by connecting a fully charged battery to the dead shorted battery you willl get very high current flow through the dendrite. That will casue it to get hot and melt. Hopfully that breaks the short. Modern lithium ion batteries rarely short out in this way. Also lithium ion batteries are very sensitive to overcharging. If they overcharge they can catch fire . So I would not recommend this with lithium ion batteies." Thank you steven4872 for the explanation.
