Energizer vs Duracell: 3 Differences to Consider Before Choosing One

After some digging and reading expert opinions, I have found out differences in 3 categories. Let’s check them out.


For sealing and protecting the battery from leakage, both brands use their proprietary technology.

Duralock Power Preserve Technology is in action among Ultra, CopperTop, Rechargeable, Hearing Aid, and Coin Button models.

On the other hand, Energizer cells have PowerSeal technology.

Both of the sealing technologies are very effective. I like PowerSeal more because it can keep the cells safe for up to 2 years inside a device even after completely drained.

We often forget about changing the old batteries and this feature can be a lifesaver.


Both are great at offering longer service life compared to other competitor brands in the market.

However, their NiMH rechargeable batteries have slight differences. Energizer cells rate at 2200 mAh where Duracell rates at 2000 mAh.

Now, those are not official data. So, don’t trust them blindly. With constant consumption by low-current devices, you can expect longer backup from Energizer.

According to some other testers, Energizer Max shows 8% more capacity than Duracell Ultra.


After a side-by-side comparison, you will notice that Energizer batteries are slightly more expensive than Duracell.

Now, I have seen some customers complaining about battery leakage issues with Duracell. Both brands have the same accusation but Energizer has less.

Keeping the longevity aside, it would be wiser to put the bet on Energizer and help keep the devices safe for long time operations.

Which Brand Is Better: Energizer or Duracell?

I think that the winner is clear in this Energizer vs Duracell battle. From independent testers, Energizer shows almost three times longer backup than Duracell.

Indeed, it costs a bit higher. But the investment is worth every penny for the performance, durability, and reliability.

However, there are some exceptional cases where Duracell beats Energizer.

What the test results mean is that both are top-quality products with good shelf life and performance.

In flashlights, Duracell outperforms Energizer. But the opposite is true when you are testing them in a clock.

When it comes to brand awareness and trust, Duracell wins that battle.
