The effective capacity under different high discharge current is an important parameter in designing UPS or even in electric vehicle.
The effective capacity of Lithium ion battery has a minor impact from high discharge current comparing to Lead-acid battery.
In the case of an UPS requiring high discharge rate CA, the effective capacity of Lead-acid battery can drop to less than half of the stated capacity. (CA defines the discharge current = Specified Capacity x 1A )
We have designed a simple calculator to estimate the effective capacity under different discharge current
