ELI5: How do battery charge level indicators work?
In that vein, most devices don''t run at only a specific voltage, but rather a range of voltages, in order to ensure that the battery can power the device as long as possible. So the battery charge indicator is just taking the measured voltage supplied by the battery, comparing it to the expected, and then displaying it as a percentage.
Tested: Should You Unplug Chargers

How hot should the batteries get while charging?
The image below shows a situation near the end of the charge with SoC ~97%. The charge power into the battery was ~11kw and the cell temperatures were ~53°C (which seems pretty hot to me), but the car was still trying to HEAT the battery. It was pouring 3.5kW into each of the front and rear motors, with a reported stator temperature of 130°C
i have a question, it''s always said that charging phone 20-80
You charging at the 50% mark might actually be closer to the 60% mark. According again to Battery University, 40% depth of discharge (100 drain to 60% before charging) on a 600 cycle battery actually bumps the number of cycles to 3000 cycles. That''s a 5x increase. So charging a phone at 50% might bump the 1000 cycles up to 5x thanks to BMS.

Moreover, repeated attempts to start the car with a weak battery can result in additional wear on the battery and starter motor. Do you have to charge a new car battery
ELI5: How does charging a phone beyond 80% decrease the battery
My understanding is that that''s what most charging blocks do. They have circuitry that stops charging at a certain point to keep from turning your battery into a small explosive. But, even just charging to, say, 80% still comes with some wear and tear. Just less of it than charging to 100% or overcharging.
What happens to a fully charged battery, when you continue to charge
Once the battery is full, the charging circuit stops drawing power from the charger until such a point where it decids to resume charging. Assuming a properly functioning charging circuit you cant add excess energy to the battery. There is no redirrcting of energy, the chaarging circuit just stops drawing power from the charger.

A battery charger requires an external power source to provide the electricity needed to replenish a battery''s energy. A battery charger connects to an electrical outlet, allowing it to draw power.
Why does keeping lithium-ion batteries at a 100% charge
Now if you could magically tell the charger circuit "charge to 80%, and then draw power from the charger without touching the battery" - this would indeed be optimal. Just don''t try and do this by plugging/unplugging. In short - let your battery get to 100%, sit at 100%, and don''t care.
Does battery condition have anything to do with macbook pro

6 FAQs about [Does charging power have anything to do with battery ]
How does battery charging work?
Battery charging adds electrical energy to a battery, allowing it to store energy for future use. A device known as a battery charger facilitates this process. Connecting your device to a charger supplies an electrical current that reverses the chemical reactions when the battery discharges.
How much energy does a battery charger use?
While it can vary depending on the specific charger and battery being used, on average, charging a battery for an hour uses around 20-25 watt-hours of energy. In comparison, a refrigerator can use anywhere from 100 to 150 watts per hour, while an air conditioner can use upwards of 1000 watts per hour.
Does charging a car battery use a lot of electricity?
Fast charging electric vehicles, on the other hand, can use a lot more electricity, sometimes up to 150 kW or more per hour. Overall, charging a car battery isn’t as energy-intensive as some other activities, but it still consumes a significant amount of electricity, especially if it’s done frequently.
Can a battery be charged without a voltage difference?
Well, to push in charges into anything, you need a voltage difference. So, yes. Generally: You usually don't charge batteries just by connecting them to an uncontrolled voltage source. The correct method for charging a battery depends fully on its type, its current charge status and usage scenario.
Can a fast charger charge a malfunctioning battery?
To securely charge a malfunctioning battery, most rapid chargers integrate temperature sensors. The fast charger has various benefits, the most prominent of which is faster charging times. This necessitates more frequent contact between the charger and the battery.
How does a battery charge and discharge?
During discharge, electrons flow from the anode to the cathode through an external circuit. Electrolyte: This medium allows ions to move between the electrodes during charging and discharging. Charger: The charger provides the voltage and current to replenish the battery’s energy.
