battery desoldering advice

[Jim Beacon]

Jay,

these things are usually spot welded :(

However, if you take the whole assembly out, you can usually prize the clip
of the battery without damaging either (you could use a burr in one of those
Dremel type tools and grind the welds out.

As for replacing, you can solder them on, but it is difficult due to the
plating on the clip and the battery, a good flux is required, and often, you
need to remove the plating with emery paper before you can solder to the
parts.

Jim.
