Question for Steve Harris (or anyone else) ENELOOP VS ENERGIZER
« on: January 07, 2014, 02:16:56 PM »
A couple months back, Steve said that he was putting some new batteries through their paces that could outdo the Eneloop.

I was wondering if there are results back from that battery of tests (no pun intended) and which ones came out on top?

Thank you.

I recall Mr. Harris mentioning something about "Bad bunny" and I have avoided Energizers since.

You're right, I think it was Eneloop vs Rayovac and not energizer.

My experience is that energizer are junk.  I bought AA, C, and 9v.  None of them hold a charge worth a damn.  I can't speak on eneloops but they are next months "prep" buy.

If I recall correctly, while Steve liked the Eneloops for AA and AAA, he was down on the adapters.  Just not enough juice there to last very long.  I don't recall what he recommended though.

Seconding this. My Eneloops last noticeably longer than my Energizers. I'll be replacing them all with Eneloops soon.

that was my thought, you have the size of the C and D, but not the power... i though enloop made C and D sizes, but i guess it's just the adapter.

I'm in to see the response on anything better.

I've been using Eneloop AA and AAA for years now without any issues.

I was in the market for some Cs and Ds for kids toys and soothers and such. And I knew the adaptors that would allow the use of AAs in place of Cs just wouldn't last long. The capacity just isn't there. So after some research, I picked up some Tenergy Centura Low Self-Discharge size C and size D batteries. They work great and I don't have any complaints at all. No issues whatsoever. They are highly recommended. I probably have about 10 each of the Cs and Ds that I use and rotate through toys and such. Highly recommended.

After I had such good luck with the Tenergy Centura Cs and Ds, I thought I would try out their AA and AAA. I am no expert and don't have any official tests, but they work *almost* as well as the Eneloops. But then again, they are not quite as expensive. What I do is the good stuff that I want to last awhile, like my digital cameras and flashlights, I use the Eneloops. For the kids toys and remotes and stuff, I use the Tenergy.

This is just my opinion, but I hope that helps!

Tenergy rings a bell.  I think those might be the ones Steve recommended.  That was a while ago though...could be something new since.

Just did a price comparison and Tenergy is $10 less for a 4 pack of AA. The two at an equivalent power output level are neck and neck.

Time for me to battery shop.

I use Tenergy and ENELOOP Aa and AAA cells , after 4 years I have had some failures in Tenergy,NO failures with ENELOOP cells...BUT SANYO sold ENELOOP to PANASONIC and and The 2100 cycle cells appear fine BUT the 2500 rated cells appear to have a problem..

Any others note the change lately?

Just swapped out two AA in my mouse yesterday.  I had a rack of Eneloop and Energizer AA batteries that were all recharged at the same time together about 6 weeks ago.  the Energizers were dead already, would not even power a mouse.  The Eneloop AA batts were good to go.  I knew from prior experience they were much better but this is pitiful for Energizer.  I just tossed all those as worthless.

I gave all of my non-ENELOOP cells to my brother...made TWO people happy at one move.

I can't seem to get that last short video Harris made. He showed some different AAs he was researching. He said they looked better than Eneloops so far, but was still testing. Can anyone recall which batteries they were?

My link to that video doesn't seem to work anymore.

  My choice is ENELOOP,the only failure I have seen was when a charger failed and cooked a set of 4 AA cells till they leaked.
The 2000 MAH ones tend to perform better than the higher rated 2550 and 2850 ect ENELOOP as they don't produce power for higher Current devices (1/2 amp or more) as well or as long as the 2000 MAH versions. The higher rater cells may be just fine for devices that use little power but I try to simplify for my use and the 2000 MAH ENELOOP does just fine.

  I do like the TENERGY 9 volt,C and D cells and am tempted to try TENERGY Low Self Discharge cells ,but with no failures of my ENELOOP AA and AAA cells I hav not felt the need ...as of yet.

let me have a look in the big flashlight forum for any new additions. But for now nothing bests eneloop. Duracell has LSD but it seems they are suspiciously similar to Eneloops in make, same for other makers....
Early in the game Uniross Hybrios were a little bit notch better, but that stands to reason since Eneloop bought the technology from them.
My bet is that Harris did not find any better, else he woudl have spoken.

