Explanation of lead acid battery capacity

For example, the electric current commonly used in electric bicycles is 5A, and the battery using the nominal 10Ah is a 2-hour rate discharge. If a 10-hour rate discharge is used, it can reach 12Ah. Thus, if the battery is nominally 2 hours, it should be 10 Ah, if it is 10 Ah according to the 10 hour rate.

6 Frequently Asked Questions about “Battery 10-hour discharge rate current”

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.

What is a good battery discharge rate?

Battery manufacturers rate capacity of their batteries at very low rates of discharge, as they last longer and get higher readings that way. 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.

How long does it take a battery to fully discharge?

For example, a battery with a nominal capacity of 100 Ah (C 10 capacity for a 10hour discharge), when discharged with a 10 A current (C/10 rate) will take 10 hours to discharge the battery fully.

What is a 20 hour discharge rate?

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. For example, a battery rated at 1000mAh provides 1000mA for one hour if discharged at 1C rate.

What is the charge rate when a battery is halved?

When the discharging rate is halved (and the time it takes to discharge the battery is doubled to 20 hours), the battery capacity rises to Y. The discharge rate when discharging the battery in 10 hours is found by dividing the capacity by the time. Therefore, C/10 is the charge rate. This may also be written as 0.1C.

How do you determine the charging/discharging rate of a battery?

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 (in Ah) divided by the number of hours it takes to charge/discharge the battery.
