Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
Place your solar battery charger in a sunny location. A southern facing window would be perfect. Connect your battery to your solar charger. Wait about 45 - 60 minutes (remember this charger is slow.) Disconnect your battery and recheck the voltage of the battery.
Here is the simple circuit to charge 12V, 1.3Ah rechargeable Lead-acid battery from the solar panel. This solar charger has current and voltage regulation and also has over voltage cut off facilities. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable.
Output Voltage –Variable (5V – 14V). Maximum output current – 0.29 Amps. Drop out voltage- 2- 2.75V. Solar battery charger operated on the principle that the charge control circuit will produce the constant voltage. The charging current passes to LM317 voltage regulator through the diode D1.
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
The battery can be any 3.7V 1200mAh Li-ion battery. Motor can be any 3.7V DC motor. More Questions: Couple more questions, I cannot find a solar panel with those specs, do you think you could send me one on the internet so I can find something similar?

Applications of Automatic Battery Charger: Charging 12V lead-acid batteries for automotive, solar, or backup power systems. Portable charging setups where overcharging protection is crucial. You can make a 3.7V or 9V battery charger my modifying above circuit.
Stage#3: As the current drops, it reaches its lowest level which is lower than 3% of the cell''s Ah rating.. Once this happens, the input supply is switched OFF and the cell is allowed to settle down for another 1 hour. After one hour the cell voltage indicates the real State-Of-Charge or the SoC of the cell. The SoC of a cell or battery is the optimal charge level which
A 9V solar panel is too low, use 12V to power the charger. An 18650 cell is usually about 3000mAh and charges at up to 1.5A. A current of 0.5A will take 6 hours to charge them if they were low. All my RC airplanes have a bare 2S Lithium battery with no protection board. The battery charger circuit is 2S balanced and is separate.
A solar charger circuit is a device that generates power from sunlight. Cell phones, computers, automobile batteries, reading lamps, and personal fans all can use this power to charge their equipment.
