Alkaline Vs Lithium Battery Power

Alkaline Vs. Lithium Battery Power


Lithium and alkaline batteries are the most dominant forms of portable energy for consumer electronics. Both are generally designed to run at the same voltage and can be used in the same applications if put in a AA, AAA or 9V housing. However, companies may design proprietary batteries for particular products.


Alkaline Batteries








Alkaline batteries are disposable batteries that use a zinc anode and a manganese oxide cathode to create electric power. They come in a variety of standardized sizes, from AAA to 9V to larger C/D sizes.








Lithium Batteries


Lithium batteries are similar to alkaline batteries, but use lithium instead of zinc as an anode.


Voltage


Lithium batteries can produce voltages up to 3.7V, higher than what alkaline batteries can produce (9V batteries are actually 1.5v in clusters of 6).


Lifespan


Lithium batteries have both a longer operating life and a longer shelf-life than alkaline batteries.


Weight


Lithium batteries weigh approximately 1/3 less than their alkaline counterparts, which, coupled with their longer life, makes them excellent for power-hungry portable devices.


Cost


Lithium batteries can cost up to 2.5 times more than similar alkaline batteries.
