sanyo 2300 vs. eneloop discharge

[vio765]

i came across sanyo's eneloop websight and pondered something. we all know eneloops are LSD cell and sanyo's 2700's have the highest nimh capacity. here are my observations:

eneloops: lower capacity, LDS
2700s: high capacity, fast discharging.

Here are my thoughts:
after 3-6 months, which would have the higher capacity?

Good Grief . . . .


You are very optimistic to expect ANYTHING from non-LSD NiMH cells after 3-6 months.


Eneloops are the way to go. :thumbsup:

If I remember correctly, the break even point is around 5-6 months. After 5-6 months, the LSD has the advantage.

Presumably, a lot is age-dependent?

High capacity cells in general would tend to increase in self-discharge over time, some pretty slowly, some dramatically depending on their nature and usage pattern, so the answer to your question could be hard to be sure about.

good high capacity cells might still be the winner,
but with every 4-pack of any normal Ni-Mhs, there is at least one that is a total bummer.
Often a 2nd one also, that gets bad within 1 years use
(at least thats my personal experience over the last years)
PS: I have one good and 1 very good (=expensive) charger, so its not the equpiment

with Eneloops, or my other LSDs, there was no such behaviour, they all are very similar and working

In my experience non-LSD AA cells are practically empty only a month or so after fully charged.

As uk_caver mentioned, how they are used has a lot to do with it. In my experience, with approximately one year old eneloops and one year old Sanyo 2700's, after about 5-7 days, the eneloops had more capacity. These cells were used for the most part, at medium to high current loads . I would imagine if the 2700's had been subjected to only light loads, they probably would have fared better.

i am trying to decide which cell to leave in the light that i keep in my car. my eneloops and 2700s were purchased and used in the same manner: medium-loads

Well, in my car, I keep a Streamlight TT-1L. Not much of a light, but works pretty good for a "car light". It still has the original Duracell CR123A in it, that I installed when the light was assigned that duty over 4 years ago. I also have a spare Sanyo CR123A along with it.

For emergency lights like that, I figure lithium primaries are the way to go. I've considered exchanging the TT-1L with a Fenix L1P that I have, and installing an Energizer L91 in it, with like spare.

Why does the thread title have 2300 in it?

Umm, typo maybe?

Torch, why is it, that it takes somebody that walks around upside down all day to catch stuff like this?

When we've just woken up and are still full of beans, you real upside-downers are tired from a long day, bored, and go online to "just see what's happenin' on CPF" ... and end up starting a thread. :santa:

And by the time I got to this thread I couldn't add anything constructive because it had all been said already by people the other way up in an earlier timezone.
