how to safely remove battery cells from powerbank?
In the Navy there was a tale about someone using a Fluke 189 by deeply pressing their thumbs into the leads and passing dangerously close to reality. It’s not real, but it might describe a situation where you could deliver 100mA to the heart briefly.
I’m trying to save the cells and might use them later. Not a do-it-yourself project but they could be useful. Does this mean I start by cutting, then connect the negative side? The battery is about 2.7 volts, so I doubt anything will happen. Should I cut the connection where three batteries are joined at the side? On this power bank, the three batteries are separate from these two. (I believe it has two positive and one negative on the side next to the charging port.) Plus is on the side with the charging port, which connects the two batteries that are linked together, while the top three are separate. Thanks for the info!
it doesn't matter as long as you remove one at a time, then the next. it was originally about avoiding cutting both at once, which isn't a good sign. this suggests the cells are in poor condition and may not be useful for other projects. carefully sever the connections between cells and the board, ensuring you don't damage the wires near the cell sides. after cutting, double-check that nothing remains touching what it shouldn't.
