Batteries were set up on a measurement jig to simulate near maximum load on the VK3YNG MK4 foxhunt sniffer. (Continuous signal, Range=0, daytime operation, Internal speaker volume setting = 8)

Batteries were wired two in series into a load of 50 ohms terminated in a voltage of -5V. This represents a load of 160mA at 3 volts and approximately 150mA at 2.5 volts.

Batteries were purchased at similar times from supermarkets and specialty shops in June 2002. Source files are available.

*Cost is based on two batteries and is in Australian Dollars. $/Hr rating can improve if batteries are purchased in bulk packs. Note that the Digitor batteries were purchased from Dick Smith Electronics in a 40 piece bulk pack, whereas most of the other batteries are purchased on two or four battery packs, whichever was the minimum available. Pricing is therefore not fairly compared for the Digitor batteries, but regardless of this their performance figures are very good.
