Question
Dear Expert

Is it possible to build electrical circuit with alarms for indicating Battery Power consumed in electronic gadgets viz cameras, toys, watches, calculators etc ?.

For example :

Similar to alarm which we manually set in clocks, the electrical circuit designed will calculate the battery power consumed and when it is say 10% battery power remaining (low on battery, drained), alarms will buzz to the consumer as warning signals before 2-3 days in advance for the respective electronic gadgets. This process will be automated.

Awaiting your reply,

Thanks & Regards,
Prashant S Akerkar

Answer
I'm sure it's possible.
Whether it's economically practical -- ie, whether the added weight and expense of setting up this system will lead to increased sales to compensate -- is another question.

Since my specialty is physics, not electrical engineering, I'm completely unable to help you any further on this question.

Expertise

I can help with understanding physics that does not involve eggs. I will NOT help with academic or professional questions, which are NOT limited only to homework. Please do not waste your time by asking a question that comes out of ANY kind of academic, professional, or business matters.

Experience

Have been fascinated by physical laws ever since I learned, at age seven, that magnets work under water. My study continued through college and has not ceased even after I retired.
