Would it be possible to substitute a thin watch battery for a AA battery in a disposable camera because we found that the camera does not need the whole AA battery. Also, would it be possible to charge the flash by winding the same part used to advance the film? This is for a school project and if you have any other ideas on how to improve a disposable camera, it would really help. Thanks.Would a watch battery work in a disposable camera?If it works with a single AA battery, 1.5 volts, then it may work with any battery that puts out about 1.5 volts. But it won't last very long, and the flash recharge, which uses a lot of current, may not work with a weaker battery.
Some watch batteries put out 3 volts, be careful.
