How fast can a AA battery discharge?
Your math is off: A high quality AA cell has about 3000mAh, which gives you about 10,000 hours run time, or a bit more than one year. But the discharge voltage will drop quickly lower than 3,0V – end voltage is about 0.9V/cell. I would expect the drop from 3.2 to 3.0V to occur within one or at most two weeks.
What is the discharge rate of a AA battery?
Its more regular voltage provides better drop-in compatibility for alkaline AA devices, and its lithium-ion chemistry provides a lower self-discharge at 3% per month. It holds a mediocre capacity of 1600 mAh (1.5 V) at 50 mA drain, limited by the low efficiency of the step-down converter.
What is the longest lasting AA alkaline battery?
Energizer Ultimate Lithium
Energizer Ultimate Lithium is officially the Longest-lasting AA battery!
What voltage is a dead AA battery?
AA batteries start off with 1.5 volts of energy, but the voltage goes down as the batteries are used up. Once the batteries dip below 1.35 volts, they appear to be dead, even though they still have a lot of juice left.
What is the discharge rate of an alkaline battery?

What’s the maximum current draw for an AA battery?
Re: Maximum AA battery current draw? The Energizer specifications for AA cells only rate them to the range of 0.5 to 1.0 amps maximum and the discharge voltage drop may limit the output to only 0.8 volts so I think that answers your question. The voltage sag of the alkaline cells is limiting the power your regulator can provide.
Which is the best discharge test for AA batteries?
3. I am using a CBA II computerized battery analyzer. This is reliable only above 100 mA, so the discharge tests below are for relatively high currents, in other words digital cameras. The performance rankings may be different for low current applications.
What is the resistance of an alkaline battery?
The typical effective resistance of fresh Energizer® alkaline cylindrical batteries (using a 5 mA stabilization drain followed by a 505 mA 100 millisecond pulse) will be approximately 150 to 300 milliohms, depending on size.
