ABSTRACT
The practical importance of a battery charger in today world cannot be over emphasized. This is so as those batteries accumulators are immensely needed by out auto mobile and in science laboratories.
This thesis describes the methodical approach to the design and construction of any battery charger. However the procedure fro developed cover the construction of battery charger for battery sizes ranging from 6 voltage to 24volatge (heavy duty) batteries.
The prototype of a battery charger for these ranges of batteries has been implemented following the methodical approach as outlined in this thesis and its operational test results are quite satisfactory. adequate care has been taken in the design and construction to ensure that the resultant battery charger are both reliable and easy to use.
