So to help you prolong and maximize the lifespan of your laptop, cell phone, or other electronic that uses a li-ion batteries (like an electric shaver)… I’ll teach you what causes a lithium-ion battery to age prematurely …PLUS, tips, tricks, and crucial maintenance information you must know to get the most out of your Li-ion batteries. So… How Does A Lithium-Ion Battery Work? Lithium-ion batteries work based on ion movement between negative and positive electrodes.Theoretically, lithium-ion batteries should work forever. However, high temperatures and cycling decreases their lifespan over time View our Free Presentation to learn how to bring old batteries back to life again
