I am not talking about this website here, I am talking about another one that is mainly a question and answer site. I also see lots of times the "best" chosen answer is actually flat out incorrect.
So basically guys it's about charging lithium batteries like in a laptop. The person claimed that if you charge a lithium cell at lower than the suggested charging voltage that it will still take the same time to charge as the suggested voltage, but somehow the battery will claim it's fully charged at the voltage that is commonly known as the limit. (Like 4.2v generally). He said it will really only be 50% charged but everything will report it as fully charged 0_o.
This person also claimed that if you charge the lithium battery at a voltage higher than suggested and charge it really fast, it will have a longer discharge time.
How does this even make sense? Plus I am pretty sure the way to change charge times is to change the current in which you charge the battery at, I am pretty sure that you are not meant to adjust the voltage and somehow charge a lithium battery at 6V and lets say 400mA.
Pretty sure you should charge it at the suggested voltage and just raise the current instead if you want it to charge faster.
Plus I am pretty sure that if you charge at a voltage lower than the batteries suggested full voltage. (Say you charge the lithium cell with only a 3.8v power supply) I am pretty sure that you will never be able to fully charge it at that voltage, no matter what that other person claims. You cannot connect a 3.8v PSU to a lithium cell and just wait long enough and somehow find the cell at 4.2v.
What do you guys think? This only bothers me to see these peoples claims get best answers.
