 LSD is great.... just keep away from heat! January 9, 2007

According to Sanyo, the new eneloop LSD (low self-discharge) NiMH batteries can maintain 85% of its original charge after 1 year of storage. This claim is slightly misleading, because it is based on simulation test at 20 degree C. At higher temperature, the self-discharge rate is likely to be much higher.
I have tested five of those AA cells (details are given in my review for the eneloop 4-pack). The average energy loss is about 26% after less than 6 months of storage. This self-discharge rate is about 3 times higher than what Sanyo claimed. However, it is still 6 times lower than that of ordinary NiMH batteries. Therefore I'm in the process of replacing most of my existing rechargeable cells to the Sanyo eneloop.
This 8-pack Sanyo eneloop LSD batteries is a better value than two 4-pack. Thanks to lower self-discharge rate, you'll discover a lot more applications for eneloop cells in your house, such as in clocks, remote controls and smoke detectors.
But please, don't use them as emergency flash lights batteries in your car, because the higher temperature during summer time will probably nullify the advantage of LSD.

I have tested six new eneloop AAA cells, dated "2006-06'. The average residue charge is 589mAh, and the freshly charged capacity is 827mAh. This implies a self-discharge rate of 29% in 7 months, which is consistent with the rate for AA cells (26% loss in 6 months).
[Update on Jan 29, 2007]
The Rayovac "Hybrid" rechargeable NiMH batteries are now available at Walmart, priced at only $[...] for 4-pack of AA or AAA cells. It is also advertised to have low self-discharge rate, but not as low as that for eneloop. The eneloop is supposed to retain 85% charge in 12 months (when stored at 20 degree C), whereas Hybrid is supposed to retain 80% charge in 6 months (no mention of temperature).
[Update on June 3, 2007]
In my 2-month self-discharge test using four different brands of NiMH cells. Hybrid and eneloop came up neck-and-neck!
Room temperature: 60-62 degree F (16-17 degree C). All capacities measured are average of 2-cells.
- Sanyo eneloop 2000, purchased Jan 2007.
Initial capacity measured: 2070mAh
Capacity after 62 days: 1796mAh (-13.2%)
(Note: my previous result for eneloop showed -18%, but I repeated the test and it did better this time)
- Rayovac Hybrid 2100, purchased Jan 2007.
Initial capacity measured: 2155mAh
Capacity after 62 days: 1859mAh (-13.8%)
- LaCrosse 2000, purchased Jan 2006.
Initial capacity measured: 1902mAh
Capacity after 62 days: 1417mAh (-26%)
- SONY 2300, purchased Sep 2004.
Initial capacity measured: 2210mAh
Capacity after 62 days: 1309mAh (-41%)
So neither eneloop nor Hybrid did as well as advertised, but they are still significantly better than previous generation of NiMH cells. So you can't go wrong with either brand.
Some new facts about LSD cells you should know... January 6, 2007

My original review on the Sanyo eneloop NiMH cells was written nearly two years ago. Since then, I have learned a lot more about the characteristics about eneloop and other low-self-discharge cells. So it is time to clear up some inaccurate information I wrote about eneloop's self-discharge rate.
1. I was told that the Sanyo eneloop cells were not 100% fully charged when they leave factory. This makes sense because new cells are fast-charged in the factory to save time. In order to avoid problem with heat and gas built-up, they cannot be charged to 100%. I have tested some eneloop cells that were manufactured 20 months ago, and they still maintained about 70% charge. On the other hand, cells manufactured 6 months ago contain about 75% charge. This confirmed that the discharge rate is much lower than I previous estimated.
2. The self-discharge rate of eneloop (and other LSD cells) is not linear! My own testing showed that a fully charged eneloop may lose 10% of its initial charge during the first month of storage, but in the second months it may lose just 2-3%. The rate becomes even slower after three months. In fact, my 5-month self-discharge test using various brands of LSD cells gave nearly identical results as my previous 3-month test.
3. When an eneloop cell is freshly charged, its capacity actually measures at about 5% higher than its rated capacity (2100mAh vs. 2000mAh). In my previous tests, I used measured capacity as base to calculate the percentage loss. This results in apparently higher percentage loss. Had I used the rated capacity as base value, the self-discharge rate would be about 5% lower.
Based on the above revelation, I believe Sanyo's claim about eneloop (maintain 85% charge after one year, 80% after two year) to be accurate. Therefore the title of my previous review ("The News of LSD Has Been Slightly Exaggerated") has to be replaced.
Over the past two years, I have tested several different brands of LSD cells available from Amazon.com, including Rayovac Hybrid, Kodak Pre-Charged, and Duracell Pre Charged. They have all performed very well - practically no difference from the Sanyo eneloop. So the bottom line is: just pick which ever brand of LSD cell is on sale, and you can't go wrong.

