Charging a battery with more mA than its genuine charger
The current available for charging will be limited by the output of the converter (i.e. if it supply 1A, the charger chip cannot charge the battery more than 1A), but if you replace a lower current wal-wart with a higher one, then the battery might be charged faster, however the charging current will still be limited by the charger chip -- whichever is lower, the AC adapter
batteries
When the battery is connected and tries to draw more than the set current, the charger will drop its voltage to limit current. At the same time the battery voltage will rise due to the charging current. When battery voltage reaches 8.4V the charger will progressively lower the charging current to prevent the voltage from going higher than 8.4V.

6 FAQs about [The more the battery is charged the greater the charging current]
What happens when a battery is fully charged?
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
What happens if you charge a lithium ion battery below voltage?

Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
Why is amperage important when charging a battery?
Amperage is the measure of electrical current, and it is critical to understand when charging a battery. A higher amperage will result in a cooler, steady power supply and shorter charge time, while a lower amperage can cause the charger to overheat.
How does state of charge affect battery charging current limit?
As the State of Charge (SOC) increases, the battery charging current limit decreases in steps. Additionally, we observe that the battery voltage increases linearly with SOC. Here, Open Circuit Voltage (OCV) = V Terminal when no load is connected to the battery. Battery Maximum Voltage Limit = OCV at the 100% SOC (full charge) = 400 V.
Why does a high amperage battery charge faster?
A higher amperage means the battery charges faster because it gets more energy in less time. Fast charging technologies often focus on increasing the amperage to reduce charging duration. This is handy when you need a charge in a hurry. But remember, each device has a limit.
Can a high amperage charge a battery?
A higher amperage results in a faster charging speed. But, batteries can only handle a certain amount of current. Going over this limit can harm the battery. How do I calculate charger watts? To calculate charger watts, multiply the charger’s voltage and amperage.
