- I wish I could say it was easy. Its not, the darned things (the tabs)
- are in fact resistance spot welded to the battery can, prolly before
- the rest of the battery is even assembled into the can. So when it
- goes, or even before, about the only way to rip those welds loose has
- a considerable potential for also ripping the board itself! So
- basicly, it still must be desoldered from the board so that a knife
- or something can then be worked under the edges of the welded on tab,
- lifting it with enough force to break the spot welds. *That* could
- possibly be something on the order of 150-400 lbs, depending of
- course on how good the original weld was. And equally obviously,
- damned hard on the board!
-
- Once removed from the old battery, then reinsert and solder them back
- into the board. Then solder the (probably soldertab style tabs) to
- the originals. Since its all stainless steel, a silver bearing solder
- would be a definite help. Standard 60-40 tin-lead alloys don't seem
- to stick to stainless as well as a 60-3-37 combo, where the 3 in the
- middle is silver. Its also a heck of a lot stronger when cooled.
-
- All that of course should make you go out on safari and find a
- battery with the '3 solder into the board' mounting legs. They are
- around, I spotted a suitable one at State Electronics, an electronic
- parts supplier in Fairmont WV, just last week. Might be somewhat
- popular even since he had 3 of them, and out of about 25 types, most
- were only stocked 1 or 2 deep. In the larger cities, it should be a
- piece of cake. Fairmont, home of Mary Lou Retton the olympics champ?
- About 20 thousand (on a saturday nite).
