Replacing lithium ion cells in an old laptop battery pack, I want to connect the new cells in parallel before removing the old ones to avoid the BMS locking (if it even would do that). The pack uses three parallel pairs of cells in series to make 10.xx volts with low and medium taps going to the BMS.
This is why it’s a good idea to disassemble lithium-ion battery packs for its cells. In most other cases, just a single cell has failed. Remember, battery packs are made of many cells that are grouped in a specific way. So, if one cell dies, it will bring down the cells that it is immediately attached to.
If a relatively new pack has only one defective cell and a replacement is located, exchanging the affected cell makes sense. With an aged battery, however, it’s best to replace all cells. Mixing new with old causes a cell mismatch that has a short life. In a well-matched battery pack all cells have similar capacities.
Ensure that all components of the lithium battery pack are present, including cells, wires, terminals, and case cover. Assemble the cells into their respective terminal connections. Securely connect each cell connection using cables or solder depending on your model's requirements.
By replacing the cells in your product's battery pack, you can save money and reduce waste. Here's a DIY solution.
Quality cells for a multi-cell pack, on the other hand, are capacity-matched, lest they fail. A battery shop may salvage good cells from a failed pack for reuse but the recovered cell should be checked for capacity, internal resistance and self-discharge – the three key health indicators of a battery.
For troubleshooting complex battery failures and attempting to fix li ion battery, technicians might use specialized tools to analyze individual cells within a pack. This could involve impedance spectroscopy or other techniques …
