Hi @d_p ,
I like questions to clarify !
I am occasionally charging the main battery, my occasional use can sometimes change but charging say 30 minutes at most every five days. I have not checked the charging calculations a few others have posted. These may also be affected by the variable charge rate available from the Framework supplied charger. I have yet to look into this, but I will wait to see how long it lasts before it refuses to start without ac power.
Originally I almost certainly didn’t charge the machine for 24 hours or more just enough to get 100% ish on the main battery. I found that regardless of the main battery state which was anything from 60% to 90% it didn’t boot without ac power. I didn’t record times etc. as not awre of the problem until I posted here.
I am not sure the CMOSB ever? gets any power from the main battery? A new one on me.
The occasional charge I give the main battery I don’t think gives the CMOSB much of a boost and so this is an unknown. I will complete this as as is, then look at maybe a slightly different approach. A lot may depends on the charger and its varying power …
From here…
" With PPS, the adapter can also be used as a programmable power supply in increments of 20mV and 50mA to further improve efficiency on devices that support it."
As and when I will find out if the varying rate available affects the time it takes to charge the CMOSB.
The one good suggestion I got from a post I just made on checking the CMOSB charging and voltage was to get a blank module (like the USB etc) and run wires from the battery to it to measure the voltage day by day etc. Maybe invalidates the warranty though.
Regards…
