Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.
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.
Smaller batteries are rated at a 1C discharge rate. Due to sluggish behavior, lead acid is rated at 0.2C (5h) and 0.05C (20h). While lead- and nickel-based batteries can be discharged at a high rate, the protection circuit prevents the Li-ion Energy Cell from discharging above 1C.
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.
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usually specify the depth of discharge (DOD) of a battery, which determines the fraction of power that can be withdrawn from it.
Discharging the same battery at 0.5C, or 500mA over 2 hours, will likely increase the capacity to above 100 percent. To obtain a reasonably good capacity reading, manufacturers commonly rate alkaline and lead acid batteries at a very low 0.05C, or a 20-hour discharge.
