Occasionally lithium battery cells are marketed with just a C rating and not a maximum current rating. This can make it easier to compare the power level of battery cells of different capacities. As long as you know the capacity of the cell, you can use the C rate to quickly calculate the maximum current rating of the cell.
The capacity of a cell is probably the most critical factor, as it determines how much energy is available in the cell. The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh. Lithium battery cells can have anywhere from a few mAh to 100 Ah.
A: 3.7V is a rated voltage of lithium battery and the max charging voltage is 4.2V. The nominal voltages of 3.7V and 4.2V are equivalent when it comes to size and capacity.3.7V battery can replace a 4.2V battery.
The nominal voltage is distinguished from differen li ion battery models.For example, when a device is marked with”3.7V lithium-ion battery,” it’s referring to the nominal voltage of 18650 cells. When an 18650 battery is fully charged, its voltage reaches approximately 4.2V. It is the maximum safe voltage of standard 18650 cells.
The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh. Lithium battery cells can have anywhere from a few mAh to 100 Ah. Occasionally the unit watt-hour (Wh) will be listed on a cell instead of the amp-hour. Watt-hour is another unit of energy, but also consider voltage.
The maximum current a battery can safely provide is dictated by its discharge rate, which is linked to its ampere capacity. For a typical 18650 battery, the discharge rate could range between 15 to 30 amps. High-drain batteries intended for demanding applications can even exceed this range.
What is the maximum current which can pass in a Li_ion battery?
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA.

Understanding 18650 Battery Voltage: From Basic to Advanced
When an 18650 battery is fully charged, its voltage reaches approximately 4.2V. It is the maximum safe voltage of standard 18650 cells. The discharge cutoff voltage, known as the low voltage limit, is around 2.0V to 2.5V for 18650 batteries. This voltage should be considered as "empty" and the 18650 batteries should be charged.
