PLEASE USE THIS CALCULATOR TO DETERMINE THE Ah RATING
OF THE BATTERY REQUIRED.   

How long will device be used? 


* Required
 

Result: Amp Hours 
Needed
Note: If the discharge profile changes, each must be calculated separately and then added together.
For example: If a device discharges with a small background for 30 days and then the device starts a pulse discharge for another 30 days, you must calculate this as 2 separate discharges.  The results of both discharges are then added together.
