Of course Duracell won, look at the size of that AA battery

Screw alkalines, use NiMH. One YouTuber recently found that Ikea's NiMH for $6.99 are almost certainly rebadged Eneloop Pro which are $15-20

IKEAs batteries are great. :)

i would like a more consistent test with different current ie a constant current at 100ma 250ma 500ma and 1A and a specified cutoff voltage

8 years ago | Likes 4 Dislikes 0

Well duh, obviously the longer batteries are gonna have more juice in them. It just makes it harder to fit them in stuff.

Are there special batteries that won't leak after several years?

Most have a 10 year shelf life. Lithium will hold a charge and wont leak for an extremely long time.

Tests by me as a 10 year old kid with a Gameboy say you're wrong.. Duracells lasted sooo many hours longer than Energizer and Eveready.

Duracell would last the entire day playing. Eveready would die within 3 hours.

Generic OEM batteries like Bexel will not fucking die and it's amazing.

8 years ago | Likes 5 Dislikes 1

And I remember tests showing that there is barely any difference between the big name brands and cheap generic ones.

8 years ago | Likes 40 Dislikes 2

All of the store brands are made by either Duracell, Energizer, or Rayovac - they sell their factory seconds to other labels.

8 years ago | Likes 1 Dislikes 0

WHAT! You mean it’s neither of the extremes and likely some grey area in the middle? Ludicrous!

8 years ago | Likes 14 Dislikes 0

Anecdotal, but personal experience says otherwise. If a cheap brand lasts 2 weeks in my mouse, that's a long time for them. Big name brands

8 years ago | Likes 3 Dislikes 1

last at least 6 weeks.

8 years ago | Likes 4 Dislikes 0

True, but usage counts. Kirkland's don't last as well in electronics as you'd think; I'm thinking it is because they produce a lower voltage

8 years ago | Likes 62 Dislikes 6

If true it's not because of lower voltage. Voltage is a factor of the chemistry and can't be changed.

according to my high school science project, in high drain devices, that graph becomes pretty flat across all of them

Also, Depending on what store you're at, the best bet is the cheap ones because of high turnover.

In what non-electronic object would one use a battery?

As in the chart, a flashlight. They don't specify there, but an incandescent bulb will glow until there isn't enough current to warm it up.

There are only 3 main battery manufacturers - Duracell, Energizer, and Rayovac. Factory seconds are relabled and sold as store brands.

8 years ago | Likes 1 Dislikes 0

You can see that in the chart - first 3 are made by Duracell, the next set by Energizer, the last 2 by Rayovac.

Only one of each tested, and each in a different "identical" flashlight. Should test uniformity with the same battery in each flashlight.

Not only that but just because it's the same model flashlight doesn't mean the bulbs/LEDs have exactly the same power consumption.
