Understanding Battery Technical Specifications.

This is the "energy capacity" of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage. Energy is calculated by multiplying the discharge power (in Watts) by the discharge time (in hours).

C Rating Calculator

What is C rating Calculated. C Rating is a fairly misunderstood concept in batteries. The C Rating is defined by the rate of time it takes to charge or discharge a battery. You can increase or decrease the rate which in turn will have an inverse effect on the time it takes to charge or discharge the battery.

How to Measure Battery Capacity

Battery capacity is typically measured in units such as Ampere-Hours (Ah) and Watt-Hours (Wh). If measuring via AH, it represents the number of amperes of current a battery can deliver over the span of one hour. Theoretically, a 100Ah battery should be able to deliver 100 amperes in 1 hour before being completely discharged.
