This is dangerous and stupid. NEVER DO THIS! Battery packs for tools have internal protection circuits because lithium cells become dangerous when they fall to a low level. The pack is trying to protect you from a fire/explosion which can and HAS resulted from forcing a charge into a under volted pack. The worst thing is that cheap packs use cheap cells and they are even MORE LIKELY to catch on fire/explode if you try to charge them after they've fallen below the safe limit. (For further ref, 4.2v to 3.0v is the range cells are ok at, below this voltage and charging becomes dangerous.) Why is RUclips allowing this kind of content to be published? This is basically instructing people in how to make variable time bombs in their houses.
Amazing tips to restore old lithium batteries! Quick, effective, and super helpful for saving money and reducing waste. Great video!
I never realized how many uses plastic bottles have! These ideas are so creative and eco-friendly. Can’t wait to try them out!
I am watching you from United Kingdom
Great info except none will last and you damaged your good battery by shorting it through the bad one..
