The US Air Force was able to deploy NiCd batteries that had been in storage for 5 years with good recovered capacities after priming. It is believed that priming becomes necessary if the voltage drops below 1V/cell. I would guess that, but that's only because I use a T60 and an X31. PC, Plese give me the approximate internal resistance of Li-Ion cell (dV/dI). When you or your childs temperature rises a few degrees above normal, its a sign that the body is healthy and fighting infection. Now I want to store them until I want to use them again. I can hear slight boiling of the electrolyte (few bubbles here and there). What would be better for a saving of a Lithium Ion battery: to be in every day working laptop using external power or in a fridge?

Usually, this is F12, F2, Esc, or Delete your computer will tell you during its bootup process what to press to open BIOS (or Setup). The Embedded Battery Management System (BMS) does a reasonably good job giving SoC information but the measurements are seldom accurate. Make sure this fits by entering your model number. I will just point out to heat a well isolated volume of air - you need not so much energy. Thanks. Low 42F. You would hardly be charging the battery - merely keeping it in good condition.
