Besides the different chemical compositions of the two battery types, lithium batteries have a higher energy density and voltage than alkaline batteries, ranging from 1.5 volts (for lithium iron ...

power-hungry devices like digital cameras and other items that would otherwise require a disposable alkaline battery (also 1.5V) to meet their voltage needs. Li-ion batteries also require ...

As for voltage, an LR44 has a nominal voltage ... AG13 and A76 are the same type of battery as an LR44, alkaline to be specific. These batteries use zinc oxide and manganese dioxide to generate ...

They provide a higher voltage output ... giving them an edge over alkaline batteries. The weight of the battery is also a significant factor, especially for portable electronics.

Here at CNET, we've put a wide range of alkaline batteries through our testing ... we conducted discharge tests and calculated the cost per battery to help you get the best bang for your buck.

But the inability for traditional NiMH (nickel metal hydride) batteries to reach the voltage of a single-use alkaline battery at 1.5V or even maintain their 1.2V level for the operating life of the ...

A battery's voltage is determined by the potential difference between ... Zinc-air batteries commonly used in hearing aids theoretically have a voltage of 1.9 V thanks to strong alkaline electrolytes.

And now a research group has done just that, realizing a zinc-air battery with an open circuit voltage of over 2 V. "We harnessed a cell with a rare-metal-free cathode and acidic/alkaline ...
