Here, in this instructable it is shown how to make a solar 1.5v Rechargeable Cell.
For this project we will use useless calculator and reuse it!
By charging the cell with this method you can use this cells in Camera and other equipments.
Step 1: Gather Materials
1. Useless Calculator having solar panel
2. 1.5v Cell Holder
3. 1.5/1.2v Rechargeable cell
Step 2: Extract Solar Panel.
Extract the solar panel from the useless calculator.
Step 3: About Solar Panel
The solar panel extracted from Calculator generates about 2.9v at a time!
Step 4: Solder the Panel!
Solder the positive terminal of solar panel to positive terminal of cell and vice versa.
Also affix the solar panel to cell holder with glue.
Step 5: Process of Charging
Affix the cell in the cell holder and your cell will start charging.
To charge your cell fully to 1.2v 60mA the time needed would be 9 hours.
Hope you like the project!
