What is the fastest way to discharge a lithium ion battery?
Answers
Answer:
Explanation:
If you short the terminals of a battery or cell, you risk having a fire, explosion and/or red hot conductors. Using incandescent lamps is very good due to the resistance decreasing with a decrease of temperature; the more discharged the battery becomes, the more rapidly it gets discharged.
One oddity you'll run into is the weak cells can get charged in reverse polarity, while the remaining good cells still will have a positive charge on them. That's why a battery seems to recover after its been discharged heavily, then allowed to rest for a period of time.
If you need to guarantee that every cell within the battery has been fully discharged, you will need to open the battery pack and discharge each cell. Remember. you're getting rid of these batteries because they won't hold a charge - it's actually just one or more cells that have gone bad.