If price is a factor, my local Best Buy had kits with 8 AA and 4 AAA Eneloop plus charger on sale for $20. I bought them all, but hopefully the stores near you may have some.

This thread hasn't been active in a while.  I recently bought some AAs to compare.  I bought 4 new Eneloop gen 4s, 4 Amazon Basics, and 4 Energizers.  I also have some not too old EBLs I will add to the testing.  I am still in the process of testing so no definite conclusions so far.  Right now I am running the cells through a couple conditioning cycles.  With a constant 1 amp load the Eneloops showed the lowest capacity, excluding the EBLs which I haven't got to yet.  I suspect the EBLs will test lowest from previous tests.  Once I get everything reconditioned I can draw some real conclusions.

I still like Eneloops but can't help being curious about other brands.  I really didn't need to buy more cells since most of them sit around waiting for their turn to be used.  One interesting thing which confirmed a long suspicion of mine was reading Eneloop's own writeups on their batteries.  They briefly mention 'memory' of NiMH batteries.  They did not say there was none, but rather that their battery had a higher voltage output which compensated for it. They also mention how crystals form in the cell causing the effect.  So, perhaps that is part of the reason my tester is spending hours reconditioning all the batteries I want to test.  I can see on the graphs how the capacity goes up after a couple cycles, in some cases by quite a bit.  I'll try to post the graphs once the real tests get done.

I got through some tests comparing Eneloop, Energizer, Amazon Basics, and EBL cells.  The results were confusing, cells of the same type varied quite a bit, and similar results between tests.  I used the same charger at 500mA.  While all the cells have been through a number of cycles, maybe they need a few more to stabilize.  I did not have my CBA when I first starting using Eneloops so I dont have anything to compare with.  I did my best to treat all the cells the same way to eliminate that variable.

One thing which did seem to come out of the tests, but under suspicion pending further tests is that with a 1 amp discharge Energizer and Amazon cells had a higher capacity than Eneloops.  Of EBL 2300 and 2800 cells, the two test quite close.  At 1 and 2 amps none of the cells measured at the manufacturer's rating.

I was hoping to see some pattern out of the tests but that didn't quite happen.  Since a few different brands of new cells seem to have the same 'breaking in' issue my guess is it must be something common to NM cells.

For now I am going to start using the test cells in flashlights so they get some real world use and revisit the tests after that.  Since older cells test consistently my best guess is that it takes more cycles than I thought for a new cell to become 'conditioned'.  If anyone has any ideas or information about new cells I would like to hear it- or suggestions on a test to run.

What are you using to hold the cell and make contact with the test leads?  I’ve had a lot of spurious results from flakey contacts when running tests with my CBA.

ralph, the 1&2 Amp discharge seems a bit too much to me....
Did you check the datasheets for what the manufacturers use?
(many times the stated capacity is of a lower discharge rate)

I am using magnets to make battery connection.  They work well except when I accidentally bump them.  The discharge rates I have been using are high, in part to keep the test times down so I can get through a test and not leave the dead cell connected to the CBA for hours until I get back to it.  I did run a power profile test out of curiosity and all the cells pretty much give out by about 3 amps load, so 2 amps is pushing them.  The CBA set for a NMH battery of 2AH suggests a load of 2 amps. 

I didn't check, but have no doubt the manufacturer's test load is much lower, 0.1C if I had to guess.  I am still curious enough that I'll run some tests at 500mA.  That should run about 4 hours per cell so it'll take a while.  I'll probably run one cell of each type to see how they compare.

I eventually tried clamping over the top of my magnetic contacts and the extra pressure made a noticeable difference in my case, especially in high draw situations.  I eventually modified a woodworking clamp with heavy copper contacts and 10 gauge leads, basically the same thing WMR sells, and my results got more consistent.
