Are battery terminal solder onto the battery?

[JoeG]

I recently acquired a vintage 386 PC that has a barrel type of CMOS battery mounted on the motherboard. The battery needs to be replaced. I'd like to leave as much of the existing mounts that are connected to the battery in place on the motherboard because the replacement I will be using has a different prong configuration (two on one end, and one on the other end), and it would make replacing easier. The original battery has one prong at each end.

Are these mounts soldered to the battery? If so, can I use a SMD heat gun to slowly melt the solder and remove the battery from the mount while leaving the mount still soldered to the motherboard?

Here's a photo of the intended replacement battery for reference only on the mounts (I will not be removing the mounts from the new battery).

Thank you!

Not solder, those are typically welded. Don’t know how safe is to attack a battery with a soldering iron…

The pin configuration on the battery is like that so it's not installed backwards.
I see you're replacing the CMOS battery with a NiMH battery.

[JoeG]

Yes, it has a GP 3/Gp60K 3.6v 60mAh B 2 on it now. The one is the photo is the new replacement that was recommended by Jameco's website.

Thanks for the reply born2laser!

I'll snip the pins as close as I can.

Here's a 2-pin version.

or from Jameco

That one from Jameco looks like the one I should have ordered. That's what I get for trusting their website recommendations. But I'll try what I ordered and see if I can get it to work. If not, I'll order some of these.

Thank you!

I keep the two-pin type in stock, it seems to be what is most often used in vintage gear.

Had I known, or looked, I would have ordered from you Jeff. Who knows? I still might?

Thank you!

The Dial-a-ROM blew me away!
Neat!

Excuse me. I’m not a native English speaker. What is the difference between to solder and to weld?

Neither am I as a matter of fact, but I have been exposed to English for technical subjects for years.
You can get tons of information by googling that question, for the purposes of the discussion here we are talking in particular of joining two pieces of metal by applying very localized heat and pressure, enough to melt both pieces together in little spots without increasing the temperature of the rest of the part.
For soldering you use much lower temperature to melt a third material that then sticks to your parts, but you need to heat them up to higher temperature than if you weld them.
Welding provides very strong joints that can be done very quickly, I have seen it used for all battery packs, even done it myself to recell the pack in my IL printer


Hope that helps,

Juan

Welding = Soudage (https://fr.wikipedia.org/wiki/Soudage)
Solder = Brasage - mais on utilise un fer à souder pour ce processus (https://fr.wikipedia.org/wiki/Fer_%C3%A0_souder)

Now, let's further confuse the issue by bringing the word "braze" into the discussion!
(just kidding!)

Merci ! It’s clearer.

In Spanish is even more confusing. The same word (soldadura) is used for all three processes (solder, weld and braze), there is a second or more words to differentiate them, not used when the context makes it unambiguous, but you may not know the context…
