Hi guys recently I buy wireless mouse ,for switch on the mouse we want AAA size battery. I used continuously for PC within 3 weeks battery discharged .so I decided to do rechargeable wireless mouse.

Step 1: Material

@ IN 4007 diode -1
@ LED ( red colour for charging
@ charging connectors -1
@ lithium-ion battery (800-1500mah)
@ 470 ohm resistor-1
@ hot glue
@ PCB board


make it circuit on pcb board with components, make it small to fix inside the mouse.

Step 3: Cut Out

make a cut out to fix the connector .using hot glue.

Step 4: Assemble

fix inside the battery as per circuit image.

Step 5: Finish

I did not image the PCB board fixing in mouse because that I cannot have camera .u can try it as per circuit if any doubt ask to me..
Be careful! A Diode is not a proper Li-Ion charger. A Li-Ion battery needs a special charging circuit (Constant Current, then Constant Voltage) The cell could explode if its charged too long.
we want to maintain the charging time 1-2hours
<p>Cool! The design it quite clever, and you explained it very well. Thanks for sharing!</p>
<p>Does the rechargeable battery that you used has an internal circuit to manage charging? Otherwise, the circuit that you designed I do not see how it can properly charge a lithium battery, since the charging process is quite complex. The circuit you posted I guess is to charge a lead acid battery. Am I wrong?</p>
no it only to charge lithium battery
