What are the main difference between dry cell and lead storage cell?

Question

size

use

convenience

quantity of electricity

try to write the difference on the basis of above.

Answer 1

Size:  dry cells are compact & dense as they are 'dry'.  lead storage cells require fluid, an acid - so are much more bulkier to compensate for the fluid requirements.  

Use: also equates to availability / price.  The extreme majority of automotive batteries are lead because they are cheap, and sizing has never been a big problem with combustion engine compartments.  Dry cells are found in portable electronics due to their compactness & price, but have a low run-time.  

Convenience: dry cell for the win; zero maintenance and highly available.  Lead cells are bulky and heavy, hazardous and can be explosive.

quantity of electricity: the new dry cells / lithium ion - have amazing run time and extreme rechargability, but still cannot outpace lead acid.  Deep-cycle marine batteries that are designed to put a pro bass fisher on a lake for 14 hours non-stop are lead acid; you can't do that with dry cell...yet.
