Lithium Batteries

Batteries are among the most common power sources when it comes to the electronic devices that you use on a daily basis. In addition to choosing batteries that are the right size, decisions regarding the power source within your battery can also make a major difference in terms of performance. Here at Walgreens, we have an assortment of lithium batteries that can help keep your electronics powered for extended periods of time.

Lithium vs Alkaline Batteries

When it comes to "primary batteries" (the non-rechargeable variety that you use in most of your consumer electronics), there are basically two distinct types to choose between. Alkaline batteries use zinc and manganese oxide as their power sources and have been the most popular type of standard batteries for decades. Though alkaline batteries are typically inexpensive, they need to be replaced fairly often and are more likely to lead to problems like leakage. Lithium batteries, on the other hand, use lithium metal or compounds for power. After mainly being used in coin and button batteries for years, many manufacturers have introduced lithium batteries in sizes like AA and AAA over the last decade. Though these batteries tend to be a little more expensive, they can also provide some major benefits.

Advantages of Lithium Batteries

One reason why lithium has long been a common anode (power source) used in smaller batteries is the fact that this compound is so long-lasting. A lithium battery used in your watch or other personal device might last for years without needing replacement. This long life can translate to other electronics like clocks, smoke alarms, and digital cameras as well, and it may make lithium the best choice for your crucial electronics. In addition to a longer usage life, lithium batteries have a longer shelf life than their traditional counterparts. They are less likely to leak during standby usage, which might make them a safer choice as well. Lithium batteries shouldn't be confused with lithium-ion batteries even though they share a similar name. While lithium-ion batteries can be recharged, regular lithium batteries cannot, and they may leak or explode if you attempt to charge them.
