For example:
<https://www.ebay.com/itm/275206338185>
The main advantage is that Li-Ion is rechargeable, doesn't leak and
has a low self-discharge rate. I've been using Li-Ion 9V batteries in
my various DVM's, LRC meters, and gadgets for about 6 years. All are
still running on my original replacement Li-Ion batteries. After not
being used for literally years, most of these devices are ready to use without having to replace the battery or clean up the mess from
leaking alkaline batteries. Unfortunately, Li-Ion does nothing for
gadgets that draw parasitic current when turned off.

I use 9V Lithium iron phosphate primary cells in smoke alarms when I can
get them - they are the same size as 9V alkaline batteries, but last a
lot longer - about 10 years - and cost more when you can get them.

I just use 9V Alkaline batteries in my multimeter
Does not leak, used every day, for more than a year now:
https://www.ah.nl/producten/product/wi136835/ah-9v-alkaline-batterijen
about 2 US dollies
I do use li-ion in many other things though, high power ones in my drones..
https://panteltje.nl/pub/charging_chinese_lipo_with_rc_plane_charger_IMG_5473.JP
And use a lot of 'Eneloop AA and AAA rechargable batteries.
those have close to zero self discharge too.
https://panteltje.nl/pub/gamma_spectrometer_supply_side_MG_6578.JPG
In li-ion in my cameras too:

There is an article from NIST on battery noise. (1133.pdf,
pubs are a moving target url @ NIST.) They may not endorse
products, so I repeated it with batteries I could actually
buy.

The lithium iron disulphide primary batteries from Energizer
have internal over-current and over-temperature protection.
There is an internal ptc protection device. The details for the
original cylindrical cell are in the Energizer patent.

Interesting, I take it the 'unloaded peaks' that are about the same frequency for all batteries are a local noise source?

Thanks. As far as I know, smoke alarm batteries are non-rechargeable (primary cell) lithium batteries and not LiFePO4, which are
rechargeable: <https://www.google.com/search?q=lithium%209v%20smoke%20alarm%20battery&udm=2>
I need to search for info on what cathode chemistry is used in
"lithium" smoke alarm batteries. Any clues?
