Customer ServiceYou should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is mentioned is 1000 mA = 1 A. That does not mean you cannot discharge with 2 A but realize that the battery''s capacity will be less at such a high current.

Customer ServiceThe nominal voltage is the average voltage of the battery over its discharge cycle, while the maximum voltage is the highest voltage that the battery can reach when fully charged. For example, the 18650 batteries used by Tesla have a nominal voltage of 3.8 volts and a range of 3.3 to 4.2 volts, and a 17 amp maximum discharge current.
Customer ServiceThe capability to sustain high charge or discharge rates depends on the battery''s chemistry and construction. This calculator provides a simple tool for calculating the C rate of batteries, making it easier to manage and optimize battery use in various applications.
Customer ServiceThis article contains online calculators that can work out the discharge times for a specified discharge current using battery capacity, the capacity rating (i.e. 20-hour rating, 100-hour rating etc) and Peukert''s exponent.
Customer ServiceFor a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E-rate describes the discharge power. A 1E rate is the discharge power to
Customer ServiceThe battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage. The capacity is
Customer ServiceStandard Charge/discharge current: 0.5C/0.5C; Operating Voltage: 2.5V~3.65V; Maximum continuous charge/discharge current: 1C/1C; Maximum pulse charge/discharge current(30s): 2C/2C ; 100Ah Lithium battery cell. As we can see, the standard charge/discharge current is 0.5C. Now, what is C? C stands for C-rate. To know more about C-rate, I

Customer ServiceThe battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery
Customer ServiceThe maximum continuous discharge current is the highest amperage your lithium battery should be operated at perpetually. This may be a new term that''s not part of your battery vocabulary because it is rarely if ever, mentioned with lead-acid batteries. RELiON batteries are lithium iron phosphate, or LiFePO4, chemistry which is the safest of all lithium chemistries.
Customer ServiceHowever, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery. For example, a battery capacity of 500 Ah that is
Customer ServiceAn example of this is if a battery amperage is 2000mAh or 2Ah and has a 1C rate, then it will take 60mins to charge or discharge the battery. 1C rating is the base time which is always equivalent to 1 hour or 60mins. The C Rating''s charge or discharge time changes proportionally to the rating. 1C is equal to 60mins, 2C is equivalent to 0.5h or 30mins and a 0.5C rating is equivalent to 2h
Customer ServiceFor a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for this battery would be 500 Amps, and a C/2 rate would be 50 Amps. Similarly, an E
Customer ServiceDischarge current, as well as charging current, is usually expressed as a C-rate. A current required for a 1-hour discharge is described as 1C, a 2-hour discharge is C/2 or 0.5C and a 10-hour discharge is C/10 or
Customer ServiceIn 1897 a German physicist, W. Peukert, determined that the capacity of a lead–acid battery depends on the discharge rate of the battery, saying that high discharge rates decrease the storage capacity by a predictable factor.
Customer ServiceDischarge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
Customer ServiceThe following figure illustrates how a typical lead-acid battery behaves at different discharge currents. In this example, the battery capacity in Ah, is specified at the 20 hour rate, i.e. for a steady discharge (constant current) lasting 20 hours. The discharge current, in amps (A), is expressed as a fraction of the numerical value of C.

Customer ServiceA battery''s charge and discharge rates are controlled by battery C Rates. The battery C Rating is the measurement of current in which a battery is charged and discharged at. The capacity of a battery is generally rated and labelled at the 1C Rate (1C current), this means a fully charged battery with a capacity of 10Ah should be able to provide 10 Amps for one hour. That same
Customer ServiceConverting the C rate of your battery into amps will give you the recommended charge and discharge current (amps). Formula: Battery charge and discharge rate in amps = Battery capacity (Ah) × C-rate. let''s say you have a 100ah lead-acid battery. 100Ah lead-acid battery has a recommended charge and discharge rate of 5 amps.
Customer ServiceBatteries have an inherent limitation as to the number of times they can be discharged and recharged, and you have seen that this can be reduced by excessive temperatures and depth of discharge. However, some modern technologies are now promoting 10 000 cycles of lifespan, whereas most current technologies are proud to reach 1000 cycles, with
Customer ServiceDischarge current, as well as charging current, is usually expressed as a C-rate. A current required for a 1-hour discharge is described as 1C, a 2-hour discharge is C/2 or 0.5C and a 10-hour discharge is C/10 or 0.1C. The table below shows the discharge times for
Customer ServiceThis is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity. For example, a battery rated at 1000mAh
Customer ServiceYou read the battery datasheet. Either it will tell you the max discharge current, or it will tell you the capacity at a particular discharge rate, probably in the form C/20 where C means the capacity. You know the current you need : 4.61A. If the battery data lists a continuous discharge current of 5A or more, you are good.
Customer ServiceThe battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
Note that the highest discharge current that is mentioned is 1000 mA = 1 A. That does not mean you cannot discharge with 2 A but realize that the battery's capacity will be less at such a high current. You will get less energy out of the battery compared to a more realistic discharge current of for example 100 mA.
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
The discharge rate is usually expressed in terms of amperes (A) or milliamperes (mA). For example, a common AA battery has a discharge rate of about 2.4 A. That means that it can provide 2.4 A of current for one hour, or 1.2 A for two hours before it needs to be recharged.
This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.
In many types of batteries, the battery cannot be fully discharged without causing serious, and often irreparable, damage to the battery. Manufacturers usually specify the depth of discharge (DOD) of a battery, which determines the fraction of power that can be withdrawn from it.
