Max Discharge Current (7 Min.) = 7.5 A Max Short-Duration Discharge Current (10 Sec.) = 25.0 A This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.

READ MOREA smart battery may require a 15 percent discharge after charge to qualify for a discharge cycle; anything less is not counted as a cycle. A battery in a satellite has a typical DoD of 30–40 percent before the batteries are recharged during the satellite day. A new EV battery may only charge to 80 percent and discharge to 30 percent.
READ MOREThis battery is almost similar to the Ni-Cd battery. The nominal voltage for the Ni-MH battery is 1.2V for a single cell.

READ MOREYou 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.

Pb (Lead Acid) After the discharge process completes, rotate the button to view the real-time battery voltage every 30 seconds for the first six minutes.
READ MOREA battery is an electrical component that is designed to store electrical charge (or in other words - electric current) within it. Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge.
READ MOREBattery discharge considers the two mechanisms defined above: a combination of alleviation of demand-intense periods and an arbitrage strategy. Thus, the reward values depend on the variable χ (defined as the ratio between the hourly imported power and the maximum hourly imported power registered throughout the day) and the time-varying cost
READ MORECalculating Discharge Rate. You can use Peukert''s law to determine the discharge rate of a battery. Peukert''s Law is. t=Hbigg (frac {C} {IH}bigg)^k t = H (I H C)k. in which H is the rated discharge time in hours, C is the rated capacity of the discharge rate in amp-hours (also called the AH amp-hour rating), I is the discharge current in
READ MOREA 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
READ MOREManual discharge techniques involve connecting an external load to the battery to drain its charge. This can be done using a battery discharger or any other load that is suitable for the battery''s specifications. The load current should be monitored to prevent over-discharging and damage to the battery.
READ MOREThe discharge current may alternatively be expressed as a multiple of the rated discharge current. For example, if the batt ery is specified at the 10 hour rate, I 10 = C/10 (Ah/h) and is the current which would discharge the battery in 10 hours. Then, if C = 40 Ah, I 10 = 40/10 = 4 A and a current of 10 A can be written as 2.5 I 10.
READ MOREIf the capacity did not depend on the discharge current, we would expect the test current for a 5h test to be twice as high (32.8 A). However, in this case, the C/5 test current is slightly lower at 30.9 A. The nominal capacity of a battery is usually shown in Ampere hours for a certain C-rate, for example, 100 Ah/ C10.
