🔋 Battery advice is a mess.
Never charge past 80%. Always keep it above 20%. Never leave it plugged in overnight. Fast charging destroys your battery. Rechargeable AAs explode.
So... which of these are actually true?
In this episode, Caya goes down the battery rabbit hole to uncover where all these rules came from. We trace the evolution of batteries—from Zinc-Carbon and Alkaline cells to lead-acid car batteries, Nickel-Cadmium, and modern Lithium-ion packs—to separate real science from decades of outdated advice and internet myths.
Along the way, we'll explain why some batteries really can explode, why power banks are restricted on airplanes, where the infamous "20–80%" rule comes from, whether fast charging actually damages your battery, and why different generations of batteries created completely different "rules" that people still repeat today.
Because battery myths...
didn't come from nowhere.
They're leftovers from technologies that most of us don't even use anymore.
