Cycle recovery charging (CRC) methods for single used lead-acid batteries

There are many kinds of batteries available for use as primary power source, backup power source, or storage devices. Among them is lead-acid battery-one of the most important and widely used device in many applications due to its low cost and continually improved technology. This paper presents a cycle recovery charging (CRC) method for single used lead-acid batteries. Experiments tests were performed on 12 used lead-acid batteries (12V 60Ah UMTB FIAMM AGM) that were retrieved from storages of telecommunication companies in Jordan. The findings of these experiment tests show that these new charging methods have achieved significant improvements in battery charging performance. These improvements are effective for reconditioning of all batteries in use, extending the service life of the batteries, recovering capacity by breaking up hard sulfate, recovering cell imbalance, and refreshing batteries.
