Please explain Eneloop to me!

[kramer5150]

I'm not sure what you mean, but I think that these Energizers are regular, non-LSD NiMH cells. If they are, they don't have any "LSD characteristics", as we normally understand them.

From what I read, the main difference making Eneloops able to discharge slower than regular NiMHs is caused by changes in the cathode alloy (elimination of Co and Mn). There are other minor differences but this difference in chemistry is the most important. If the battery doesn't incorporate it, it is an non-LSD NiMH. It may self-discharge somehow slower than higher capacity cells but definitely not as slow as LSDs.

I re-phrased what I typed earlier... thanks.

Got home and checked, that's what I have :rolleyes:

Poor you...

 

[benhar]

Poor you...

That bad, huh?

 

[darknessemitter]

That bad, huh?

Yeah, unfortunately. A lot of people have reported problems with the Energizer 2500's. Mainly they tend to self-discharge even faster than other normal-chemistry NiMH's, and their true capacity is rarely even close to 2500mah.

Well that explains a lot. I tried using them in my Halo paintball loader once, and it didn't work out so well for me. Since then they pretty much stay in my UK flashlights and Wii remotes (but I think kramer5150 has the right idea about putting eneloops in the Wii-motes instead).

Within 3 weeks of being charged my Energizer 2500's would not fire my digital camera up. Totally useless as spares. Eneloops will work even after 6 months, which is as long as I've tested them.

Yes they are that bad. I literally threw mine out. Engergizer sent me a $10.00 coupon for my trouble.

It isn't that alkalines won't work in the Quark.
I just wouldn't use maximum/stobe with a AAx2, (and also omit high for the AAx1)
They are cheap, but one cell rupture and you will have to start replacing components, and the Quark parts are pricey.

Energizer 2500s will actually develop self-discharge rates so incredibly fast, that if you don't use them RIGHT off the charger, they will not deliver anything close to their rated capacity. Mind got so bad that all it took was 48-72 hours to go from full to pretty much dead. They left a bad taste in my mouth for NIMH. Eneloops have been so good to me that I'm not sure where to begin the praise.

A: I don't care to spend time with break-in or re-fresh cycles.
B: I don't even own or can afford a charger to maintain NIMH properly in.
C: I'm using a charger that costs ~$25
D: I don't pair them, I don't match them, I don't keep track of them in any way.
-Bottom line: I do everything you shouldN'T do with NIMH cells if you want them to keep working...

It's been over a year now IIRC, all my eneloops are performing their duties without any issues. the only NIMH cell I've owned that has actually worked for me, and not the other way around.

Eneloop is undisputed leader of NiMH cells.

When Sanyo comes out with a new cell called the "ultralooper" can we count on your continued support?

have to change your screen name and everything...

ouch.

That was a little unnecessary. The thread went a little off from what I intended and became a generic answer, but my primary question was the peformance of enloops in the flashlights. Looking at the hits in that link, I didn't see that.

I may be new to these forums, but I'm not such a complete idiot that I can't search. I didn't see anything initially that answered my question, and I don't have an hour to spend looking through all the threads. This may not be a chat room, but it is a forum, where people shouldn't be afraid to post a new topic without being hammered.

For the record, I didn't "hammer" you, nor did I say you are a complete idiot that cannot search. Sorry you took my comment in such a negative manner.

Didn't even see that there is a battery forum :ohgeez:

I simply took note of your earlier post, and then additionally underscored the incredible amount of useful information that has already been presented regarding the Eneloops on this battery forum that one would miss if they started a new topic in an unrelated section.

I'm the sweetest guy on the forum. Never controversial or confrontational. Ask anyone. Also, :welcome:

Seriously, I'm glad you got the help you wanted. Peace! ;)

In that case, my bad. Guess I took it the wrong way :oops:

FWIW, after I found out about this battery forum I looked it over, and if I had found my answer I would have deleted or edited my question. I do try to research before asking stupid questions :)

Thanks for the welcome!

I second Lux, he is very helpful and has contributed quite a bit to general knowledge here.

If you're nice to him he may give you one of his rust stained white shirts.

:welcome:

Thanks for the second welcome!

I feel a little sheepish now! I've just seen so many jerks at other forums that are ready to pounce on the newbie that didn't use the search, I guess it was easy to misinterpret the "tone". Or maybe I just assumed he was Lex Luthor's brother and thus evil :laughing:

Anyway, I'm glad that wasn't the case. I like forums with friendly atmospheres. That's what keeps people coming back after the technical questions are answered :D

The new Duracell pre-charged bateries are Eneloop rebrands. Same cell construction, both made in Japan, just different labels. I use these since they are much easier to find locally.

My favorite cell is the new 8X Enegizer Ultimate Lithium. Even my TK40 is very lightweight with 8 cells, plus they last forever...

I have a TK40 on order and was all set to use Eneloops in it.

You are saying you prefer the EUL Li because they are lighter and last longer - yes?

Any disadvantages to the 8x eul?

 

[MichaelW]

$, Dollar signs.

 

[Marduke]

Any disadvantages to the 8x eul?

A battery change costs $20 instead of $0.02

Then the Energizer 8x lithium is not rechargeable?

Does it pack more mAh than an Eneloop?

He (4X4Dodge) was saying that the Energizer lithium AA primaries were lightweight and lasted "forever." Keep in mind that he uses the forever term as a metaphor for saying they last quite a bit longer than alkalines or rechargeable NiMh. Primary lithium cells (not lithium-ion rechargeable, to be clear) are light weight by nature. When you're talking about 8 of them, it's certainly a difference that can be felt. As I mentioned in another thread, lithium primary batteries are good to have in storage as back-ups since they have great shelf life. Frequent flashlight users still benefit from rechargeables and they're still the best option in a high drain application like the TK40.

Correct, the energizer 8x lithium, is non-rechargeable and has the same chemistry as a Surefire 123 cell. It does pack more real world mah than an Eneloop but I don't know off hand what the rated capacity is.
