Current draw of Dewalt DCL060 20V Max LED Worklight

I recently purchased a Dewalt DCL060 area worklight and decided to measure the current draw so I could calculate the rough battery lifetime. With a lab PSU set to 18V which is the nominal voltage the current draw was 1.37A. Here’s a table of roughly how long it will last for the common battery capacities that I know of:

Capacity (Ah)   Battery life (hours)
1.3		0.9
2		1.5
3		2.2
4		2.9
5		3.6
6		4.4
9		6.6
