Martyr I (Zinc Anodes)	Martyr II (Aluminum Anodes)
355 Ampere hours per pound	1225 Ampere hours per pound
This means a Zinc anode will give one amp for 355 hours for every pound of Zinc	This means an Aluminum anode will give one amp for 1225 hours for every pound of Aluminum
Take a typical Z3 (weight=4.68 kg)	Take a typical AZ3 (weight = 2.7 kg)
Total ampere hours 3656	Total ampere hours 6125
Assuming the anode performs at 0.5 amp	Assuming the anode performs at 0.5 amp
This anode will last for 7312 hours	This anode will last for 12250 hours
Which is 304 days / 10 months	Which is 510 days / 16.5 months
