Discussion Do 2032 Computer batteries recharge?

[K12gamer]

How long do they typically last? Are there any special brands or versions best for PCs?

What are symptoms this battery needs to be replaced?

Can you even put those in a computer? That's the battery that's in my remote control key for my car.

And no, I don't believe they're rechargeable. I've typically just replaced the battery when my key gets low.

I think most PCs have them...They call it the CMOS battery. I though they might stay charged from the PCs power supply.
I had a PC whose date and time became way off...and the bios became screwed up...making my PC fan continuously run really hard.
I think these negative effects were from a dead CMOS battery.

You're right, a dead CMOS battery will cause the BIOS to continually lose the date and time, causing issues with the OS and other things. I believe they aren't recharable, as my dad (a computer tech) replaces them rather often in clients computers. Just replace it and reset the date/time settings and anything else that you want changed in the BIOS, and you should be good.

For my experience ~5 years but could be less or more aswell depending of the computer use. Yes, strange things will happen when bettery runs low. Rechargeable batteries do also exist, but never used these. More here http://superuser.com/questions/396019/how-long-does-cmos-battery-3v-on-a-motherboard-last
