[Education] What Is The Difference Between Amp-Hours (Ah) And Continuous Amperage Discharge (A) For My Batteries?

A V-Mount or Gold Mount (3-Stud) battery often has an Amp-Hours or Ah specification. This is another way of writing Watt-Hours or Wh, which is commonly how people measure the capacity of their batteries.

For our high-powered LED lights, we recommend batteries that are capable of delivering at least 14-15 Amp continuous discharge for best results, and battery longevity. The discharge rate measures how much energy a battery is capable of transferring from itself, to whichever device is drawing power from it. Higher wattage devices require higher discharge rates.

Amp-Hours (Ah) should not be confused with the discharge rate. For example, a 14.4V 310Wh battery has roughly 21Ah of capacity. However, the battery may only be capable of continuously discharging 15A.
