How to read battery discharge curves
Peukert''s law, presented by the German scientist Wilhelm Peukert [] in 1897, expresses approximately the change in capacity of rechargeable lead–acid batteries at different rates of discharge. As the rate of discharge increases, the battery''s available capacity decreases, approximately according to Peukert''s law.
The faster a lead-acid battery is discharged, the less capacity it has. While with lithium batteries this is not the case. For a Rebelcell 12V50, for example, C1=C5=C20=50Ah applies. The effective battery capacity therefore depends on how deep you can, and how

Calculator assumptions Lead-acid battery discharge efficiency rate: 85% Inverter efficiency: 90% How to use this calculator? Step 1: Enter the battery capacity and select the unit type.The unit types are amp-hours (Ah), and milliamp-hours (mAh). Step 2: Enter your battery voltage (V).
How long a battery lasts depends on the battery discharge rate. Understanding battery capacity can help you learn more about discharge rate. Peukert''s Law shows the battery discharge curve equation that describes the battery discharge rate. A battery discharge calculator also shows this.
While both types of batteries are lead-acid batteries, they differ in their construction and performance. In this article, ... Understanding AGM battery discharge rates is crucial for ensuring that your battery performs optimally and lasts as long as possible. In this ...
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 …

Lead-acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate …
It is recommended to discharge the battery at a rate of no more than 1C (where C is the battery''s rated capacity in ampere-hours). Optimal Discharging …
Peukert''s equation describes the relationship between battery capacity and discharge current for lead acid batteries. The relationship is known and widely used to this day. This ...

Battery Charging and Discharging Parameters
The end-of-discharge voltages vary for different types of batteries: approximately 1.75V/cell for lead-acid batteries, 1.0V/cell for NiCd/NiMH batteries, and 3.0V/cell for Li-ion batteries. By observing the time it takes for a battery to reach these specific voltages during the discharge process, the battery analyzer can calculate the …
By using a low discharge rate, such as 0.05C or a 20-hour discharge, the capacity of the lead acid battery can be measured under controlled and consistent conditions. This rating ensures that the battery''s performance is evaluated accurately and provides reliable information for users.
