Energy Storage and Density - Duracell Quantum AA cell vs the Energizer Ultimate

[MJLorton]

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?

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/

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.
