. 7. The Dry Charged batteries are:

• (1) Called flooded batterie

• 2) Electrolyte is addedcC

• 3)

  both 1 & 2

• 4) whose Life is calculated from the

  date of manufacture

the primary cell cannot be reacharged beacuse

• 1)during discharge chemical reaction takes place

• 2)option 1& this causes one of the metalplate being consumed
