I ask also, if the bulb from the car is about 12 voltage?]

Usually, yes.

I don't know. The batteries that I am planning to make as a generator is a normal battery only which is have a code phrase like "Double A, Triple A, and so on".

Penlight batteries as a supply?

First of all they really only come as 1.5V

Secondly, they have a very limited amount of amp-hour capacity, matter of fact it's measured in mAh.

If you managed to hook 160 of them in series you might be able to run a 240V 100W incandescent light bulb for a few hours maximum.
If it's something that requires very little current, and can run on DC, then you'll need to know the data on the batteries and the device being driven.

BTW: Generators create DC electricity from a mechanical input such as a gasoline engine, alternators do the same thing but output AC.
