Electrical Engineering/Rechargeable or Non rechargeable batteries Thumb Rule.


QUESTION: Dear Prof Cleggsan

What is the Thumb Rule for installing Rechargeable or Non Rechargeable Batteries in Electronic Devices?.


ANSWER: There is no set rule-of-thumb.  It depends on the design and intent of the product. There are some products which must have rechargeable battery installed; there are others that will not accept recharging functionality because of voltage differences. While there are other devices in which you can use either type of battery so long as voltage and mounting size is consistent.

For smartphones, for example, the specific rechargeable battery must be installed.  For flashlight they will usually accept either kind.  For pocket pager or wireless phone it usually requires a recharging battery; but again there are many differences between products.

Recharging batteries are more expensive to the consumer but can be charged many times and over long time may be much less expensive.  There are great differences in quality of charge among non recharging batteries.  Some batteries will last twice as long as another with similar specifications.

QUESTION: Dear Prof Cleggsan


Is it possible to design a Electronic product which will work on both Rechargeable as well as Non rechargeable batteries?.
2 Mostly the toys in the market are having Rechargeable or Non Rechargeable Batteries?.


Yes, of course.  Most toys and other apparatus might work on C, D, aa or aaa size cells.  There are recharge equivalent for each of these battery sizes that can be used in the same mounting slots.  And other sizes as well.  

There are other battery options.

The above is a good overview of popular batteries that you might find common place in the world markets.
