So, long time no see
Here (link to google sheet)
you can take a look at the performances of different batteries, tested with the charger, read the notes to get more info.
The charger: the hardware is the same, the software went throug various tuning but the main ideas remain (charge profiles and so on), I've done some fixing, counting mistakes, cicles and little else.
Temperature: I've got a IR thermometer, now I'll measure why (some) od those batteries are colder than the others. It only happens after a full charge, with my charger.
Sooner or later I'll ran the remaining test of how much is the Nokia charger charging vs my profiles.. but now life has changed a lot since my last post, moved out, found a job, paying my bills and got a QWERTZ keyboard and a lot of accents to deal with :>
My time is now shared among job/survival/hobbyes - being the first one quite compulsory, and the last two thread locking each other out :> - I could survive without food/cleaning for up to 1 week however... better not try
