SANYO’s "Clean Energy Loop" initiative has become a reality. All eneloop 1500 cycle and XX batteries are charged at the factory in Japan using power generated from solar energy.
WHEN IS 1.2V BETTER THAN 1.5?
eneloop꿂onsistently High Voltage Level
The initial voltage level of a battery provides no indication of how long the battery will last or how much power it can deliver. Alkaline battery cells rapidly drop below 1.5V soon after they are put into use and the voltage continues to steadily decline over time.
Since alkaline cells are non-rechargeable, they must be discarded and then replaced. SANYO’s eneloop batteries deliver best-in-class Ni-MH high capacity power and are rechargeable up to 1500 times. Devices like cameras flash units and wireless game controllers can easily draw more than 1000mA of current; rapidly depleting alkaline batteries.
eneloop batteries maintain a consistently high voltage level keeping your devices operating for a longer period of time. When you use eneloop Ni-MH rechargeable batteries, you will realize that “1.2V” can indeed be better than “1.5V”.
WHY ARE ALKALINE BATTERIES 1.5V?
Regular disposable AA and AAA batteries are considered Primary Cells, and are most widely recognized as conventional “alkaline” batteries. There are two electrodes inside each cell; one is made of Zinc, known as the anode (the negative terminal) and the other is made of Manganese Dioxide, known as the cathode (the positive terminal). The electrodes are surrounded by an alkaline electrolyte, the chemical from which alkaline batteries get their name.
Battery chemistry of an alkaline battery generates 1.5V. As the chemical reaction fades, so does the power of the alkaline battery cell. This is why the voltage from alkaline batteries drops off shortly after the battery is put into use and the power continues to fade over time.
WHY ARE NI-MH RECHARGEABLE BATTERIES 1.2V?
Ni-MH rechargeable batteries have two electrodes inside the cell: Nickel and Mercury Hydride. Battery chemistry of an Ni-MH rechargeable battery generates 1.2V. While alkaline batteries experience rapid drops in voltage Ni-MH rechargeable batteries maintain the same voltage throughout most of the entire charge.
The chemical makeup of Ni-MH batteries eliminates the “memory effect”, which means the cells can be recharged at any time without having to be fully discharged.
eneloop batteries have continued to raise the performance bar in Ni-MH rechargeable technology. eneloop has increased “low self discharge” performance on Ni- MH rechargeable batteries which allows eneloop cells to store power for longer periods of time.
WHAT MAKES ENELOOP THE BEST RECHARGEABLE BATTERY
The new SANYO eneloop battery incorporates a highly-durable super-lattice alloy which lessens the deterioration of this important alloy material. This super-lattice alloy increases the electrical capacity of the battery chemistry through lower internal resistance and delivers a long lasting, stable voltage output.
A new strong, thin outer case has also been added to the eneloop battery design in order to improve the internal cell space efficiency. The new case optimizes the balance of the components and when combined with other improvements have led to an increase in the number of times that eneloop batteries can be recharged.
eneloop = LOWER COST OF OWNERSHIP
Wireless game controllers incorporate power-hungry features such as built-in speakers, gyroscopes and motion sensors. Consider the hidden cost of ownership in operating two wireless game controllers.
Let뭩 make the following assumptions:

1. You play video games one hour per day or 365 hours per year, using two remote/wireless controllers.
2. A pair of batteries (either alkaline or eneloop) will provide you with roughly 20 hours of game-play usage time.
3. In the first year, you will need 18.25 pairs of batteries per controller (either new alkaline or recharged eneloops).
4. You will consume 73 alkaline battery cells in one year (for two controllers) compared to only 4 eneloop cells which can be recharged 1500 times ($0.04 per cell).
5. Four AA Alkaline batteries will cost roughly $5.49 MSRP.
6. Four AA eneloop batteries with an AC charger will cost $21.99 MSRP.

Now let’s look at the annual cost of ownership in only the first few years and then extend it out to ten years (at that point, you probably won’t be playing on the same game system). It is quite obvious that eneloop more than pays for itself in just the first year of ownership!
TOTAL ANNUAL COST PER YEAR

RECHARGEABLE BATTERY POWER YOU CAN RELY ON WHEN YOU NEED IT MOST!eneloop batteries deliver dependable power allowing you to maximize your music, gaming, computer, photography and other experiences. eneloop batteries can be used to power these and many more devices.

