Quark Mini 2AA Battery Question
the manual says the same thing, but this is precisely the issue. it was a time when L91 batteries and the like were new, and not every manufacturer mentioned their compatibility with. For that matter, L91 have a resting voltage of 1,8V, 3.6V combined. That is why i am asking- kosPap

Quark Mini 2AA Battery Question
hi all! I am planning taking the Quark Mini 2AA off the shelf, and using it as my travel bag flashlight. Question is...can it handle 2xL91 batteries? (1.5V lithium non-repleceable, with a real output of 1.7+V) What is your experience?- kosPap

Old LiIon Battery voltage settling/drop after full charge
thanks all for replying so far.... question is: how low would a battery, with 20% or 40% of its capacity lost, show (resting voltage)? Here are some voltages measured 20.11V for a 20V power tool battery 10.96, 11.78V for a 12V power tool battery.- kosPap
