If you do a google image search you can see examples of CR2023 batteries that have leaked. Seems like a problem in some SNES cartridges. It is a question of how many years you choose to ignore a device with a battery. 10 years? 20 years? or 2 years?
I don't think you can be guaranteed. I think you would want to replace every 10 years.
Well you would want to remove it anytime you know you won't use the device for a long time, if you use the device all the time you will know when to replace it because it won't do its job anymore due to low power.
Because Acid is corrosive, it's normally pretty safe but when it gets old or overcharged etc it's chemical composition changes, gets ionized and the acid goes from harmless to harmful and eats away at the seals.
The battery on mobos is only to keep the bios settings that you change, that was this way since always. If the battery runs out the bios will run with the default settings and if the only thing that bothers you is the time then that's the only thing you need to change, if you were booting from something other than the first port on the mobo you would have to use the boot menu every time.i understand that if the desktop is put to sleep, the motherboard is using the PSU's power and not using the battery's power but what if the desktop is shut down but the PSU is still powered on - will the motherboard receive power from the PSU or will it be using power from the battery ?
funny thing is i had a 10-year-old Acer desktop and the original battery didn't leak...............when the battery power went out - i just need to adjust the time and everything worked okay................so looks like the battery is only for keeping time nowadays ?
Your basic problem is buying consumer level goods, putting them on the shelf for a decade...in high temp and high humidity conditions, and expecting them to 'just work'.
Batteries are not soldered in anything retail I can think of. There needs to be a means of disconnect. In a pc, the battery just sits in a holder, exactly the same as a watch or your TV remote.
You should power it down completely, in sleep all the components still get power and changing ports with power still on the cables can damage the ports.i just realize the guy that fixed up my pc connected my boot drive to the 3rd SATA port............so can i just put my pc to sleep..........and then just swap the SATA data cable ?
Magic words, but nowadays, everyone makes those batteries, eBay is full of them, shipped from China, for $4 for 20 count etc. And that's where ppl like Dollar General, Dollar Tree and all the other 'Dollar' type bargain hunt stores get their uber cheap batteries from. Why spend $6 at Home Depot for 1x Energizer Eco or Duracell extended life, when you can get a 2-pack from Dollar Tree for 99¢
Which is a useless statement.
