The reason it charges low voltage batteries is because a LED does not require much voltage to produce light. The lower the rated voltage of the battery that has to be recharged, the less work the human has to do in order to recharge it. The design should be efficient and cost effective to provide a means of charging batteries to those who may not be able to afford electricity<sup class=\"noprint\">[[Wikipedia:Electricity|W]]</sup> and or those who are in areas where electricity is unavailable. The design should also be made of materials that are easily available.","Page image":"File:The Battery Recharger.JPG","Page is part of":"MECH425 Engineering for Sustainable Development","Page keywords":"human power, battery charger, led, energy generation, bicycle rim, DC motor, belt, Energy, electricity generation, battery, Appropriate technology","Page language":"en","Page license":"CC-BY-SA-3.0","Page title":"How to Build a Mechanically Powered Battery Charger for LED Lighting","Page views":"13717","Page year":"Friday, 01-Jan-10 00:00:00 UTC","Project authors":"User:J.
