What happens if a battery is discharged after removing a load?
When removing the load after discharge, the voltage of a healthy battery gradually recovers and rises towards the nominal voltage. Differences in the affinity of metals in the electrodes produce this voltage potential even when the battery is empty. A parasitic load or high self-discharge prevents voltage recovery.
What is the difference between amperage and discharge rate?
Current Flow: Amperage represents the rate electric charges pass through a conductor. A higher amperage indicates a greater flow of electricity. Battery Discharge Rate: A battery’s discharge rate is often expressed in terms of C-rates, which indicate how quickly a battery can be discharged relative to its capacity.
What is a discharge curve in a battery?
The discharge curve is a plot of voltage against percentage of capacity discharged. A flat discharge curve is desirable as this means that the voltage remains constant as the battery is used up. 4) Capacity The theoretical capacity of a battery is the quantity of electricity involved in the electro-chemical reaction.
How long can a battery be discharged?
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.
How much does a high discharge current affect battery capacity?
With a higher discharge current, of say 40A, the capacity might fall to 400Ah. In other words, by increasing the discharge current by a factor of about 7, the overall capacity of the battery has fallen by 33%. It is very important to look at the capacity of the battery in Ah and the discharge current in A.
Should a battery be fully discharged before charging?
For example, nickel cadmium batteries should be nearly completely discharged before charging, while lead acid batteries should never be fully discharged. Furthermore, the voltage and current during the charge cycle will be different for each type of battery.
