What will stress a Li-ion battery more? High voltage or high current
The fact that it takes longer to charge must mean that the battery is pulling less current and thus also heating less. In battery terminology, the charger is what takes an input power source and generates the correct CC-CV (constant current, constant voltage) output to charge a li-ion battery. This charging circuit is often built into the device.

Current flow in batteries?
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.
Does a fully charged battery ''weigh'' more than an uncharged battery?
The stress-energy tensor (the source of gravitational attraction in General Relativity, our current best theory of gravity), is affected by the energy stored in a charged battery, and thus the charged battery is "pulled on" more strongly by the earth. However, the charged battery doesn''t have more MASS than an uncharged battery.

Will a depleted lithium ion battery burn/explode? : r/batteries
Incorrect, it depends on where you stabbed the battery more than anything and how "dead" the battery is. 2.7V, while most manufacturers label "dead" or cut off voltage can still deliver enough amps long enough to start a fire, more importantly shorting a battery causes the cell the expend the remaining power all at once.

6 FAQs about [Will the battery burn if charged with high current ]
What happens if a battery is discharged?
If a battery is discharged, it will give less intensity of current. - If we increase the voltage, the current intensity will automatically increase. In a car, everything that is connected to the battery is prepared to operate at a voltage of 12V. What would happen, therefore, if we could connect a 24V battery or 2 12V batteries in series?
How does voltage affect the current intensity of a battery?
Voltage: As the resistance of what we have connected to the battery is fixed, the higher voltage we have, the more current we can provide. Or put another way, the voltage will determine the current intensity and the higher the voltage, the more intensity we will give. - If a battery is discharged, it will give less intensity of current.
Do lead acid batteries explode when overcharged?
Explosions are a lot of fun. And here is an advertising video for safe sheds for charging lead acid batteries, and yes, they do explode when overcharged. Supposing that the charger gives the voltage greater than 12 V (say, 15 V), we can estimate 15 V × 100 A = 1500 W, a power of a small electric kettle.
Why is it dangerous to connect a battery to a cable?
For this reason, it is very dangerous to connect any current conducting element between the two battery terminals. Be careful, therefore, with connecting a direct cable, putting something metallic between the two terminals, or even spilling water on the battery. Intensity: It is the force that the battery can provide at all times.
What happens if you install a larger battery?

What happens if you double the voltage on a battery?
After all that has been seen, the answer is simple: if we double the voltage, the current intensity would also increase twice and we would run the risk of burning or damaging everything that is connected to the battery.
