minus-squarejacksilver@lemmy.worldlinkfedilinkEnglisharrow-up0·10 days agoOddly enough I do actually think a charged battery is heavier, just as a full hard drive is heavier. But not to a degree that would matter. https://toolsweek.com/do-batteries-weigh-more-when-charged/
minus-squareColeSloth@discuss.tchncs.delinkfedilinkEnglisharrow-up1·10 days agoThat article you linked is utter trash, but it is correct about battery weight of a charged battery…technically…very technically…barely. Like, a 4,000 mah lithium battery fully charged should weigh about 30 picograms more than when dead. To put 30 picograms into perspective; a single 5 inch long human hair weighs around 0.04 grams. Well that’s 40,000,000,000 picograms.
