How much is the discharge rate of lead-acid battery

For a battery with a capacity of 100Ah, this equates to a discharge current of 100A. A 5C rate for this battery would be 500A for 12 minutes (1/5 hours), and a C5 rate would be 20A for 5 hours. There are two ways of expressing the C rating of a battery. Either with a number before the C or with a number after the C. For example:

How fast should a lead acid battery be discharged?

The faster you discharge a lead acid battery the less energy you get (C-rating) Recommended discharge rate (C-rating) for lead acid batteries is between 0.2C (5h) to 0.05C (20h). Look at the manufacturer’s specs sheet to be sure. Formula to calculate the c-rating: C-rating (hour) = 1 ÷ C

What is the discharge rate of a lead-acid battery?

Sealed lead-acid batteries are generally rated with a 20-hour discharge rate. That is the current that the battery can provide in 20 hours discharged to a final voltage of 1.75 volts per second at a temperature of 25 degrees Celsius.

What is the ideal discharge curve of a lead acid battery?

The ideal discharge curve of a lead acid battery is on a flat discharge curve, the amount of current that the battery can deliver remain more or less constant for quite a while and then drop off rapidly when the limit of it capacity has been reach.

What is the charge and discharge rate of a battery?

Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.

How many Ah can a lead acid battery deliver?

A lead acid battery is rated at 100Ah at C20, this means that this battery can deliver a total current of 100A over 20 hours at a rate of 5A per hour. C20 = 100Ah (5 x 20 = 100). When the same 100Ah battery is discharged completely in two hours, its capacity is greatly reduced. Because of the higher rate of discharge, it may only give C2 = 56Ah.

What is the discharge rate of a lithium ion battery?

Smaller batteries are rated at a 1C discharge rate. Due to sluggish behavior, lead acid is rated at 0.2C (5h) and 0.05C (20h). While lead- and nickel-based batteries can be discharged at a high rate, the protection circuit prevents the Li-ion Energy Cell from discharging above 1C.

There are two ways of expressing the C rating of a battery. Either with a number before the C or with a number after the C. For example:

How do I calculate the self discharge rate of a lead acid battery?

There is no doubt that you will get some sort of battery in each case, but as the capacity you achieve will be lower at best and probably much lower, then a long self discharge life may not return a better net capacity that a standard lead acid battery for at least 12 months. After 12 months you MAY get more capacity than std lead acid. But certainly not certain.
