Batteries

100

numbers of galvanic cells arranged in series or parallel which convert chemical energy into electrical energy through redox reaction 

what are batteries

200

cells which has no reversible reactions and which can not be recharged 

primary batteries 

300

cells which has reversible reactions and which can  be recharged

secondary batteries 

Electro chemistry
