Differences Between Duracell Optimum Vs Energizer Lithium

When it comes to AA batteries, Duracell and Energizer are two of the most common batteries that come to our minds. Which one of them is better? It depends on a few factors.

Duracell Optimum is one of the most popular AA batteries for its power and lifespan. They are the most picked batteries for those remote control cars. On the other hand, Energizer Lithium is claimed to be the longest-lasting battery by their brand. Be it a high-power LED lighting system.

It may seem like both have a different use. Both specialize in different systems. In this article, I am going to discuss these batteries, their differences, materials, and how long they last. Hopefully, by the end, you will be able to pick the one for your best use.

What Is Duracell Optimum Battery?

Duracell Optimum batteries are alkaline batteries with a nominal voltage value of 1.5V. This is similar to any other Duracell battery. But the Optimum line comes with an extra additive, placed on its cathode.

Benefits of Duracell Optimum?

Duracell Optimum AA batteries perform better than comparable alkaline batteries, although they cost more. These batteries have great customer reviews. They are popular among people for their performance, build quality and durability. Another thing to note is their storage and operating temperatures. Which are 41°F to 86°F and −4°F to 130°F respectively.

Advantages of Duracell Optimum:

  1. Better than average alkaline AA battery life
  2. Doesn’t leak
  3. The resealable case may help you lose less of them in the back of the junk drawer

Disadvantages of Duracell Optimum:

  1. Almost as good as a normal alkaline, but much more costly.

What Is Energizer Lithium Battery?

Energizer Lithium batteries are lithium batteries with a voltage value of 9V. These AA batteries are perfect for capturing pictures as they are for gaming systems and lighting systems.

Benefits of Energizer Lithium?

A different sort of AA battery is the Energizer Ultimate Lithium. Alkaline batteries make up the majority of AA batteries on the market. Alkalines have been around for a long time, and most of them are very similar. This Energizer, on the other hand, uses completely different chemistry: it provides greater power for a longer period of time and at a higher voltage. Their operating temperatures are from -40 to 140°F.

The Energizer stays over 1.3V for the entirety of the discharge, however, the Duracell CopperTop drops below 1.3V less than a quarter of the way through. Aside from the significant capacity difference, the higher voltage can also improve the performance of your gadgets.

Advantages of Energizer Lithium:

  1. Doesn’t leak
  2. Energy capacity is constant
  3. Provides similar performance in extreme weather
  4. Works better than any other batteries in high current

Disadvantages of Energizer Lithium:

  1. They’re expensive

Key Factors To Consider Before Choosing Between Duracell Optimum and Energizer Lithium

There are a few key factors to consider before buying any of these such as cost, maintenance, safety, space, availability, etc.

Consider these factors before buying:

Cost

Energizer Lithium costs significantly more than Duracell Optimum. They last longer and provide excellent performance in the high current but this huge price difference is something to consider before you decide which one to buy.

Maintenance

None of these batteries require high maintenance. You can store them in the package they come in. Duracell Optimum comes in a resealable package and it is easier to store the batteries. The Energizer Lithium has regular packaging like any other AA battery.

Safety

Standard Safety measure applies for both these batteries. Keep away from direct sunlight and children. Store in a safe and dry place.

Space

These are AA batteries means they don’t require a lot of space. You can keep them in your drawer.

Availability

Both these batteries are available across the United States. They can be found in Amazon and any local hardware store. Prices may vary depending on your location.

Safety

Lithium batteries must be disposed of differently from alkaline batteries, which may be thrown away with ordinary trash. Using rechargeable batteries wherever feasible is an environmentally beneficial and “green” way of life.

Both firms claim to be in favor of battery recycling schemes. Call2Recycle, a free battery, and smartphone recycling service, is supported by Duracell. According to anecdotal information, both brands have some leakage and safety difficulties.

According to a YouTube video, Energizer batteries leak acid even if they are unopened after they expire, but Duracell batteries do not.

frequently Asked questions (FAQs):

Can I Mix Old And New Batteries?

It’s preferred not to mix the old and new batteries. It is likely to reduce the overall performance.

Does It Matter What Type Of Battery I Use In My Device?

Yes. For example, Zinc carbon batteries do not perform superiorly.

Should I Remove The Device Battery When The Device Not In Use?

If it is going to remain unused for several months, then yes!

Are Lithium Batteries Safe?

Yes.

Are lithium Batteries Considered Hazardous Waste?

No.

Summary

In terms of performance, the Energizer Lithium beats Duracell Optimum but it costs more. On the other hand, the Duracell Optimum provides slightly better performance than any conventional alkaline battery.

If you can spend a few bucks more, go for the Energizer Lithium. About Duracell Optimum, this is a great battery, if you want that slightly better performance, go for it, if not, any regular AA alkaline battery will serve you well.
