Why nickel batteries fail and how the renew cycle works?
When a nickel cadmium battery expires, it is usually because one of the cells in the pack is damaged. The lowest capacity cell in the pack is subjected to the deepest discharge cycles and possibility of polarity reversal. Since this lowest capacity cell endures the most punishment, the overall performance of the battery will depend upon this cell. If nothing is done to prevent damaging reversal conditions, this cell will prematurely end the battery’s life. To maximize the life of a battery, it is important that the cells work in unison. This is achieved by maintaining an even level of charge between cells. The renew feature of our battery analyzers and chargers achieves this through four steps. Step 1, Standard Discharge. The battery is discharged to 0.9 Volts/Cell removing most of the available energy from the battery. Step 2, Deep Discharge. The battery is carefully discharged to 0.6 Volts/Cell. This removes the remaining energy from the strongest cells. The deep discharge is done sl
