Energizer Lithium AA Battery Review

[@glasstronic]

Those Li cells have an integral "polyfuse". It is a temperature dependent resistor (just under the (+) terminal). Without that, a short circuit across one WILL cause a catastrophic failure (fire, possible explosion). That's why the seemingly odd behavior when they get warm from use. Yep, I love those Ultimates! Thanks for posting. :-D

[@dcarrera01]

Thanks for the explanation. That's very interesting. Do alkaline batteries not need a similar safety device?

[@MarcoFranceschini1971]

A PTC positive temperature coefficient device...to limit the current and avoid thermal runaway.

[@tl1024]

This review was excellent, when I took my new Energizer ultimate max lithiums out of the pack, they were so light, I thought "these are fakes". So glad to see this! Thanks for the awesome test.

[@NickStubbs]

Your welcome T L and thanks for the feedback. I felt the same about the weight...incredible ✌️

[@thetriggerhappypwner]

I use these batteries for all sorts... remote controls and clocks (with digital weather info included) to name a couple that I use them for. I have a pair of these, that expire at the end of this year, installed in a digital radio controlled clock that I installed in May 2015, and they are still going strong!

[@NickStubbs]

Wow...nearly 7 years! Phenomenal 👍

[@TheStevenWhiting]

7 years old! And I've only discovered Engerizer Lithium. Took them out of my multi-meter not realising they were lithium! They've died so put tape over the contacts so I had drop them in the recycling at work.

[@douglasheld]

This is fascinating. I've been reading the Energizer Ultimate Lithium data sheet. The batteries will provide such a high load that they contain an internal overheat protection (as previously commented 3 years ago by glasstronic). They function best in a 10% duty cycle (for instance, 1A for 10 seconds, and then 90 seconds to cool off).

[@NickStubbs]

Interesting and thanks for the feedback 👍

[@frankenfoamy]

Those batteries have qwirk in that they unload test at 1.77volts. When my trail cam will no longer take photos they are at 1.57 volts. Keep this in mind when testing batteries to use later. Otherwise best batteries I have used.

[@dcarrera01]

But this is the nature of the Lithium - Iron sulfide chemistry of the batteries. Their open circuit voltage is around 1.8 V but under load it drops to around 1.5 V which is exactly what you need for them to be a drop-in replacement for traditional AA batteries. They would not even be able to legally sell them as AA if the batteries did not run at around 1.5 V.

[@garyolson3315]

Thanks for the great video! I have a number of telescope mounts that I forget to replace batteries, and they leak. I will be installing the Energizer Lithium now.

[@krish2nasa]

Nice review! The quickly repeating high discharge currents cause the internal battery heating to raise that inturn will kickoff the PTC. So this is the expected behavior of the PTC safety feature. Thanks

[@bridgendesar]

Did a test with Energizer lithium in a mouse once, got 134 days, tested one of those rechargeable AA's with a USB plug on the end, got...............20 days. Got a more efficient mouse now ( Logitech t400 touch), el cheapo batteries last months, but haven't kept track!

[@92000]

USB rechargables are Chinese fake cells. Just for you to know. Try rechargeable Duracell Turbo 2500mAh or try some good Alkaline Batteries. (I'm 1,5 years on my mouse with some type of Alkaline Energizer rn [record]) Lithium are still too expensive for their advantages over Alkalines in my opinions.

[@RonPrieston]

I've mainly used the Eneloop rechargeables, but am slowing changing over the Powerex as I find them better.

[@peterkwakman7440]

I bought a LLOYTRON alkaline charger from Amazon,so long as the cells are 1.2v minimum they can be recharged,(important to read instructions).I had loads of success bringing the cells back to life.The old story of been unable to recharge them is probably that it is not economical to do so,but hey if you get a couple more uses out of them,then it's worth it,important to have a voltmeter

[@Halabalooza]

I've tested energizer ultimate lithium aaa batteries in my petzl tikkina headlamp (150lm). They worked THE SAME TIME as simple alkaline Duracell.

[@1ohtaf1]

Normal alkaline batteries build up their internal resistance as they deplete, so they are putting out less power as they get used, which could be the reason why you see similar run times with both.

[@OleJacobsen]

The difference is weight is due to the different materials/chemicals used. A Duracell alkaline is 22 g and the Energizer Lithium is 14 g. The downside (apart from price) is that lithium batteries have a dramatic "end life" curve whereas alkaline batteries decay more slowly and partially recover. Bu the main reason I use Lithium batteries is that they NEVER leak.

[@mindsharping]

I use a single a4 Zinc Carbon battery in my clock and replace it about every 14 months. Three years ago I replaced it with an Energizer Ultimate Lithium battery expecting it to last for the rest of my life. strangely it was flat after only 15 months. I was so surprised I actually kept the cell. (It is still flat.)

[@darkgroov]

The lithium one they should be used for power hungry devices as the discharge quick enough if not used ( correct me if I'm wrong ) and to be recharged with reacharger that supports lithium not NiMH

[@NickStubbs]

You may be right. These are not rechargeable though. I was conducting the test with shooting weddings in mind, that may require a lot of continuous flash use. For that they would work well but to leave in a low usage device may not be so good 👍

[@jimbobxcityguy5338]

I believe they are so light (engergizer ultimate) is they are li polymer vs ion in others.

