What are the Differences Between Lithium and Alkaline Batteries?
- by Bryan Veldboom - updated on 8/15/2022
As a consumer, you rely on batteries to power a variety of everyday devices ranging from thermostats to activity trackers, wireless game controllers and more. Finding the best replacement battery for each of these applications can sometimes get a bit confusing, especially when you factor in the many different types of batteries available. Today we'll take a closer look at two of the most commonly used disposable batteries, alkaline and lithium. We'll break down their differences in performance and cost and discuss which applications each type of battery is best suited to.
Lithium and Alkaline Batteries Pros and Cons
Here is a basic breakdown of how an alkaline battery compares to a lithium option in performance and cost.
Alkaline Batteries:
- Lower upfront cost than lithium batteries
- Perform best in temperatures of 30℉ to 70℉
- Can hold power for up to 10 years in storage
Lithium Batteries:
- Higher upfront cost than alkaline batteries
- Can last up to 6X longer than an alkaline battery
- Performs even in extreme temperatures ranging from -40℉ to 140℉
- Can hold power for up to 20 years in storage
- Weighs approximately 33% less than an alkaline battery
Which is Better Lithium or Alkaline Batteries?
While lithium and alkaline batteries differ significantly in terms of performance, each has their own unique strengths and weaknesses. As noted above, lithium batteries hold the edge in performance and shelf life, however, they do cost more. The upfront cost of a lithium battery can be up to three times more than an equivalent alkaline battery, making alkaline far more affordable.
One important thing to keep in mind though is that lithium batteries don't need to be replaced as often as alkaline types. Because of this, a lithium battery will offer a better return on investment, saving you money in the long run.
Should I Use Lithium or Alkaline Batteries?
Despite the fact that lithium batteries outperform alkaline types, they are not necessarily the best choice for every application. Due to their superior chemistry, lithium batteries are your best choice for high drain devices which go through power at a rapid rate. Alkaline batteries are a better choice for low and moderate drain devices. Here is a brief breakdown of some of the uses each battery is best suited to.
Devices that are better suited to lithium:
- Wireless video game controllers
- Trail cameras
- Connected programmable thermostats
- Keyless door locks
- Home security systems
- Digital cameras
- GPS devices, activity/fitness trackers & other wearable technology
Devices that are better suited to alkaline:
- Toys
- Clocks
- Portable lights
- Thermometers
- Remotes
- Smoke detectors & fire alarms
Devices that can use lithium or alkaline:
- Flashlights
- Microphones
- Two-way radios
- Baby monitors
- Touchless applications - hand sanitizers/air fresheners, sinks, toilets & paper towel dispensers
