I'm replacing the batteries (2 x 12V, in series) in a Best power supply from
the early 1990s.

Obviously, I have a negative lead, a jumper to put the two batteries in
series, and a positive lead.

Attached (with tape) to the red positive lead is a white wire with a smaller
female spade connector on the end of it. The person who previously replaced
the batteries did not connect the white wire to anything. What should it go
to?

It should connect to a temp sensor buried between the cells and used to
detect an overcharge condition.

Thanks. I was thinking temperature sensor but didn't see one. I'll look
more closely. It's possible the previous person discarded it. (Maybe it
was stuck to a battery and was discarded with the battery.) That, in turn,
may be why the batteries lasted only 3 years in light use.

I found the battery replacement instructions on www.bestpower.com and they
say not to connect the white wire to anything at all -- which leaves
completely open the question of what it was originally for.

Its connection on the circuit board is labeled SM or WS depending on whether
you read it right-side-up or upside-down.