[@GlobalGaming101]

You should test chargeable lithium-ion AA batteries. They have usb A ports to recharge.

Hello, I would like to ask you for a link. I have searched for AA rechargeable Lithium batteries, but I couldn' find anything. Best regards

[@bajaminibike711]

I went to the lithium AA in my trail cameras a couple of years back. I believe they do last longer than any other battery I've tried. I did discover a strange failure just yesterday. My trail cameras use 8 batteries in series for a 12 vdc supply to the contact points in the battery drawer of my cameras. I found my camera inoperative, dead. I used a FLUKE 87 multimeter to measure voltage of each battery. I have some that have been completely drained and some were still in the 1.5 + vdc range and I have one I'd like someone to explain. The battery has reversed polarity and measures 2.5+ vdc??? E.C.Smith USA

[@bajaminibike711]

And another thought, anyone found China making knockoffs of these? Might explain this failure.

[@Quettesh]

Lithium batteries are great for gaming mice using them to keep the weight down as much as possible while giving it much longer life.

[@NickStubbs]

Good point!

[@tarstarkusz]

The recharge time seems high. The thing about primary lithium cells is their ability to output current. The internal resistance is so low that the physical temperature is the only real thing providing a limit. That is why they are fused. If an alkaline takes 5 seconds to recharge the caps in the flash, the lithium cells should be as fast as NiCad. For low resistance, nothing beats NiCads. You get less life, but there is no other option for power delivery with AAA, AA, C, D and 9V. You have to go to lithium-ion to get even close, but lithium ion are 3.7v

NIMH cells are the only way to go. You can get them from Ikea for about the same cost per cell, but they last for years and years. I have a Turbo Xpress (a portable TG-16) and a Sega Nomad (like the Game Gear, but plays Genesis games).

[@Mercury1955]

The chemistry of a single Lithium cell is 3.6 volts so I'm not sure what they do to bring it down in the AA package. Some kind of voltage divider or resistor?

[@dcarrera01]

No. Batteries that say "Lithium" are not all the same. The Lithium batteries in the AA format have a different chemistry from the "cells" you're thinking of. They both have Lithium in the anode, but the cathode is different. The Lithium batteries that look like a button usually have MgO2 on the cathode and a nominal voltage of 3V (open circuit voltage = 3.3V) but for the AA format they use FeS2 on the cathode which does have a nominal voltage of 1.5 V (open circuit voltage = 1.8 V).

Energizer ultimate lithium is rechargable?

[@prymus141]

No. They are a single use AA batteries.

[@tarstarkusz]

You absolutely should not use alkalines that were initially depleted in such a high drain device. When you put these in something like a mouse after abusing them with that flash, they are very prone to leaking. You should not be using primary cells as anything but emergency backup. There is no scenario where anything but NIMH cells make sense with such a device.

[@NickStubbs]

Oh and they mean 80% longer than their rival. I.e. If Duracell's last 60 minutes, the Energizer will last: 10% extra = 6 minutes longer 80% extra = 48 minutes longer Duracell's last 60 minutes Energizer's last 108 minutes...80% longer.

Duracell's are way overrated, Energisers have nearly a 20 yrs shelf life from new whereas Duracell only 3 to 5 if ya lucky, do the maths.

What do you think about this coment on these batteries, from a KZbinr : "The Energizer ULTIMATE LITHIUM battery is a very dangerous battery and should not have been produced in the first place. This battery has no smart voltage sensing circuit built into the battery that would otherwise allow it to be recharged unattended. This battery can be safely recharged up to a certain voltage, but you must not leave the battery unattended should you decide to recharge it to its original charge. In a nutshell, Energizer should have known better than to produce a battery like this with no smart voltage sensing circuit built into the battery itself. This is very irresponsible of Energizer as this battery is a time bomb waiting to explode. A lithium battery like this is much more dangerous than other lithium cells that do contain voltage sensing circuits which tell battery chargers when to cease charging unlike the Energizer ULTIMATE LITHIUM battery, which does not. There is a warning is extremely FINE PRINT that tells the user that this battery can explode even if it is installed backwards. Energizer is extremely irresponsible in this regard. Batteries are quite often inserted backwards by accident all over the world. I've done it, and everyone else has done this too. How many homes and other property are going to have to burn up as a result of such irresponsibility?"

[@qtadosol]

If confirmed, I think it's a pity if this really is hapening, let's hope for the best, and theat they (Energizer) do the proper adjustments in the future to avoid any of these problems...

[@joshuaewalker]

@PS4 Custom Gamer Not to be antagonistic, but you're wrong. I've personally tested this myself. If you drain both a regular alkaline battery and an Energizer Ultimate Lithium at the same rate, say 500mA, the lithium battery has significantly more power. And, then, if you do the same drain test at a much lower rate, say 100mA, the power difference is even greater. Energizer Ultimate Lithium batteries are _the_ most powerful alkaline-style batteries you can have for any device whether high-drain or low-drain.
