In this video I take a look at energy storage and density in batteries (cells), supercapacitors, etc. I also look at the characteristic discharge curve of these devices and how that can be important. I do a comparison of the new Duracell Quantum AA battery (cell) vs the Energizer Ultimate Lithium Battery..which one is "the world's longest lasting battery?"

* What is energy density: Wh/kg - watt hour per kilogram
The spreadsheet with energy density data:

Great Video, Its nice to know what batteries to buy. Are you going to test the Energizer® Ultimate Lithium AA vs Energizer® Advanced Lithium AA ?
-
Very interesting video.
Li-ion and Li-Po Batteries are common these days, what are the characteristics and energy density of these types of batteries? what are the difference between Li-ion and Li-Po Batteries?
Regards,
Yasser :)

Any chance of testing GP batteries? Those are really common in Europe, and I've always wondered if the price matches the package. Website is http://www.gpbatteries.com/ (http://www.gpbatteries.com/)

Have a look at http://www.batteryshowdown.com/ where lots of European batteries are tested at 200mA and 1A. I've personally sent a batch of batteries to the guy doing the tests.

Martin, before you dump the alkalines in the bin, I think it would be interesting if you can do a comparative teardown and have a look at whether there is any visible difference with their inner construction that sets the Duracell Quantum apart.
-
How about talking a bit about money? Even though prices can vary because of stores, discounts, quantity, shipping fee, etc., it would be nice in my humble opinion to include a column in the spreadsheet. Just for the sake of "what if". The reason is simple: it's great that the Energizer Ultimate Lithium (EUL) has the best Wh/kg ratio, but it's also more expensive than the Duracell Quantum (DQ).
I did a quick check on Amazon and found that at the moment a 12-pack EUL costs 19.72 USD (1.64/pc) while DQ 10.97 USD (0.91/pc).

I did a quick compare of what is at my local Makro. Energiser is about 40% more than the same cell branded Ever Ready - same construction, same printed batch numbers but different stick on sleeves. Duracell is about twice the price. Preices per cell vary a lot, depending if you buy 2, 4, 4+2, 6, 6+2, 8 16 or 20. Funny enough the 16 pack was the cheapest per cell, about half the price of the 4 cell pack, though that was probably because they were on special. The Panasonic cells I only tried once, they did not even last 3 months in a wall clock.

Yup...I plan to do a whole host of cells so I plan to include GP as well.

Yes...nice site...I remember coming across this some time ago.

Good idea and noted...will see if I can fit this in a future video.

Noted...meant to mention that it would be easy to add price per Wh/kg...I'll add this at some point in time.

Good point Sean...this is something that crossed my mind when considering how to obtain a "fair" price point per cell...

Can you test and report what the internal current drain is on different batteries. How long will they hold a charge, ie for long term data recorders that use little current in long sleep modes.

Just ordered the Energizer® Advanced Lithium AA...so will add that to the testing as well.
Cheers,

I love the testing and technical data you've gathered for this new battery. I find the energy density analysis concept very interesting but not as practical for me as cost per hr in my kids high tech toy. I noticed someone else suggested adding price to the spread sheet. My price is something I can add on my own (since the file is available) but I'm missing some testing data for the more basic batteries: Energizer Max (standard), Energizer Lithium Ultra (tier 2), and a cheep competitor Rayovac alkaline. The spread sheet could then have a price per battery (modifiable for anyone to use their own prices) and a separate column for calculated cost per kW/hr both in high and low usage categories.

I'm also curious, What batteries you're using in your personal volt meters, cameras, etc after doing this testing? A real-life application of the data/testing in a separate video might get you increased traffic.

Thanks for your post.
I've had a kind offer to make my data more friendly to post on the web and your suggestions of the addition categories make a lot of sense.
I use the Energizer Lithium's in items that are high energy consumers and starting to use the Duracell Quantum in my other equipment.
There will be several videos related to my application of battery technologies based on my testing.
Cheers,
Martin.

sorry for reviving an old thread
has there been anyone who tried to do the same series of power/life tests on 18650/26650 types of cells?
-
18650/26650 cells are on my list to test soon....will post results once done.
