Just revived a dead lithium-ion battery pack of a robotic vacuum cleaner. Dont need to buy new one.
Battery was charged over night but still not charging up - failed.
Took out tge battery it measured 16Vdc.
Use a car battery charger to spark a few times on the lithium-ion battery pack. Then charge it.
It works! It is charging. Then 2hrs later the battery pack is fully charge and vaccum cleaner works again.
See this video.
