By the end of this Energizer vs Duracell showdown, you’ll have the knowledge to pick your perfect battery match. Let’s start by understanding the backstory of each brand.
A Look Back – Origins of Energizer and Duracell
Energizer batteries traces its lineage all the way back to the very beginning of commercially available dry cell batteries. In 1896, the National Carbon Company introduced the Columbia battery, the first mass-produced dry cell battery in the United States. Shortly after, in 1898, the company changed its name to Eveready Battery Company to market the new batteries.
For nearly a century, Eveready and its iconic ‘Cat’s Eyes’ logo supplied batteries to power flashlights, motors, telegraph and telephone systems and more. After being acquired by consumer goods giant Ralston Purina in the 1980s, Eveready batteries were rebranded to ‘Energizer’ in 1986.
Today, Energizer Holdings Inc. offers batteries and lighting products worldwide, marketing various battery technologies including alkaline, lithium, rechargeable and more.
Duracell’s history is comparatively shorter but no less impactful. Tracing its origins to 1920s, the company is connected to P.R Mallory and Company, an early battery manufacturer that supplied batteries during World War II.
But Duracell’s defining moment came in 1964 when it launched the first AAA sized alkaline battery to power the newly introduced Kodak Instamatic camera with an integrated flash. This pioneering format remains the go-to standard for AAA batteries to this day. Since then, Duracell has continued to innovate, most notably with the iconic Duracell Bunny advertising campaign.
Currently owned by Berkshire Hathaway, Duracell also offers primary alkaline, specialty lithium cells, rechargeables and more across global markets.
Now that we know a bit about the background of each player, let’s take a closer look at what goes inside their batteries.
Battle of Battery Tech – Inside an Energizer and Duracell
When it comes to batteries, performance and reliability ultimately depends on technology. From form factor to chemistry, let‘s examine some key tech specs of Energizer and Duracell batteries.
Chemistry
For their primary battery ranges, both brands use similar alkaline and manganese dioxide chemistry. This reaction between zinc, potassium/sodium hydroxide electrolyte and a manganese dioxide catalyst produces voltage efficiently to power devices.
On the rechargeable front, Nickel-metal hydride (NiMH) tech is utilized for reversible charging. Here, nickel oxide hydroxide and a hydrogen absorbing alloy react to enable repeated recharging.
For specialty lithium cells and other applications, precipitates, carbon compounds and additional catalysts are used.
Materials
Common negative terminals are made of zinc alloys while the positive cans feature steel. Internal parts use similar graphite, ammonium chloride, zinc and brass components.
Seals play a crucial role in preventing leaks. Energizer’s patented Power Seal and Duracell’s Duralock tech allow the batteries to be air and water tight during transportation, storage and use.
Environmental regulations have also reduced heavy metals to miniscule levels in both brands.
Voltage & Capacity
The nominal voltage is 1.5V for AA and AAA cells, with slight variances per battery type. Capacity or mAh (milliamp hour) rating, which signifies runtime, goes up to 3000 mAh for certain alkaline cells. For rechargeables, 2500 mAh batteries are common.
Additional Features
Special features also impact battery life. For example, Duracell’s PowerCheck indicates remaining charge, while Energizer’s MAX Tech maximizes runtime in high drain devices.
So when it comes to underlying battery technology, both reputed makers adopt similar chemistries and construction standards to deliver reliable power. Duracell does have a wider range of specialty cells on offer. Next, let’s compare how these translate to real-world performance.
The Acid Test: Comparing Battery Performance
Now that we know what goes inside an Energizer and Duracell battery, how do they stack up when powering everyday devices? To arrive at a verdict, we will analyze key performance criteria:
Lifespan
Thanks to similar alkaline chemistry and quality manufacturing, both battery brands deliver approx 10 years of shelf storage life. For usage lifespan, while Duracell batteries are rated to last up to 2 years (actual runtime varies by device), Energizer MAX can last 23% longer, even in high drain electronics.
Rechargeability
In the rechargeable segment, Duracell batteries manage up to 500 recharge cycles i.e. lasts for 2-3 years with weekly recharging. Energizer rechargeables officially state 1+ years but users report getting 3-5 years of runtime with 1500 charges.
Extreme temperatures
Energizer Ultimate Lithium batteries function between -40°F to 140°F owing to pure lithium innovation. Duracell also lists broad operating temperatures thanks to proprietary Duralock protection. Against extreme heat and cold, both brands deliver ample runtimes.
Leaks
Leakage is a key cause of battery and device damage. However, extensive testing shows seal integrity persists across both brands, with under 5-7% cells showing minor leaks even under rigorous temperature swings.
So whether its lengthy shelf life of primary cells or durability of rechargeables, Energizer and Duracell are evenly matched when it comes power metrics. But what about the all important factor for consumers – pricing?
Battle of Budgets: Energizer vs Duracell Prices
Pricing plays a key role in battery purchases. Let‘s see how much you can expect to pay:
MRP Comparison
| Battery type | Pack quantity | Energizer price | Duracell price |
|---|---|---|---|
| AA Alkaline | 4 pack | $3.97 | $4.99 |
| AAA Alkaline | 8 pack | $5.49 | $6.49 |
| C Alkaline | 2 pack | $4.49 | $5.49 |
| 9V Alkaline | 1 pc | $5.97 | $6.49 |
Across popular battery formats, Energizer packs are generally 15-20% cheaper than equivalent Duracells. Factoring in frequent multi-pack discounts and sales, the cost difference can be even higher.
Rechargeable Value
A 4 pack of Energizer AA 2500 mAh NiMH batteries along with charger costs $18.99. A similar Duracell kit with 4 PCs of 2000 mAh cells and charger comes for $22.49. Across various bundles, Energizer rechargeable starter sets are approx 15% more economical than Duracell.
Bulk Savings
Buying larger bulk packs allows even greater savings, especially with Energizer batteries. Cost per battery comes down to ~$1 per AA battery on a 48 pack vs ~$2 per AA in 16 pack for Duracell.
So if you are looking for affordability, Energizer provides better value across the board. But how do the brands compare when it comes to eco consciousness?
Going Green – Energizer vs Duracell Sustainability
With growing environmental awareness, power sources are expected to evolve towards energy efficiency and responsible recycling platforms. Let‘s analyze some sustainability parameters:
Materials
Both companies have phased out the use of added mercury and cadmium in batteries for reduced soil contamination upon disposal. Energizer also reports 35% recycled steel and 5% recycled zinc in battery casings.
Recyclability
To prevent batteries ending up in landfills, Energizer and Duracell partner with Battery Recycling Corporation and Call2Recycle programs respectively. These offer extensive battery collection points across North America.
Carbon footprint
AA alkaline batteries have 5+ year shelf lives, allowing efficient warehousing and transport compared to perishable goods. Combined with renewable packaging, water-based ink printing on packs, both brands are driving towards a minimal carbon footprint.
Promoting responsibility
Through public awareness campaigns about proper battery disposal and silence poll localisation to detect leakage, both corporations are promoting responsible consumer behaviour for a cleaner planet.
When it comes to eco-impact mitigation, Energizer and Duracell are on the same page – investing in conscientious material sourcing, production practices and consumer engagement around sustainability.