I received several sets of Eneloops in February and label told they were produced in April - so they sat at warehouse for nine month. I put them into camera and they worked just fine. Kudos Sanyo!
I should also mention that Sanyo includes reusable battery holders with each set of four. These holders do not look very sturdy, but they perfectly usable.
Technically, Sanyo solved the main problem with NiMh technology - frightening self-discharge rate (up to 40% a month for standard cells). By doing this Sanyo reduced cell capacity down to 2000 mAh from today's top line of 2700 mAh.
Simple calculation shows that due to self-discharge a good 2700 mAh battery holds only around 2000 mAh after a month and a half.
So the answer to the question "which battery is better - Eneloop or standard NiMh" - lies in the usage pattern.
If you always keep batteries in your camera in top-notch charged condition, then standard 2700 mAh set is a winner. For occasional shooters who always forget to charge batteries (like me), Eneloop makes lot of sense because in three month I get around 1900 mAh out of Eneloop and only 1400 mAh from the standard cell. So Eneloop is a winner for everyone who keep batteries inside the camera or any other device for more than 6 weeks.
And, well, if paragraph above looks too technical with too many details and numbers - then Eneloop is a clear winner too, because it just behaves the way battery should behave - without forcing users to know how it works.
This observation made me buy additional sets of AAA Eneloops to use in my wireless mouse, keyboard, voice recorder and LCD flashlight. It should be taken into account that Eneloops are four times more expensive than Alkaline cells, so it is reasonable to use them for devices that require fresh batteries at least twice a year.
These batteries are great! September 8, 2007

I bought these batteries for use with my Canon S2 digital camera. I was having trouble with typical nimh batteries because I would charge a spare pair of batteries for use when the main pair died. But I was finding that the ones I charged a few weeks ago would be almost fully discharged by the time I would swap them. This was really annoying and pretty much defeated the purpose of having rechargeables... I had to use alkalines instead. But this new so called 'hybrid'/low discharge technology finally solves this problem. Of course it does not solve it completely because these batteries still discharge over time... just a lot slower, but at least now I know I have a pair of batteries that are at least 80 percent or so charged when I swap them. This technology was actually developed by an small independent company and licensed for use with all the major battery companies now. For instance, Sony is also utilizing it in their new batteries now. To me, this demonstrates how well it works.
So how does it hold up in real life? Pretty darn well, actually. I noticed that these particular batteries last really long in my Canon S2. I haven't had the problem of charged batteries being totally discharged by the time I swap them anymore. So if you're having similar problems with your older Nimh batteries, I would recommend giving these batteries a try. But don't feel limited to this brand, there are many other brands utilizing this technology and I've used other brands with the same great results.
Tip: If you live near a Fry's Electronics, they have a nice selection of battery choices that utilize this technology.
Buying my 4th set April 2, 2007

I was initially skeptical when I bought these but figured it couldn't hurt. I needed a set for my Nikon SB-600 flash. The 2700 mAh Energizers I had performed just fine until they sat in the flash for a month, at which point I had to carry a spare set "just in case". I charged the Eneloops, placed them in the flash and had my first call a month later. They worked wonderfully. I went the whole evening without needed spares. I used them again two months later and got a solid hour or two before they were exhausted. They easily lasted 2-3x as long as the Energizers and where in the flash for 2x as long. All-in-all, they've performaed very well. They may not maintain 85% of their charge after one year at room temp (as one reviewer suggested) but they certainly "sit in the bag" far better than my others. I am slowly phasing out all my non-Eneloops as a result...
