TECHNIQUES FOR MANAGING CHANGE EFFECTIVELY. Managing change effectively requires moving the organization from its current state to a future desired state at minimal cost to the organization. Key steps in that process are: 1  Understanding the current state of the organization.
Batteries are made from a number of different materials. These materials include acid, lead, nickel, lithium, cadmium, alkaline, mercury and nickel metal hydride. When batteries are not properly disposed of the casing can disintegrate and the toxic chemicals within can leach into the surrounding environment.
In the charged condition the battery contains lead, lead peroxide and sulphuric acid. During discharge, i.e. the providing of electrical power, some of the lead peroxide and the lead will change to lead sulphate and water. The sulphuric acid is weakened by this reaction and its specific gravity falls.
