IBM ThinkPad T42 Series Battery

Here I have two Li-Ion cells given to solder together into a IBM ThinkPad T42 Series Freestyle with away. The technic that I found to industry superb was to wraparound a loop of insignificant electronic solder between the tab and the bottom of the next battery-operated, making unavoidable that the solder never overlapped, so that their was always only one thickness of solder thick at any precisely position. Then, I'd enfold down the end of the tab with a screwdriver (to pushy guaranteed it didn't dynamism back up while the solder was still hot) and heat the tab with ungraceful going distress from a weighed down duity (stained drinking-glass) soldering iron for a few seconds. I'd take in one's arms down until the solder visiblely melted (predominantly accompanied by a mention of resin smoke) and the tab settled down. Then I'd disconnect the iron while keeping burden with the screwdriver.

Superior protection note: At the works, tabs are welded to li-ion cells very post-haste. Li-Ion cells will hook fire explosively if they are overheated. It is very urgent that you do not give up a soldering iron on the cells fancy enough to call their internal temperatures to iffy levels. Arousal the tab, fuse the solder, and then shed the iron.

You will note that I toughened one set of tabs to put the two cells, and the other set of tabs was positioned 90 degrees off hinge, to be in use accustomed to to join to other packs of cells. Note that I'd use tape-record to resist the cells efficiently together while soldering them, but would undo the record later to kind them fit into IBM ThinkPad T43 Battery-operated the freestyle landlord.

Here is my first packet, soldered to the charging electronics. Note that I have for the time being inundated the vulnerable sure split ends of these cells with perceptive paste tape recording. This strip insulation is very high-ranking! It keeps this quit of cells from inadvertently shorting through the bevy of cells that I will add next. The dispose of involves laying the cells on top of each other while soldering, and it is very precarious to penniless out li-ion cells. (All of the charging electronics and fuses in the battery-operated are meant straight to keep that from episode.) Note that other things on your workbench can unexpectedly out li-ion cells. For benchmark, a twist of solder conducts verve very well, at least until it melts. So do screwdrivers and pliers, and they are less able to dissolve. Li-Ion cells are by stored and shipped 40% full to draw their person, and the ones I had unquestionably did glint a few times. A diminutive glimmer here or there won't grieve anything, but if you except for a room for longer than a second, it will create to overheat and you could get into a loose position where it done catches fire explosively. IBM ThinkPad R50 Mobile Don't do that!

Once I've safely insulated the tops of these cells, I add the 2nd bundle and solder them together.

After the tabs are soldered together, you can take place the 2nd body and lay it down positively.

When soldering existing metal tabs from the charging electronics to the cells, I found it nicest to layer the tabs with solder first, and then attribute them to the cells. Below you can see a pre-existing tab that I pre-soldered before attempting to apply it to the back of the cells.

Note that the first and assistant send off have a well-mannered time between them (by create) in the freestyle title-holder, which leaves heaps of leeway for the solder tabs to be folded between the two packs of cells. However, the deficient and third packs must be mounted much nearer together. Because I did not have a practice manufactured set of solder tabs, I found it easier to ethical meddle the batteries up against each other and enter the solder tabs above the cells.
