Default CR2023? CR2032 Batteries

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)

Default CR2023? CR2032 Batteries

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.

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.

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.

"There is no CR2023 battery"

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

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 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.

"Bull****. Digikey is a major worldwide electronics distributor, and
the 2032 is a very popular coin cell. "

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

I said that I had gotten bad ones in the past. Someone said something about Digikey and I replied that the bad ones were not from Digikey.

Are YOU sober ? WTF is your problem ?

There are 2023,2032 and 2025 batteries. My blood test meter calls for 2023. Don't know if the others will work equally well even though they are the same diameter.

The differences are load capacity. See the chart below:

Voltage Capacity
2023 3V 225mAh
2026 3V 163mAh
2032 3V 210mAh

All other specs are the same.

That can't be right? The thinnest one has the highest capacity. A
typo, maybe? I'd guess 125 mAh would be about right.

That 2023 is a typo, should be 125mAh
