Which brand of Alkaline Battery Lasts the Longest

Dec 10, 2015

You may wonder which brand of alkaline battery lasts the longest in your daily use environment. Today we are going to take a test to find how what. 

Independent Evaluation Data 2013

The evaluation is:

Our Theory

We call the Duracell brand will survive the longest because of their marketing claims that the copper top can not be beaten by any other alkaline battery. AA buy batteries in bulk

Our Stuff

Four of same size, the exact same battery kind as well as brand of torches.

We used two D size batteries from all these producers:

- Rayovac 

- Duracell 

- Energizer 

- Eveready

Our Process:

By using two test batteries we examined all the newest torches. We subsequently tape place the batteries kinds that are distinct in all the torches that are marked and tagged each standard torch together with the battery kind brand name.

We are going to turn on each torch in once, before beginning the evaluation. We left them. We logged the time that the torches turned to the on location. We saw the torches till they record the period of time and went out. When one torch goes out before another, we waited and simply add two more of the exact same battery sorts.

Our Variants:

Distinct brand of batteries is our variant. We restrained the state of every torch.


The Eveready brand battery and the Duracell brand lasted just 6 hours and 35 minutes and 15 hours, respectively. The Energizer brand lasted 15 minutes and 22 hours complete.

As well as the big winner: The Rayovac continued 24 1/2 hours.

The Eveready brand torch light needed to replace the batteries fairly frequently and went out really fast. We additionally found that when the Eveready brand was not going alive it went subdued quite slowly.

Our hypothesis was completely incorrect that Duracell last the longest. We rapidly came to the final result that the information supports the RAYOVAC BRAND more than Energizer and Duracell. This also shows that even believed Duracell prices more, they tend not to survive the longest.

We propose to buy Rayovac over other brand of batteries. We expected this may help you save money as time goes on and helped you out. Our aim in running the evaluation was to supply our clients having the most bang for the dollar also to locate a very good battery for the cash.
