Industry Will low voltage charge damage my battery? : r/TeslaModel3
You are probably conflating low "state of charge" with low charging rate/current. As others have commented, charging slowly (rate) is good for the battery. But having the battery discharged (empty) for a prolonged period is not good for it. Neither is having it fully charged to the max ("trip"/100%) routinely...

6 Frequently Asked Questions about “Why is the battery current low ”
What happens if a battery has a low voltage?
Voltage differences between cells can lead to decreased overall performance of the battery pack. During discharge, cells with lower voltage will limit the overall discharge voltage and capacity of the pack, reducing the total energy output. Voltage inconsistency can cause imbalance during charging and discharging.
Why does a battery have a higher voltage than a low voltage?
State of Charge (SOC): A fully charged battery will have a higher voltage than a battery that's running low. When you charge a battery, the voltage gradually increases until it reaches a safe maximum level. Temperature: Temperature can also play a role in battery voltage.
How does low battery voltage affect a car?
The Consumer Electronics Association states that low battery voltage directly affects the performance and efficiency of electrical systems. Recognizing these symptoms early can save vehicle owners time and money, allowing for timely interventions before more significant issues arise. How Does Temperature Affect Car Battery Voltage?
What happens if a car battery is low?
If the voltage falls to around 11.8 volts, the battery is in a state of discharged failure. Continuous operation at this low voltage can damage the battery, leading to premature failure. Additionally, extreme low levels, like 10.5 volts or lower, could prevent the engine from starting altogether.
Why do older batteries deliver lower voltages than new ones?
Internal Resistance: As a battery ages, its internal resistance increases, which can affect the voltage under load. This is one reason why older batteries tend to deliver lower voltages than newer ones. Part 3. Various types of voltage
Why does a battery drop ri?
Now remember, that a model for a battery is an ideal voltage source, internal resistance. when you start pulling current from the battery and complete the load there will be a voltage drop rI corresponding to the voltage drop due to the internal resistance this will cause the voltage of the cell to be lower than the voltage of the voltage source.
