6 FAQs about [Relationship between discharge current and battery ampere]

How does discharge rate affect battery capacity?

As the rate of discharge increases, the battery's available capacity decreases, approximately according to Peukert's law. Manufacturers specify the capacity of a battery at a specified discharge rate.

What is the relationship between battery voltage and battery energy capacity?

The relationship between the battery's average voltage, average discharge current and battery energy capacity can be seen in Figure 5. In terms of time it can be observed that the greater the load resistance value, the longer the battery discharge time.

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.

What is the difference between deep discharge and terminal voltage?

Depth of Discharge (DOD) (%) – The percentage of battery capacity that has been discharged expressed as a percentage of maximum capacity. A discharge to at least 80 % DOD is referred to as a deep discharge. Terminal Voltage (V) – The voltage between the battery terminals with load applied.

What is a maximum continuous discharge current?

Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. 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 many watts a battery can be discharged in one hour?
