Rechargeable led light power system Answered

, any ideas on how i can make this unit rechargeable? and by that i mean to where u plug a cord into the unit and it charges the internal battery for the battery is not removable in the unit so its kind of same idea as charging your cell phone. below is a drawing of the unit.

Lets be clear, I did not design this LED circuit..

I do not know what LEDs are used, or resistor values used, or what battery (looks 9V) used..

I have drawn where to charge the battery when the switch is OFF and provided a charger schematic that you can tailor to whatever battery you choose..

You must decide on the current and voltage your battery needs for charging..

Be sure to click on the schematic pic, to see the entire image !!

Hope this answers your question :-)

thx that seems not to hard! im using 3 3v coin cell batteries as of now but not sure i can find a rechargeable coin cell battery, if i cant find that type would one rechargeable 9v battery still provide same power as the 3 3v batteries? also how would i Eminem the type of charger cord to use?
