Introduction: Free Battery Charger
So my garden light failed and I wanted to salvage as much as possible.
Old garden light
Old rechargeable batter
Step 1: Step 1
Wire the circuit, use any diode as shown in schematic.
Step 2: Step 2
Re use solar panel from bad solar light. Tie down the wires so they don't came off the solar panel.
Step 3: Step 3
Use rechargeable battery 4 volts DC, I would think it will work with any rechargeable battery from 1 to 4 volts. I still need to test it for voltages other than 4 volts
Step 4: Step 4
Assemble and put outside to charge and recharge your batteries.
