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 long does a 1C battery take to discharge?

For a battery with a capacity of 10 Ah, a 1C rate equates to a discharge current of 10 Amp. For a battery with a capacity of 1 Ah, discharging it at 1C rate means the discharging current is 1A. In both cases, discharge time will be the same, i.e., 1 hour. If the above batteries are discharged at a 2C rate, they will discharge within 30 minutes.

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.

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.
