    Today, we are going to talk about Alkaline & Lithium batteries.

    Alkaline Batteries

    Sciencing.com stated an alkaline battery is a dry cell battery with a zinc anode (the positively charged end of the battery) and the cathode (the negative end) wrapped in a steel case filled with zinc.

    Alkaline batteries come in a variety of sizes for different purposes including AAA, AA, and C that are used in toys and other electronic devices, and button cell batteries that also come in different sizes and are often used in medical devices like hearing aids.

    Lithium Batteries

    How Stuff Works stated these batteries are often found in electronic devices such as cell phones and laptops because they can be recharged and used several times. They’re made from lithium and carbon and come in the same varieties as alkaline batteries (AAA, AA, C, button cell, etc.).

    What is the difference between those two batteries?

    POWER: lithium batteries last much longer.

    PRICE: alkaline cost substantially less than lithium batteries.

    VOLTAGE: If you decide to replace alkaline with lithium, it is important to check the replacement has both the appropriate voltage and type/size. The lithium AA batteries produce 1.5 volts, so they can be used to replace any regular alkaline AA units in most cases.

    OPERATING TEMPERATURE: Lithium batteries perform even in the most extreme temperatures, making lithium batteries perfect for outdoor devices. Lithium batteries operate in extremely cold climates or extremely hot climates where alkaline batteries cease to function.

    WEIGHT: Lithium batteries are much lighter than alkaline batteries. This is a great convenience for portable devices.

    Alkaline manganese dioxide batteries, commonly known as alkaline batteries, are good all-around batteries for everyday electronic devices and last longer than some other types. However, lithium iron disulfide batteries, or lithium batteries, designed to last longer, making them a good choice for high-tech and smart devices.

    Lithium can operate without failing in a very cold climate, so it's ideal for outdoor applications. Lithium batteries are lighter than alkaline batteries, so they offer an advantage when used with portable devices, especially cordless power tools.

    In short, a lithium battery can be used as a high-performing alternative to a standard alkaline battery. However, the benefits come at a cost: Lithium is a more expensive technology, which means a higher price point. These batteries can even outlast the normal lifespan of some inexpensive, noncritical devices, like toys, so the extra cost may not be justified in every case.

    Thanks! For the most part, I've completely moved away from alkalines in favor of NiMH and Lithium.

    I like that lithium batteries don't leak and destroy devices like alkaline can do.

    Don't try and recharge a lithium battery unless it SAYS it's rechargeable. The 1.5 volt ones aren't. Most lithium batteries you buy in the store aren't.

    Lithium ION batteries are rechargeable. Those are used in portable devices.

    Improper charging can cause a lithium battery to explode (except for lithium iron phosphate)
