The current required to charge a lithium-ion battery can vary significantly. While the traditional guideline is to charge at a rate of 0.5C to 1C (where C is the battery’s capacity), many lithium-ion batteries can safely be charged at much higher rates. Why the Preference for Higher Charging Current in Lithium-ion Batteries?
This is the recommended current value of what is written on your photo above. The current less than 10% requires more time to charge. But it is admissible. A current of more than 25% of capacity can heat the battery, which leads to a decrease in service life ..
Factors like battery type, capacity, and state of charge influence how much current is needed to charge a 12V battery. Generally, the charging current for a 12V battery is around 10% of the battery’s capacity.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
For deep-cycle batteries, a general rule of thumb is to charge at 10-13% of the battery’s 20-hour capacity rating. For instance, a 100Ah deep-cycle battery would require a charging current of 10-13A. Imagine you're charging a battery, and it's kind of like filling up a water balloon.
An 800 ampere-hour battery typically can deliver about 9,000A into a short circuit. The magnitude of short-circuit current at the point of fault in the battery circuit depends on the battery's internal resistance and the external circuit resistance. Often, the peak short-circuit current occurs within 5 to 15 milliseconds.

Cell phone batteries are small and can produce the current your looking for. Coin and button batteries are designed for quite small current draw. We know you need 5 volts at 500 mA. There are (at least) two important figures left out. How long must it run on battery power, and just how small is the allowable space? Is weight a factor?
Understanding the Current Requirement for Charging a 12V Battery
Generally, the charging current for a 12V battery is around 10% of the battery''s capacity. Charging current can vary based on battery type; lead-acid batteries are generally charged at a rate of 10% of their capacity, while lithium-ion batteries can handle higher charging currents, sometimes up to 100% of their capacity.
