Just about have NO USE for NimH anymore...

[PlayboyJoeShmoe]

Well, non LSD NimH anyhow.

I have 6 C cells I got at Batteries Plus maybe as much as two years ago.

Last time I checked them they were all pretty close.

Now I just checked 'em and 4 hold 1.2V with two at .9V ..... Just effing great!

Indeed, non-LSD NiMH cells are pretty much only useful to people who know they'll use their flashlight (or digicam, or mp3 player...) regularly and need all the runtime they can get. LSD cells are a much better choice for most people. I, for one, no longer buy non-LSD NiMH at all.

 

[PlayboyJoeShmoe]

All I know for sure right now is I need a lot more LSD NimH than I can possibly afford!!!

 

[louie]

Yeah, I've bought batches of several brands of AA NiMHs since they were 1200mAh, and they've all died within a year or so. Except Sanyos, which have held up fine (2100 and 2300 mAh). Just starting on Eneloops....

 

[BlackDecker]

I've thrown away at least 2 dozen 2500mah Eveready AA batteries. After less than 20 charge cycles, none of them would hold a charge for more than 2-3 days. I still have a few 2300mah Eveready AA's which still work fine.

I buy nothing but Sanyo Eneloops and Rayovac Hybrids now.

 

[Templar223]

I hear ya.

Recharging them every couple of months is a pain.

I've sent batteries back to Sanyo for replacement, and the new ones seem better, but like many, I can't recall how many NiMH batteries have gone in the trash.

I'm leaning hard towards going to Lithium rechargeables. Yeah, I know they are more dangerous, but I like the lower maintenance issues.

Took me a min to realize we're talking about "Low Self Discharge", I was wondering what "Limited Slip Differential" meant in the battery world!

 

[Fallingwater]

You see "LSD" and you think "Limited Slip Differential"? You're weird.

 

[PlayboyJoeShmoe]

I was a bit too young for the real LSD, and besides I've always been so straight I could be used as a level!

There are safe Lithium's now. Emoli, A123 now come in 18650 size. Not sure if AA size will be coming anytime soon.

CPF tends to be a bit elitist, I'm the only poster I'm aware of that includes an explanation of acronyms I use, or includes full manufacturer names and codes rather than only referring to a "G2" or an "Elly".

"Lysergic Acid" and "Limited Slip Differential" are the only two LSDs I've heard of previously.

LSD !

I see Pounds, Shillings & Pence.

I also see Lucy in the Sky with Diamonds.

I bought a bunch of AA to C and D battery adapters from DX and use Eneloops in everything. I must say you shouldn't expect "D" runtimes from the AA cells, but they do seem able supply enough current to run various devices fine. I also like that NiMH batteries like Eneloop don't reglularly leak like many alkalines do when left in place for long periods of time.

 

[PlayboyJoeShmoe]

SIGH! It's about time to check my remaining alkaline lights.

And with about 120 total lights there are plenty that still have alks....

snap.

 

[PlayboyJoeShmoe]

I KNEW there was another GOOD reason I put PVC pipe and C cells in D lights!

Found a zero voltage weepy Rayovac C among the 4 in a 3D light.

Either gotta take the batteries out of a BUNCH of lights or get more Lithium AAs and LSD NimH AAs and make adapters.

EDIT: I believe that 3/4" CPVC slips inside 1" PVC to make a decent AA tube. Will check and report.

Further EDIT: Yes 3/4" CPVC will fall through 1" PVC. The use of tape and or rolled paper makes everything fit better. Particularly if you use rolled up paper inside the 3/4" CPVC you get good fit and even if ALK AA leak the goo can't get to the aluminum.

So I just bought another pack of 8's Sanyo Eneloop. From the feedback I gather here, most members seem to be happy with them. For most users, will the lower capacity against the Sanyo 2500/2700 make a difference?

I hope its not necessarily better to wait as Sanyo may come out with Eneloop's with a higher capacity. I wouldn't want to have to spend again just to use the higher capacity if ever. Wonder if it's a marketing startegy to start with low capacity then start selling higher ones later on.

Doubtful. Eneloops have been on the market for 2.5 years now with no increase thus far. One of the things that they do to achieve the LSD characteristics is that they use bigger / thicker components such as the separator plates in the battery, decreasing the space available for the active compounds. Conventional NiMH designs had increased battery capacity by minimizing the volume of the non active parts, and one side effect was increased self discharge.

It would be crazy to say that LSD capacities will never increase, but for now I think they are up against some real technical limitations rather than marketing imposed limitations.
