I am preparing to test a battery-powered device and I am interested in determining its load on the battery. The load is periodic, but not constant, varying from about 11 watts to about 65 watts depending on what it is doing.
A web search for battery simulators located the Keithly 2302 and 2306 instruments. Does anyone have esperience with those, or can recommend a similar or better instrument?
I guess what I really need is a low-voltage DC watt-hour meter.
