Some battery chargers and analyzers have a "wake up," "recovery" or "boost" feature designed to wake a sleeping battery.
How long does it take to charge a lithium ion battery?
Return the battery into the lithium-ion charger and give it a full charge, which should take around 3 hours depending on what type of Li-ion battery you are reconditioning. Some chargers automatically progress from recovery mode to charging, so on these devices you can just leave the battery in place throughout.
How to avoid lithium ion battery overcharge?
The way to avoid this is to handle and charge them correctly. Most all lithium-ion battery packs or single batteries have some kind of protection circuitry built into them to protect the cell from being overcharged, short circuited, or over discharged. Multi-cell packs have an added feature called a battery management system with a balance function that monitors and distributes charge current and voltage across each cell, making sure each gets charged with the same amount of current and voltage. That said, you must use an appropriate charger, either for single cells or one that supports multiple cells in a pack such as a balance charger. Using any other charger could cause the lithium-ion cells to overcharge and result in a fire.
How to connect lithium batteries?
Lithium cells in battery packs are always connected by spot welded tabs that connect the positive and negative terminals and you need to be careful when cutting them. Use the side cutters or the flush cutters to carefully cut the tabs between the cells and avoid shorting across the terminals. Be careful not to damage or remove the protective wrap on the outside of the cell as you can short on the metal body as well while cutting the tabs. We don't want naked batteries. Use the needle nose pliers to remove the tabs by pulling them off. Be careful. The cut edges of the tabs are razor sharp!
