On this iMac (2012 i7) Bluetooth has always worked fine.
Was working fine today as well until it suddenly began dropping out intermittently. Off for 10 - 15 seconds then back on for 10 - 15, repeat.
Tried various things - disconnecting and re-connecting devices (when I
could) plugged in a wired mouse to help and eventually the charging
cable for the keyboard ...
Disabled and re-enabled BT.
"Removed" the devices from the BT device list.
Etc. and so on.
But it kept dropping out and coming back (this includes the BT "symbol"
in the status bar changing to a horizontal squiggle).
Finally shut down the Mac and re-started.
Vestiges of the same issue for a bit, but went through the cycle of disconnecting and re-connecting; turning BT off and back on again.
[1]
Now seems resolved. TBD.
If it occurs again I'll try clearing the associated plist files and re-starting. (A suggestion I just found online).
Possible log related reports (after re-boot)

It's more likely to be an environmental issue than a software issue.
There are many devices that use radio signals in the 2.4 GHz spectrum
that can and do compete with Bluetooth radio signals.

I also see this on my iMac 2012.
Being out of update support, it is very rarely rebooted.
It is getting a reboot now.

Interesting - I typically reboot about every 30-60 days depending on
system behaviour. But in the past month I've had to re-boot a few times
to get certain things going again. One weird one is iCloud issues after changing the appleID password. This usually causes issues with Messages
(esp getting SMS texts relayed from my iPhone) and reboot is the only
cure I've found to date.
A couple other apps also seem to benefit from a re-boot from time to time.
Waiting for Apple to come out with the next Mx iteration (M3 perhaps?)
before migrating off of this iMac. Not clear if it will be an iMac or a Studio / Mini or ... what yet. But as usual, higher end spec (not pro)
to last another 10 years or so.

I doubt deleting preferences is the solution. I would try rebooting
first. I would also try toggling Bluetooth off and back on. And I'd try deleting (forgetting) the affected Bluetooth devices from System
Preferences > Bluetooth and adding them again.

This may be an irrelevant observation, but... The $5 flip-phone I'm
weaning my way away from requires Android File Transfer (from the
G-word) to move photos, ringtones, etc. to and from my Mac through a
wired connection. AFT would consistently kill Bluetooth until I traced
the issue to a user agent the app was trying to install when launched.
Kill user agent, Bluetooth returns.
I guess the only way I found the culprit was through trial-and-error
and careful observation. Like I said, this may be totally irrelevant
to the problem at hand.

I have rebooted multiple times. I turned off Bluetooth before swapping peripherals with my 2019 iMac. I used a Lightning cable to pair the
newer peripherals and that seemed to turn Bluetooth on. The new
peripherals worked reliably, but could not wake the iMac. I rebooted and Bluetooth was off. I turned Bluetooth on and the disconnects were back,
but peripherals could wake the iMac.
I plugged in a wired set of peripherals for now. I could try a
reinstall, but how much can I sync back before the gremlins move back
in?

Have you done the SMC / PRAM resets? Probably not needed but ... cheap
test.
Beyond that, try holding the rabbit ear antenna while drinking a glass
of water...

CMD-Option-P-R + reboot seemed to fix it. I browsed a safe site for a
while and watched a ~20min youtube video with no disconnects. Keeping
the wired peripherals on for now.

Oddly enough one site stated that a PRAM (or SMC) reset could not help
this issue which is why I threw it out there as a last resort ...
Hope it holds together!

I now think that part of the problem was using old rechargeable
batteries, that had developed high internal resistance and couldn't
supply spikes of power.
Which batteries do you mean? In the peripherals? I'd be surprised if
that was the answer. Have you tried new rechargeables?

Yes, the peripherals.
Yes, I am now using newer LSD batteries.
