A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
For example, a battery cabinet contains 16 pcs of 12V battery, and all of them connect in series, the nominal voltage of this battery cabinet is 192Vdc. It would match the UPS which should connect 16 pcs of battery, battery voltage 192Vdc or charging voltage 218.4.
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
Ambient temperature The rated capacity of a battery is based on an ambient temperature of 25°C (77°F). It’s important to realize that any variation from this operating temperature can alter the battery’s performance and shorten its expected life.
The amount of current a battery can supply is determined by several factors. The first factor is the battery’s voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
Most battery datasheets show “Maximum Charge Current”, usually it’s around 0.3C. For normal operation, charging current is 0.1C as the best practice. It’s never less than 0.05C. C rate is the rate of the charging/discharging current over battery capacity. 1C means one hour charge, that is to charge an empty battery to full in one hour.

voltage
$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).

How many currents Can a Battery Supply & How Batteries are …
How much current a battery can supply depends on the type of battery. A lead acid battery can provide up to 2,000 amperes (A) of current while a lithium-ion battery can only provide about 700 A. The amount of current that a battery can provide also decreases as the temperature gets colder.

Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?
