Recently i bought a laptop with my friend. So, i went home charged it fully and begun to use it. However, my friend informed me that Acer recommends users to charge and deplete battery up to 3times.https://sg.answers.acer.com/app/answers/detail/a_id/27666 [Broken] I was confused over this. Shouldn't the threshold of the battery's lifespan be based on the voltage/potential difference that the battery can withstand along with the current output. Afterall, we are simply reversing the current flow when using the battery in respect to charging. Am i getting the purpose of the charging-depleting wrong or missing something out? P.S. How to insert a picture on this forum? Also, sorry if i posted this forum on the wrong sub-forum, am new to the forum.
