I have a similar vacuum. Just replaced the cells in mine. I used Sony VTC5a cells. Higher capacity and discharge current to the original LGDAHB3 cells. I soldered the wires to nickel strips first and then spot welded to the cells. Prevents heat from soldering potentially damaging the cells.

[@Mobilant_US]

Yes, that is a better method. The method I used is also good because the heat conduction rate is not fast. It is the method I used when building several electric bikes. No damaged cells were found.
