14500 3.7V battery?

Got some 14500's for my flashlights....

I blow through a pair of NiMh rechargable AA's in my keyboard every other week it seems.

Could I use one of these 14500's plus a dummy cell? Or would 4.2 volts be way too much for the onboard voltage regulator? (I would imagine the board has a buck/boost to 3.3 or 5.0 volt for the BT modem?)

Mac mini, macOS 10.15

Where do I find a single source of truth re: proper use and maintenance on M1 Batteries Does anyone know where I can find a "single source of truth" as to proper use and maintenance of M1 batteries? Consider: Some Apple support advisors say it is okay to leave your power adapter continually attached (as the macOS will automatically stop charging at 100%), while others say never do that Some advisors say that using a USB-C cable attached to an external monitor will not charge the battery, while others will admit that using USB-C cable will charge (which I have validated thru my own testing) Finally, some advisors say that you should never go below 40% or charge above 80% while others indicate that you can/should charge to 100% and drop all the way to ??% (it varies). I have a MBP/M1/Max (32GB/1TB) with a battery that is losing ~ 10% of battery storage every hour, which seems excessive, especially when you consider that published tech specs are indicating that users can expect 14 to 21 hours over an 8 hour period. Thanks.

MBP 2020 battery Why doesn´t apple want to accept the fact that the battery on MBP 2020 works far worse than the battery on a MBP mid 2015 While on their official page they say that it lasts about 10 hrs navigating which I believe is a falsehood, Just been with my MBP 2020 on all the time and actually used it as per official screen time about 4-5 hrs only online and it lasted about 5 -6 hrs. Consider the fact that they have removed most of the ports that the MBP mid 2015 had and the MBP mid 2015 battery gives better performence than the MBP 2020 i5. We should consider the fact that apple is not standing up top facts and readily blames MBP owner use while it is it´s own false advertising

Update: 14500 lithium battery and a dummy cell work just fine. The end cap still screwed on, but it's about half a turn from fully seated.

Unfortunately, the higher voltage did not improve the weak bluetooth connection from keyboard to my Mac Mini (still only good to 2.5 feet at best)
