I hope this information will help someone choose AA batteries.
Alkaline: Premio (cheap alkaline) and Duracell Procell.
NiMh: Eneloop 1900 mA and Eneloop 2400 mA.
Primary Lithium (1.8V): Energizer Lithium and NICE Lithium.
For testing I have selected a reliable AA flashlight Klarus P1A
Official Data KLARUS P1A:
- Two output modes: ——Max output: 150 Lumens/ 1.5 hrs ——Low output: 11 Lumens/ 28 hrs
- Working Voltage: 0.9V – 1.8V
- Battery: 1pc 1.5V AA (Alkaline, Ni-MH)
There are interesting results.
I hope that this information will serve to help someone.
Greetings to everyone

Wow, the NICE on actually is fairly nice.
Where did you get it from?

Hi.
Fasttech purchased cheaply.
I was surprised by the good competition with Energizer. :bigsmile:
Are these the NICE batteries ?
My Paracord Stuff
YES
Added to my cart, so they will be in my next order with Fasttech. I'll test them to provide some actual mah numbers.

It will be interesting.
I still hope for a decent charger to measure capacity. I’m waiting for the arrival of a BC-700.
Thanks for this review mate, I was waiting to see if the NICE cells were ok, and i guess so!
WOW!!! Thank for the test Trevi_lux… I will order the Nice lithium from FT right now!

Hey Trevi_lux…
What is the no load voltage of the Nice cells before using them (when receiving them)?
(fastech says 1.5v Lithium. If I am not wrong, Lithium primary are 1.7volt)

thanks for the test and efforts!!
as we learn and knew no surprise our P1A is regulated §$%&!ly

The “Nice” received from Fasttech, are above 1.8V (1.82-1.83V)

I have the Klarus from a year ago and I used little. But I think I’ll put in the car with a lithium inside
Anyone tested these Enelong ?
I read comments at Taobao site, some said are good batteries. I might try a pack since I’m filling FastTech cart with one of these.

Wow! Impressive! Thanks for testing and posting! Gonna have to pick me up some Nice batteries!

+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

*+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.
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)
My English isn’t perfect but I’m trying to improve it. If you see something that doesn’t sound right or is just plain wrong, please feel free to point it out!
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!
