An equation/model that described the effects of time, current, temperature, etc. on battery voltage would be very useful. It would be even better if a microcontroller could use that model to deduce/estimate the internal state of the battery -- in particular, the state of charge (SoC) and the depth of discharge (DoD).

Alkaline battery

Alkalines have a high internal resistance, and a high thermal coefficient of resistivity - the faster an alkaline battery is drained, the higher percentage of the load it dissipates as heat. Therefore, the capacity of an alkaline battery is strongly dependent on the load, even at moderate loads. A AA-sized alkaline battery might have an effective capacity of 3000 mAh at low power, but at a

6 FAQs about [Alkaline batteries charge at high currents]

What is the voltage of a new alkaline battery?

The actual zero-load voltage of a new alkaline battery ranges from 1.50 to 1.65 V, depending on the purity of the manganese dioxide used and the contents of zinc oxide in the electrolyte. The voltage delivered to a load decreases as the current drawn increases and as the cell discharges.

Why are aqueous alkaline batteries important?

The ongoing surge in demand for energy conversion and storage spurs the development of high-efficiency batteries. In recent decades, aqueous alkaline batteries (AABs) have been the focus point owing to the high safety, low cost, environmental benefits, impressive output voltage and theoretical energy density.

Which alkaline battery has the highest power density?

As a proof of the application feasibility, the alkaline battery assembled with the as-prepared Bi-200 anode and NiCo 2 O 4 cathode presented a highest energy density of 85.8 Wh kg −1, a peak power density of 21.2 kW kg −1 and superior cyclic stability with a 89% capacity retention over 1000 cycles .

What is the capacity of an alkaline battery?

The capacity of an alkaline battery is strongly dependent on the load. An AA -sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh.

What is an alkaline battery?

The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4 Cl) or zinc chloride (ZnCl 2) electrolyte of the zinc–carbon batteries. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.
