  dont keep them on the charger constantly

  This is for the makita.

  Charge it to 100% then remove from charger. If you do no use it the battery will discharge over time. Charge it to 100% at least once a month through inactivity.

  Once it hits about 20-10% recharge on use charge it to 100% again. Depending on the cycle count of the battery it should last at least 2-3 years.

  For a phone, they make pretty resilient batteries nowadays, you should be able to charge it daily for at least 2-3 years with maybe 10% drop in battery performance.
  Usually once a phone hits 5 years old the battery is toast if recharged daily. It all depends on the battery cycles.

  I have had an ipod for about 20 years, and i charge it about once a week, the battery is about 50% now and still gives a good 2-3 hours playtime, with the original life being 5-6 hours. The quality of the battery can make a huge difference in how long it lasts. Usage helps maintain its life.

  Do modern batteries even need that much care to keep healthy?

    Yes and it depends on the battery chemistry as to how you keep the battery going for years if it is possible.

  Most of my lesser used lithium ion stuff I leave around 50-80%. I'm not that exact on it, partially because it's impossible to be on things like tool batteries which use 3 to 4 LEDs only. And others due to their design don't really have a choice, like Xiaomi robot vacuums I've tried leaving it off when not fully charged (still plenty to do the job) but then it auto powers off anyway and whatever else.

  I've only heard of lithium ions needing this though, not things like NiMH.

  Lithium batteries should be kept at around 40-50% State of Charge (Soc) but I am pretty content if mine sit somewhere between 20% and 80%

  Always keeping it at 100% will decrease its life and possibly kill it, and keeping it at 0% will kill it.

  Having said that, your device won't allow it to get to 0% most of the time, but you would be playing russian roulette if you then put a discharged battery into storage.

  Some devices once at 100% just bypass battery. Wish 2021 iPad Pro m1 did that. (Some posts say it does but I’m not convinced

    Some stop at 100% and then do not change again until they get below 90% or some other % in order to preserve the battery. I have no idea what devices do this. This way the batteries are not sitting their getting trickle charged.

  My makita 18V battery recently died even tho I barely used it so I was abit dissapointed (i still have 1 battery left)

  You can fix it if you still have one usable battery. I've followed the instructions given in this YouTube clip and it worked for me. https://youtu.be/GCMDtcmi1DQ

    Thanks! I have plenty of ozitos so will give a try!
    Need to get meself a multimeter

      I revived an Ozito for a family member. Battery that would throw error message on charger, after trickle charge from good, fully charged battery, charged normally and holds charge as normal.

  For phones, have the screen darkest as possible so it's black. You know when it's dark enough as the you won't know the difference between off/on.

  For other cordless devices, make sure the battery is removed and always plugged into the wall socket, so it's corded.

  Thanks for reading. Glad I could help 😂😭✌🏽

  Don't go below 30%
  Don't store above 80%

  that's what I follow.

  For lithium-ion, more important than the charge (although avoiding flat or near-flat is important) is the temperature the batteries are stored in.
  With power tool batteries, avoid keeping them in an outdoor shed that cooks in the sun.
  Similarly, Dyson will recommend not storing the stick vacuum cleaners in the garage as it's the hottest room in the house. My new V8 died that way after a couple of months and since then, mounted them indoors.
