"cell, button" batteries
Discussion
any recommended brands of them as i have a bunch in iot devices and the initial battery lasted very well BUT the subsequent one lasted maybe 3 months the sensor is highly used but the less used ones didnt last that much longer. i bought some more and they lasted better but that high use one has just failed again
so i need something that lasts (wish id kept a note of the manufacturer of the original ones!)
not that it really matters but its a cr2450

Lots of fakes being sold online, I gather.
So perhaps best to get a recognised brand (e.g. Duracell, Energiser) from a proper shop, not Amazon/Ebay.
Basically this. I'm not so much of a fan of Duracells these days after some disappointment with their AAs (leak prone), but generally I'd stick to established brands from a reputable supplier. Consider also Panasonic or Varta for button cells.So perhaps best to get a recognised brand (e.g. Duracell, Energiser) from a proper shop, not Amazon/Ebay.
Alternatively, sometimes I might buy cheaper ones (but still branded, just less well known) and just buy in bulk and accept I might have to replace a bit more often. Stuff like GP or Pro-elec (which is CPC's own brand I think)
I've had a similar issue with our oil tank gauge, I didn't change the battery in 7 years, and it was in before we moved it.
Changed it every few months after, and hint of cool weather and it wouldn't register.
Tried all kinds replacements, then gave up and bought a new gauge as I assume it's somewhat faulty.
Same with the doorbell, it's on the north side of the house, and if it's cold it refuses to work.

Let me have a quick look in my battery drawer and I'll see if I have any direct experience, I'm pretty sure I have used some 2450s for a similar purpose
In this case it was PKCell CR2477s from Amazon which have been ok for me (especially for the price). I've also had pro-elec 1220s from CPC which I would be ok buying again. 20x PKCell 2450s are currently just over 6 quid : https://www.amazon.co.uk/CR2450-Lithium-Batteries-...
Sometimes the original battery lasts well because everything is clean and dry when it's installed by a robot in the factory.
You change the battery, by hand leaving traces of moisture etc, a few micro-amps of leakage makes a difference.
Sometimes the device getting a dit damp is what killed the old battery...
Sometimes the devices draw a little more current as they age.
I tend to look for brands I've heard of like Varta Panasonic or Enercell. I've bought coin cells from Ikea and they've been OK.
Mostly these things are so cheap it's not worth worrying,
Sometimes you can use a thicker cell of the same diameter, which helps with higher capacity and increase chance of having one in stock.

Buy from Amazon themselves and they're fine. Resellers through Amazon may be dodgy.
Sadly that black-and-white advice no longer holds true.Amazon's increasing use of commingled inventory - storing items from different sellers all together in the fulfilment centres - means that the item you actually receive has an uncertain supply chain. This used to only affect 'Fulfilled by Amazon' sales but now also includes 'Sold by Amazon' purchases too. Amazon-related discussion boards are full of reports of counterfeit products being sold directly by Amazon and they seemingly don't care and push buyers through the no-hassle returns process for resolution rather than change/fix the underlying problem. The real issue is not just that it enables counterfeiting but actually encourages it because suppliers of counterfeit products can now make money (and generate positive feedback etc) from the sale of the genuine article if that happens to be picked from the collective bin when their own customer's order comes to be fulfilled, thus leaving their above-board competitor to take the hit with a return of a suspected counterfeit product.
For batteries in particular I'd recommend going through electronics suppliers with robust supply chains (e.g. RS, CPC/Farnell, Mouser, Rapid etc) or supermarkets if in more of a rush or for one-off orders.
