Today I learned... batteries




One of my students who is a battery engineer (who knew they existed :O) told me that the perfect percentage to keep your batteries is at 50%. This ensures that the positive ions (?) and negative ions are balanced.

When a battery is dead at 0% all the ions go to the positive side and when a battery is fully charged at 100% all the ions go to the negative side. This makes the battery very weak and vulnerable.

please excuse the contents... 😅

Her suggestions were if you want to maintain your phone at good health, charge your phone battery when you sleep (we were mainly talking about phones, which is the biggest concern for most people and also the most used device with a lithium battery) and do not charge it again till it reaches 30%.
