Take a photo of the motherboard with a DC and upload it, and everyone can help you find it!

There definitely is one. On some old motherboards the battery is cylindrical. There is also another kind of motherboard that may use some sort of sealed-in battery. I once saw a motherboard with no battery on it, but there was a square-box-like component; you had to use a wire to short its pins in order to remove the password in the BIOS.

There is indeed a kind of motherboard with no obvious battery. Actually it does have one: it is a rechargeable battery sealed inside the motherboard. Generally only relatively old motherboards have this situation.
我完全同意设想建立DOS组织“DOS联盟” ，也就是说和Wengier、以及“起步”站长莫老师等DOS战友一起来建立这个“DOS联盟”，以发展我国自主OS（操作系统）的高度去完成我们共同的愿望。

Probably. In 1995, in the school computer room, I saw a teacher's machine where I couldn't find the battery on the motherboard. At the time I had originally wanted to discharge it to clear the coms password and get into his machine, but ended up dumbfounded...

If there were no battery, how could it display the correct time and date after booting? So look carefully.

A motherboard without a battery can still save information; that really is too advanced. I don't know what chipset it is, but the big chipset manufacturers should learn from it!!

That must be using something like a DS12887. This kind of thing combines the battery and CMOS RAM together.
But aside from industrial control, very few consumer motherboards use it now.

Let me tell you
If you can't find it, it is generally inside a 26-pin IC. This IC is the
CMOS storage chip

I've also run into this situation. I also wanted to discharge the motherboard, but couldn't find the battery. At the time I wondered if it was on the back of the motherboard, but I didn't go look. I suggest you try looking on the back of the motherboard.
