TEST AA: BATTERIES Eneloops - Primary Lithium (NICE and ENERGIZER) - Alkaline

+1. Thanks for the review. I've been eyeing the NICE cells since FT listed them and been waiting for someone to review.

You do have a collection of batteries. You even provided a data sheet, too. Nice

I got 2 packs and I just tested 4 batteries, two from each pack.
Fresh out of the box I discharged them at 1A and I got the following
Battery 1: 1770Mah
Battery 2: 1778Mah
Battery 3: 1776Mah
Battery 4: 1762Mah

Then I charged them and tested again fresh out of the charger and I got the following:
Battery 1: 1882Mah
Battery 2: 1885Mah
Battery 3: 1884Mah
Battery 4: 1883Mah

So it’s basically 1900Mah at 1A for all of them, and very little variance. They pretty much perform like the last Eneloops I got. Not sure about how they retain charge in the long term, but the “out of the box” values are really promising imho.

Wow, they sure looks promising & very impressive balance capacities out from a random blister pack.

For the price, its hard to beat but yea, don’t know in long term usage/storage.

Thank you for your time to test them superpila :beer:

*What’s the Charger*for Primary Lithium (1.8V): Energizer Lithium and NICE Lithium?

Nitecore i4 can work or not ?

AFAIK Primary Lithium are not rechargeable.

Nitecore i4 can charge rechargeable Li-ion & Ni-MH batteries.

I added some runtime curve AA flashlights. :slight_smile:

I just got the Klarus P1A. Will it make a difference if I use the Energizer Ultimate Lithium as opposed to the Energizer Advanced Lithium which you used in your test? The Klarus is going to be used in an emergency kit. Thanks.

Sorry beahaven , there are a mistake in one of the graphic, I said Energizer adv. Lithium, but as you can see in the first pic of this review, the energizer that I’ve used for test was Energizer Ultimate lithium.

Here (I use Energizer Ultimate lithium and not Advanced lithium)

Thanks for putting that old thread back up, it is a very interesting test!
From what I can see, the eneloop will last half as much as the Nice lithium and is twice as expensive. That means that if you are not recharging an eneloop more than 4 times in its life (~10years) then you would have been better off with a lithium primary… I wish to find a cheap 9V lithium primary now… (less than $4)

Thanks for correcting the info on the chart (that you test Energizer Lithium Ultimate, not their “Advanced”)

How about shelf life for the NICE cells — anyone seen anything on how long they last?
And, do they keep a decent output when down around freezing temperature?

Those two features of the Energizer Lithium AA and AAA cells have made a big difference for me over the years, for emergency kits and winter camping use.

I note that Fasttech lists the NICE lithium primaries as having the same shipping restrictions as lithium Ion batteries making them a long wait to receive. For those in the USA Battery Junction has Powerizer Lithium Iron batteries though not as good a buy and I have actually found Energizer Ultimates for less each on some sale offers.

I asked Battery Junction on their site and they said, “the P1A is compatible with only Alkaline and NiMh AA batteries.”

I am ordering this light for an elderly female relative and I want to make sure it works when needed. I intend to send the light along with a package of Energizer Ultimate Lithium Batteries. Disappointed at Battery Junction’s lack of knowledge.

beehaven;

Some time ago I downloaded the technical documentation PDF s from Energizer for both batteries and the only real difference is that the Ultimate Lithiums are very slightly better maximum current drain and capacity than the Advanced Lithium batteries. Same chemistry and voltage output.

Here is the link to their You Tube review. https://www.youtube.com/watch?v=gKs2xBpAyAg

I will buy the Energizer Ultimate Lithium Batteries.

Thanks for your in depth review.

Advanced: 10 years
Ultimate: 15 years

The latest packaging for the Ultimate Lithiums now claims 20 years so the link is out of date or has not been updated. I have some of the packs so marked. Per something I read recently some military tests show a shelf life potential closer to 35 years!

I was told my P1A is heating up on high mode because the Energizer Ultimate Lithium are 1.6V. The Product Datasheet states they are 1.5V. http://data.energizer.com/PDFs/l91.pdf

The L91 is initially 1.6+ volts under NO LOAD conditions. In fact the Pulse Response test shows it can when new be as much as 1.8V no load voltage. Note that the 1.5V is listed as NOMINAL VOLTAGE but the graphs show how that varies with time and loads. Under the drain of a LED flashlight it falls rapidly to about 1.5 volts but under the same current draw the 1.5 volt alkaline battery drops to considerably lower than 1.5V as it has much higher internal resistance. The Ultimate Lithium can provide much greater voltage and current under high load conditions, as can the best quality NiMh rechargeable batteries such as Eneloops but the Eneloops do it at 1.2V nominal.

Download the E91 Alkaline battery PDF and compare them. Under any real current load the E91 falls on it’s face. The link is in the Specifications area on the L91 PDF you linked to in your post. The light gets hotter because the L91 is a much higher current capable device that SUSTAINS its nominal voltage under higher current drain conditions. It continues to allow the light to run at the output level that alkalines only provided for a few minutes or less.

I would like to share you comments on the Going Gear P1A YouTube video.

I have been concerned that the senior lady who will ultimately use the P1A light would have a problem using the P1A with the Ultimate Lithium Battery, She lives in a cold climate and the P1A might be left her her car for months at a time. After reading your comments I see that under the drain of a LED flashlight it falls rapidly to about 1.5 volts. I fell confident that the P1A will be able to be used with the Energizer Ultimate Lithium. No harm will come to the P1A or the senior lady.

Thank you so much for all your help. Your explanation was clear and concise. What an amazing forum.
