6 Frequently Asked Questions about “How to check the maximum current of the battery”
How do you know if a battery has a Max discharge current?
There is no generic answer to this. You 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.
How do you calculate the voltage of a battery?
1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.
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.
What is a good battery capacity?
If it lists the capacity as 50Ah at C/20 (common for lead-acid), that's 2.5A so you might want a better battery. EDT as Andy says, if your device draws bursts of higher current, you also need to know the max (not continuous, maybe called peak) discharge current of your battery matches whatever your load needs.
Do batteries have a max current drain?
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
How much current does a battery need for 1 hour?
If your product requires 4.6 Ah for 1 hour then all you can say is that the average current your product requires is 4.6 amps. This is the average and not the peak. The peaks may be very large (circa 10 amps) but may only last for sub milliseconds in time. If you have reasonable capacitance on your circuit the battery may not see these peaks.
