We all are fed with the fact that dry cell is not rechargeable and it has no use once it is discharged during use. And, people simply throw it away and buy a new one. Because of this, people are forced to invest quite a lot on battery. In order to overcome this problem, here we have presented a new project ‘Dry Cell Charger’, which has been tested and verified practically. Using the circuit dry cell charger one can charge dry cell 6 to 8 times which evidently contributes to the fact that our expense on the battery is reduced from 6 to 8 times.
Circuit Description of Dry Cell Charger
The overall concept of the circuit is so simple that any normal individual can understand so clearly. The circuit of dry cell charger utilizes very few components and offers economical benefits as well. Â Talking about how it works, the circuit is based on PCR (Periodic Current Reversal) principle, where low AC voltage is given to dry cell for charging. A 6V-0V/1 amp secondary transformer is used to step down the AC voltage supplied. The average time a dry cell takes to charge is approximated as 12 to 16 hours.
