Laptop CMOS Battery change. Practicalities thereof.

[Carruthers]

I have a Novatech X60MV laptop more often known as a Clevo M77SU which is in need of a new CMOS battery.

Unfortunately, it is not a question of removing the old battery from a circular housing on the mother board and slotting in a replacement.

The battery has two soldered leads which are plugged into the mother board somewhere out of sight.

It might be worth, at this point, referring readers to this thread which discusses the same problem:

X60MV CMOS battery

If you've glanced at the thread you will have read that the OP ended up splicing and soldering the leads as the socket on the mother board wasn't easily accessible.

Now, I've ordered a replacement battery (with leads) but I just wondered if anyone can recommend another way of splicing the cables, perhaps by a miniature plug and socket of some sort.

I am, or was, reasonably adept at soldering although the soldering iron might no longer work as it has been out of service for years, and I would prefer not to go down that road.

So, Dwellars assembled, any recommendations as to alternatives to hot tin and lead, please?
