Not all Energizer AA alkaline batteries are manufactured in the same region, and the quality might vary depending on the production site. The location of origin may be determined on the battery's positive side. All Energizer brand batteries have two positive posts, one near each end, so they can be distinguished easily by sight alone.
The term "alkaline" refers to a class of chemical batteries that use an alkali metal as the active material in the negative electrode. Alkaline batteries are commonly used as replacements for acid-based batteries because they are less toxic and produce less hazardous waste.
Alkaline batteries come in many different sizes and shapes. They usually contain six volts or seven volts of electricity. Alkaline batteries are available for most applications where you would find acid-based batteries. There are even alkaline batteries designed specifically for use with electric vehicles.
Alkaline batteries should not be placed in the disposal unit with other toxic substances; instead, they should be taken to a recycling facility. Recycling reduces landfill space and energy consumption while providing useful materials for new products.
The chemistry and construction of Energizer (r) Ultimate Lithium (tm) batteries differ from those of alkaline batteries. Energizer (r) alkaline batteries are offered in a number of sizes to suit a wide range of uses. Ideally suited for regularly used gadgets. AA and AAA cards are pre-charged. When fully discharged, these batteries can be recycled or reused.
Energizer (r) Ultimate Lithium (tm) batteries are smaller but longer-lasting than alkaline batteries. They are also maintenance free. There is no need to change the battery in your flashlight or other portable electronic device that uses an Energizer (r) Ultimate Lithium (tm) battery.
These batteries are ideal for use in devices where size matters, such as cell phones, PDAs, and power tools. They offer greater capacity than alkalines and last longer too. You won't need to replace them as often.
Furthermore, they are environmentally friendly because they don't contain any toxic substances like mercury in their composition. What's more, they are recyclable which means you shouldn't throw them out after use.
So next time you're looking for a replacement battery, consider using one of these instead of an alkaline battery.
The advantage of lithium batteries over alkaline batteries is that they live much longer. Because Energizer e2 lithium AA batteries produce 1.5 volts, they may usually be used to replace any ordinary alkaline AA unit. However, due to the nature of these batteries, they do require more care than standard alkalines.
Lithium batteries can also handle higher current demands than alkalines. This means you can use them in devices that need more power, such as lights, heaters, and motorized equipment. They are also less likely to burn out when exposed to high temperatures or extremes in temperature.
Alkaline batteries on the other hand, while having a longer life span than lithium batteries, cannot handle high current loads and their capacity decreases over time. These batteries should only be replaced if you plan to replace your entire stash at once with new batteries.
It's important to note that although lithium batteries can handle more power, this doesn't mean they're appropriate for every application. They are not designed for low-current applications such as flashlights, radio transmitters, or small motors. If you have an application that requires high currents but not so much power that would cause lithium batteries to degrade excessively, then these are the batteries for you. Otherwise, consider using alkalines or another type of battery.