How to tell the difference between the 뱊ew 1500" and the 뱋riginal 1000?eneloop batteries
It is easy to distinguish between the 1500 and 1000 cycle eneloop batteries. The 1500 battery has a gray top (in the Green/Blue package pictured) and the 1000 (in the Blue/Orange package pictured) has a white top.
eneloop Battery Specifications
eneloop꿚HE BIRTH OF A NEW TECHNOLOGY
For more than 35 years, SANYO has been a leading manufacturer of battery technology. In 2005 SANYO set out to develop a new type of rechargeable battery that would literally change the way people live, work and play. The result was eneloop, a rechargeable battery created with a very simple idea in mind: provide a common energy source that can be reused over and over again. This 뱇ooping energy?became eneloop. Today, eneloop battery cells are recognized by millions of consumers worldwide as the industry뭩 premier rechargeable battery.
eneloop’s “signature features” include ready to use rechargeable power with the ability to maintain 75% of their charge for up to 3 years (when not in use), can be recharged up to 1500 times, they have no “memory effect” and outstanding performance even in extremely low temperatures (down to -4 degrees F).
Americans deposit 8 billion disposable batteries into landfills each year! eneloop batteries can be recharged up to 1,500 times, which means that the purchase and use of a single eneloop cell can keep many hundreds of batteries from entering landfills! They can also be recycled free of charge at any of the 50,000+ Rechargeable Battery Recycling Corporation (RBRC) recycling centers near you.
Usage Assumptions
The new SEC-HR4U8BPN 4-AAA eneloop battery pack utilizes SANYO's advanced rechargeable battery technology allowing them to last longer than ever before! They provide excellent performance-to-cost advantages over both conventional alkaline and other rechargeable batteries. Unlike disposable batteries which can only be used only once and are wasteful to the environment, the new eneloop batteries can be recharged up to 1,500 times. They come pre-charged, can be used immediately out of the pack and maintain 75% of their charge for up to 3 years when not in use. Eneloop batteries deliver reliable battery performance when you need it the most!

Sanyo NEW 1500 eneloop 8 Pack AAA Ni-MH Pre-Charged Rechargeable Batteries

 

Customer Reviews

I have done extensive testing on the original eneloop rechargeable batteries since early 2007, shortly after they were introduced in the US. I have also tested the blue second-generation eneloop cells from the Costco eneloop package back in 2010. But this is the first time I have seen second-gen eneloop in white wrappings being sold in the US. With so much talk about counterfeit eneloop going around, I was understandably cautious when I purchased those SANYO NEW 1500 eneloop 8 Pack AA Ni-MH Pre-Charged Rechargeable Batteries.
I tested four of those cells, using my old La Crosse BC-900 Battery Charger.
- Right out of the package, their average remaining charge is 1568mAh, or nearly 80% of the rated capacity of 2000mAh. The spread is also very small, from 1558 to 1577mAh. This proves that they are indeed low-self-discharge type. (Date code on my cells says "11-01", or Jan 2011)
- After one recharge/discharge cycle, their average capacity improved to 2115mAh
- After two more recharge/discharge cycles, their average capacity leveled off at 2133mAh, or more than 6% higher than the rated capacity.
The above results are very consistent with what I have previously observed, while testing second-gen eneloop cells in the Costco package. Therefore I'm convinced that those are indeed genuine second-gen Sanyo eneloop cells. (See the scans I uploaded to Customer Images section, if you need to distinguish between old and new eneloop cells)
On the other hand, currently the prices of those new eneloop cells are about 25-50% higher than that of the original eneloop cells. So one may question: do the new eneloop cells offer sufficient improvement over the old, to justify the price different? Let's compare the following factors:
- Cycle Life: The 2nd-gen eneloop claims to "recharge up to 1500 cycles", while the original only claims 1000 cycles. This 50% improvement looks great on paper, but note that if you recharge your eneloop cells twice every week, it will take 10 years to reach 1000 cycles. So in real life, most average users will never notice the difference.
- Self-Discharge Rate: The new eneloop cells claim to "maintain 75% charge after 3 years", while the original only claims "80% after 2 years". Again, in real life most people will never notice the difference.
- Capacity: First-gen eneloop AA cells have "Typ 2000mAh, Min 1900mAh" printed on them, while 2nd-gen eneloop AA cells only say "Min 1900mAh". But in fact they have the same capacity rating of 2000mAh (typical) according to official Sanyo web site. My measured capacity numbers are actually around 2100mAh for both versions.
BOTTOM LINE:
Both the new and old eneloop cells are excellent products. You can safely mix and match them in any application, and probably nobody can tell the difference in the next 10 years. But in case you can't decide which version is a better value... Just flip a coin and pick one - you can't lose either way!
[Update on July 31, 2011]
Long term self-discharge data: I have tested a pair of new eneloop AA cells after 104 days sitting on the shelf (the batteries, not me). The average remaining charge is 88.7%. This charge-retention rate is slightly better than that of the original eneloop, but the difference is within margin of error for my experiment.

