Energizer vs. Duracell: What’s the Difference?
Energizer and Duracell manufacture great batteries made of high-quality materials and durability. We pit them against each other to help you choose the best. Let’s check them out.
History
Historically, Energizer has been around for over three decades longer than Duracell. Energizer was established in 1896 under the well-known brand, Eveready Battery Company. Eveready used the name for nearly a century before it changed to Energizer in 1986 after Ralston Purina purchased it. Since then, the company has produced Energizer batteries and Varda, Eveready, and Ray-O-Vac.
On the other hand, Duracell is linked to P.R. Mallory Company, a battery manufacturing company. They first produced batteries for military equipment, then eventually began making them for other products.
Kodak created the first camera with a flash in the 1950s. This new design needed a different battery size, so pre-Duracell manufactured an AAA battery. But, it wasn’t until 1964 that Duracell was introduced as a brand name.
Energizer and Duracell Products
Both brands offer more popular types (9V, C, D, AA, and AAA) and provide lesser-used sizes like the J, AAAA, and other button-sized batteries.
They also offer rechargeable batteries with the same chemistry, which includes Nickel-metal hydride, zinc-air, silver-oxide, and lithium. We decided to use the more popular sizes, the C and AA batteries, as a point of comparison.
C batteries are the popular size that’s used for gadgets like radios, remote controls, cameras, and some motorized toys. Duracell’s C batteries specifications include DuraLock Technology and are suitable for devices with high drains like digital cameras, shavers, flashlights, and high-powered remotes or toys.
Duracell provides more C battery choices because it has the Duracell Ultra C LR14, ID1400, Industrial Duracell (Procell) C LR14, and Duracell Plus, C LR 14. It also manufactures the rechargeable C 3,000 mAh, which can stay for nearly a year when not in use, can be charged about 400 times, and lasts up to six years in storage.
Energizer C batteries, on the other hand, fall under the Max name. These batteries are manufactured using long-lasting alkaline chemistry that gives them a 10-year lifespan and holds power for the same period. Energizer also has its version of rechargeable C batteries: the Recharge C NiMH. This rechargeable battery can be charged about 1,500 times and has less power at 1,500 mAh.
AA batteries are a trendy size as well. They’re used for products like remote controls, clocks, and even smaller battery-powered flashlights and toys. The Duracell is rated at 2,000 mAh, while the Energizer AA is rated at 2,300 mAh. The value of mAh determines which device will provide power for longer. Therefore, the AA of the Energizer will serve longer. It is also heavier and bigger than the Duracell version.

- LED Charge Status Indicator shows when charging is complete and Auto Shutoff when batteries are charged
- This battery charger works with all rechargeable AA and AAA NiMH batteries
- The Duracell Ion Speed 4000 Battery Charger charges 2 or 4 batteries at a time
Market
Duracell owns a larger market segment compared to Energizer. It commands about 29%, while energizer has 25% of the market. Energizer has been around longer than Duracell, but the latter has become even more popular.
Prices
Energizer has a price advantage over Duracell. Both brands often provide bulk buying with discounts and offers, but Duracell is always on the more expensive side of the price range.

Eco-Friendliness
Eco-friendliness is extremely important — in general and to consumers. Tests on battery leakage on both battery brands at different temperatures have shown that both displayed minimal leakages.
Usually, rechargeable batteries are friendlier to the environment because they can be used multiple times, so the worry of recycling or disposal is much less.
Both brands provide detailed information on their websites on either how to dispose of or recycle dead batteries. And they no longer use the deadly mercury in their manufacturing processes. That’s why these brands are much safer for the environment.
Energizer uses the Rechargeable Battery Recycling Corporation, while Duracell supports the Call2Recyle program. So, it seems that both batteries are playing their role in safeguarding the environment as best as battery manufacturers can.
Battery Life
The technology used by both brands for rechargeable batteries is Nickel-metal-hydride. Their mAh ratings are, however, different, as seen in the AA case where Energizer offers 2,200mAh while Energizer offers 2,000mAh. On paper, the higher the value of the mAh, the longer the battery would last.
The two batteries mentioned above showed that the Duracell one lasted longer than its counterpart. When tests were conducted on the same types of clocks, the results indicated that Energizer AA lasted almost three times the Duracell. In torches, the Duracell lasted three hours longer than the Energizer for the type C batteries. Different tests did not provide conclusive results to discern which brand is superior.
