Tired of your laptop battery degrading? New 'pulse current' charging process could double its lifespan.
Using pulse current charging, or a constant current divided with a few short breaks, lithium-ion batteries hold up better over hundreds of charging cycles and can last twice as long.
In 2023, Josefin Strandberg, professor of particle physics at the KTH Royal Institute of Technology in Sweden, published a paper that found lithium-ion battery health improved when using a pulse current-based charging protocol. He has written for a variety of publications including ITPro, The Week Digital, ComputerActive, The Independent, The Observer, Metro and TechRadar Pro. He has worked as a technology journalist for more than five years, having previously held the role of features editor with ITPro.