This package (SANYO NEW 1500 eneloop 4 Pack AA Ni-MH Pre-Charged Rechargeable Batteries w/ Charger) contains four second-generation '1500 cycles' eneloop AA cells, plus the 'MQN06' 4-cell charger
I have tested those new second-generation eneloop cells about one year ago from the Costco eneloop package, and also more recently from the SANYO NEW 1500 eneloop 8 Pack AA. I can honestly say that: while both old and new eneloop are excellent products, their difference in performance is hardly noticeable. Both version have exactly the same capacity rating of 'Typ 2000mAh, Min 1900mAh'. Actual measured capacity, using my old La Crosse BC-900, is actually about 5% higher at about 2100mAh on the average.
Some advertised improvements of the new eneloop cells looked impressive on paper, but not easy to verify in real life. For example, the new cells claim to have 50% longer lifespan (from 1000 to 1500 cycles). But note that even if you recharge your eneloop cells twice every week, it will take about ten years before you can realize the difference in battery lifespan. The new eneloop also claims to "hold 75% charge after 3 years" in storage, while the old one only claims "80% after two year". Again, in real life most users will never experience any difference. But then again, it does give a warm and fuzzy feeling knowing that you are getting the latest and greatest rechargeable batteries on the market. (At least until the 2500mAh Sanyo "eneloop-XX" arrives)
Mechanically, there are some very minor differences between original and new eneloop cells (See my upload in the Customer Images section to distinguish between old and new). Note that there are some confusions about 'vent holes' on the latest eneloop cells. Some poeple even claim that cells without visible vent holes are counterfeits. But I have tested two batches of new eneloop cells with and without 'vent holes', and found them to be identical electrically. So I'm confident that those latest batch I received are genuine.
The Sanyo MQN06 4-cell charger (included in this and many other eneloop packages) is a big let-down. Here's what I don't like about this charger:
- It charges in pairs only. This is very inconvenient for appliances that take odd number of cells. If you try to charge an exhausted cell together with a half-full cell, the charging process stops as soon as the second cell is full, which means the first cell is still half-empty.
- The charging current is very low: 300mA for AA cells, 150mA for AAA cells. That means it take about 7 hours to recharge a pair of exhausted eneloop AA cells.
- If you leave a pair of charged cells in an unplugged MQN06, there is a leakage current of 0.5mA. This means a loss of 12mAh per day. In other words, a set of 2000mAh cells will become exhausted in about 5 months. That wipes out the 'low-self-discharge' benefit of eneloop cells.
CONCLUSION:
Over the past four years, I have found the original Sanyo eneloop cells to be the most consistent and reliable NiMH cells I have ever used. So I can recommend the new eneloop based on my past experience. On the other hand, I find it inexcusable that Sanyo continues to bundle the best rechargeable batteries with such a mediocre charger. So you may want to consider a package that comes with a better charger, such as the Sony Cycle Energy BCG34HRE4KN, and then buy more Sanyo eneloop cells as needed. This SONY charger can handle each cell individually, and it can be used to recharge any other brands of LSD cells.
