Most comments here are talking about “unreliable batteries” instead of proper battery charging/discharging and maintenance. Most of the time when things go wrong is due to overcharging.

That's on the manufacturer and/or regulators. A thing that needs to be plugged in in order to charge is never going to be perfectly babysat in the best of situations, and if it's a tool that people use everyday it's definitely got to be built so that it is safe if left plugged in for a month or if left unplugged and discharged for a month. If you can't get that worked out, you don't have a product that's safe to sell to the general public.

Define “safe for the general public”

If someone tried to save a couple dollars building a car and made one that you had to open the hood and disconnect the battery every time you were going to leave it parked overnight in order to prevent it from catching fire, that would be a car that's unsafe, the sale of which would never be allowed. If something has to be plugged in for hours, it needs to be safe to leave it plugged in for hours. Regardless of exactly when it stops charging. It's not that hard for manufacturers to build a battery and/or charging system that will shut off when it needs to so that it is safe.

The definition of safe for the general public for a given product may take a sentence or a book, but that's up to manufacturers and/or regulators to figure out and adjust for real world conditions. Clearly that's not happening.

Example: iPhones stop charging your phone when it hits 100% and when it hits 99%, it’ll charge to full and then stop.

That’s what battery charging tech should have by default

you could even have the battery's internal circuitry report 99% as 100% so the device is none the wiser and won't even try and shove more into it

That seemed like a pretty explicit definition for at least part of the requirement.

How can I learn about the proper way to do all of this?

FreedomCorn t1_iueyqbt wrote

Usually a manual or instructions. Sometimes called directions.

So all of these batteries come with these instructions and people are just not reading them?

Back in my LiPo RC car days, chargers had to go on timers so you didn’t come home to ashes and jail time. IIRC, nowadays you can buy a charger with variable output that has a built-in timer but they’re $$$$$. (That’s why all the cheap-China scooters don’t come with them built in, right?)

That's actually a good idea.

Except I don't know how common outlet timers are.

Overcharging is when you leave your charger on forever instead of charging the device and removing it from the charger when it’s done charging.
