The faster a battery can discharge, the higher its discharge rate. To calculate a battery’s discharge rate, simply divide the battery’s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps. The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA).
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.
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.
If a battery is being charged at 5 amps and has an energy rating of 20 Ah, the C rate is calculated as: \ [ C\ Rate = \frac {5} {20} = 0.25\ C \] This means the battery is being charged at a rate that is one-quarter of its total capacity per hour.
Formula: C-rate in time (minutes) = (1 ÷ C-rate) × 60 The chemistry of battery will determine the battery charge and discharge rate. For example, normally lead-acid batteries are designed to be charged and discharged in 20 hours. On the other hand, lithium-ion batteries can be charged or discharged in 2 hours.
To calculate a battery''s discharge rate, simply divide the battery''s capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery …
