Understanding Charge-Discharge Curves of Li-ion Cells
C-Rate of discharge is a measure of the rate at which the battery is being discharged when compared to its rated capacity. A C/2 or 0.5C rate means that this particular discharge current will discharge the battery in 2 hours. For example, a 50Ah battery will discharge at 25A for 2 hours. A similar analogy applies to the C-rate of charge.

Battery Charging and Discharging Parameters
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity

Battery Discharge Time Calculator
Battery discharge time can be calculated using the formula: Discharge Time = Battery Capacity (in amp-hours) / Load Current (in amps). How long will a 155Wh battery last? To determine the time, you need to know the load current. If the load uses 100W (155Wh), and assuming 12V, the discharge time would be around 155Wh / 100W = 1.55 hours.

What is battery discharge time?
Battery discharge time is the duration a fully charged battery can power a device before needing a recharge. Factors like battery capacity, power consumption, and usage patterns affect discharge time. Knowing how to calculate and optimize battery discharge time is key to getting the most from your devices.
How do you calculate battery discharge time?
Use the formula: Discharge Time = Battery Capacity (Ah) / Load Current (A). This method considers the battery's capacity and the device's power use. It tells you how long the battery will last before needing a recharge.
What is a battery discharge rate?
Discharge Rate: This is how fast the battery loses its charge. It can be changed by things like how you use your device, the temperature, and the battery's age. Put these numbers into the formula to find out the battery run time or battery discharge time for your device.
What is a 20 hour battery discharge rate?
This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.
How does discharge rate affect battery capacity?
As the discharge rate ( Load) increases the battery capacity decereases. This is to say if you dischage in low current the battery will give you more capacity or longer discharge . For charging calculate the Ah discharged plus 20% of the Ah discharged if its a gel battery. The result is the total Ah you will feed in to fully recharge.
Can a battery be fully discharged?
In many types of batteries, the battery cannot be fully discharged without causing serious, and often irreparable, damage to the battery. Manufacturers usually specify the depth of discharge (DOD) of a battery, which determines the fraction of power that can be withdrawn from it.
