I could swear the battery I removed was 2023 but when I went to the store
I pulled out a 2032 which might have gotten confused when I looked for
2023. But the 2032 I bought fit into the socket.

The computer in question still has CMOS errors,
so I'm wondering if I popped the wrong battery in.
But it fit perfectly in the socket.

THis is a 1995 Gateway (GW2k) P5-75 CMOS battery.

If it was 2023 I lost the 2023. Are they similar enough? Is there any way to
check which one was used by Gateway? (I had found a completely different one
online when I searched a few months ago which is why I was susprised which
one I found)

According to the internet they are pretty much the same. An old PC like that might need some manual configuration. I'd pull out pretty much everything and load setup or default values and see what happens. then add stuff one at a time, probably starting with the harddrive.

There is a CR2025. Many motherboards of that vintage used them, but probably
just as many used the CR2032. They are close enough in size that a
CR2032 will fit in a socket for a CR2025 that is basically a cup with
tabs to hold the battery in and a large flat spring to contact it.

There is a socket that looks like the letter U where the battery slides
down into it, and that is too close a tolerance for a CR2032 to fit.

At this point, if it works, make a label that says CR2032 on it, and stick
it on the motherboard. :-)

>"There is no CR2023 battery"

It appears I found a typo on the internet. (oh dear lol)

I think you misread the number. There is no CR2023, but there is a CR2025.

The difference among these cells is their thickness, which translates into a
difference in capacity. There is nothing wrong with using a higher-capacity
cell than required, unless (as someone else pointed out), it doesn't make
proper contact.

It's a good idea to keep a separate list of the CMOS settings, "just in case"
you have to re-enter values appropriate to your computer. In principle, any
computer should boot with the default settings.

A CR2032 is 20 mm diameter, 3.2 mm thick, 225ma-hr
A CR2025 is 20 mm diameter, 2.5 mm thick, 165ma-hr
There is no CR2023 battery.
Either will fit in a 20 mm dia battery holder.

The only real difference is that the 2025 is thinner and may not make
as solid a connection as the thicker CR2032. You can bend the top +
terminal on the battery holder to compensate. However, I'm fairly
sure your ancient Gateway uses a CR2032 battery and that you bought
and installed the correct battery.

Why it doesn't work is unknown.
Did you install it upside-down? The + goes on top.

Today we received the 2032 cells from Digikey. 100 pcs Panasonic for $19.25..

Don't pay those horrible drugstore prices.

Gotta watch where you get them too. I've gotten plenty of them bad outof the box.

Damn industry, they change every other damn thing just for the sake of change, but when it comes to these batteries you could be getitng them after they sat for twenty years, literally.

I'm not sure they'll work in 20 years when i need the last one.

In the drugstore you also pay for the plastic and cardboard for each
one, and for somebody to restock the pegs with the cardboards, perhaps
for somebody to put pricelabels on each one.

I don't know. One drugstore here for a while was selling generic
batteries of that kind, relatively cheap. They may still do, and simply
moved them.

I can get them for fifty cents at a the local outlet of the Big Chain
Hiking store here in Canada. Name brand too. Not absolutely cheap, but
cheap enough. Not every type either. I remember buying some small LED
flashers from the store (intended for bicycle use, but useful as handy
little flashlights since they can be put to a constant on) and thinking
when the button cells died, I'd be buying new flashers, since the
batteries would be as expensive. But the store carries replacement
batteries preciesly for that reason.

For odd batteries, some of the dollar store items can offer up button
cells of various kinds. I was buying 99cent laser pointers for a while to
feed batteries into small clocks and the like I had no problem with the
batteries. But then, I needed some white LEDs for something recently, and
bought a 99cent LED flashlight that offered up 5 white LEDs, Handier than
any other source, probably cheaper too. And it's no wonder those
flashlights often have an LED or two not working; the the LEDs in this
flashlight had one side of the leads twisted together (no solder) and the
other leads hoping to make contact with the case of the flashight for the
return. So it's probably a better source of LEDs than a flashlight.

It worked fine. Dunno why I thought it was 2023 (my home address is 2028
so I should have remembered right).
Oy, my eyes are old...

Gosh, I wish I knew a place that still made the battery for my 1980 HP2621
terminal. It loses the settings whenever I shut it off. I haven't used it on
a regular basis since 1995, though. But it worked so well. Gold contacts on
the keys, all I had to do was squeeze them with pliers when they acted up.
I should give it up - the glass is peeling and the glue gaps look like mildew.
Not in a big way, though.

So where's the problem?


One time I bought a nice LCD desk clock, I liked it a lot, though it was
no more than five dollars. When the button cell died, I was cheap, just
soldered an AA battery to it, which lasted even longer.

That sort of battery isnt' likely to be more than a few volts, so you
could just solder something else in. Uncover what voltage is needed and
then solder an alkaline AA or two in place. At worse, you'll have to
solder in a new pair in a decade or so. You could get fancy, use nicad or
nimh, but then you have to figure out some method of keeping them charged,
hardly worth the effort when the AAs will last so long.

That's to say nothing of your motherboard.

Wasn't from Digikey. It was a long time ago. Actually I haven't had one go bad in decades.
