Which battery works better? Alkaline, lithium, heavy duty, nickel cadmium, or nickel metal hydride?
I think that all the batteries will be the same.
I bought five different types of AA batteries. Two Alkaline, two lithium, two heavy duty, two nickel cadmium, and two nickel metal hydride.
I tested the batteries in five identical mini maglite flashlights, which run on two AAs each. They went on for an hour and then off for an hour. This repeated for nine hours. Then, to finish, they were left on for three hours.
I tested their milliamps (form of measurement) every hour on a multimeter. The experiment lasted for twelve hours.
