Here are 4 lead acid battery charging circuit projects, for 6V battery or 12V automotive, it is easy to use, with automatic charger control circuit [...]
This is the simple solar solar radio battery charger circuit. A solar cell radio used a 3V (or two 1.2V) Ni-Cad battery in it. The battery can not be removed. It use a mini jack socket for charging. Its quiet difficult to find such a voltage charger.
Here is Universal nicd and nimh battery charger circuit. It use IC LM317T ( Hot IC) Control Current less 300mA, Size battery 2.4V,4.8V,9.6V. Low cost circuit
This is IC 7805 constant current circuit for battery charger, It is advantage that we have IC- 5-volts 1A positive voltage regulator as current regulation
The project is the NiMH battery charger circuit on automatically shut off when fully charged. Can charge batteries 1-10 pcs. Depending on the input voltage [...]
Let's build a small solar AA battery charger. In an era of expensive energy better. In an era that energy is more expensive every day. Alternative energy is a good…
This circuit is formed maintain one's position voltage from solar cell with , shunt regulator circuit. For protect voltage not too until much destroy battery. Because of something charger too…
