8-Pack Long-Lasting 2200mAh HYBRID AA Ni-MH Rechargeable Batteries w/ Latest Hybrid Technology Review

Average Reviews:

(More customer reviews)These were great for the first six months, but then started to degrade significantly after that. I use the top-of-line slow recharger from MAHA, and even with attempts to revive them two of four wouldn't hold a charge and my camera wouldn't even turn on with the batteries fresh from the charger.
The weight of these batteries gives you some sense that these could be subpar made - when I compare the weight of these batteries in-hand with those from another manufacturer I noticed these have half the weight of other AAs. I recommend the Green hybrid series from Sony or regular NiMH batteries from from Panasonic or Sony (orange series) that have

Sanyo eneloop HR-4UTG-4BP - Battery 4 x AAA NiMH 800 mAh Review

Average Reviews:

(More customer reviews)I've traditionally maintained both disposables for electronics that slowly run down the battery, and rechargeables for everything else.
Eneloops now take care of all my needs. The flashlight still works after sitting in a drawer for months and high discharge items need less charging too... thanks to the low self-discharge rate.
Because these have such a low discharge rate spare batteries don't need to be permanently tethered to the charger. Just charge them and set them aside until needed... you'll save a bit of energy by unplugging your charger too.

Kodak - Battery 4 x AA NiMH Review

Average Reviews:

(More customer reviews)The Kodak Pre-Charged AA NiMH belongs to the latest generation of low-self-discharge NiMH cells. It may not be as well-known as other brands (SANYO eneloop, Rayovac Hybrid, Duracell Pre Charged) but it is just as good according to my own testing:
1. The battery capacity is specified as 2100mAh. But the average capacity I have measured (using my La Crosse BC-900) is actually closer to 2200mAh!
2. After three months in storage, the capacity lost is only around 10%. This is even better than the results I got from eneloop and Hybrid (both close to 15%). Note that the difference could be due to measurement error and different ambient temperature, since those cells were not tested during the same period.
I have used more than a dozen of those Kodak Pre-Charged AA cells in digital camera (Canon S5), external flash (Canon 420EX), plus various toys and gadgets with great satisfaction. This Kodak 4-pack is an excellent buy, especially since it can be found at lower prices than other brands of pre-charged cells. If you are also looking for a fast and compact travel charger, then I highly recommend buying it with the KODAK K6200.
However, there are a few caveats when buying or using those Kodak Pre-Charged cells:
1. Make sure those cells are in WHITE cases. Avoid other Kodak rechargeable cells that come in green or grey cases, as those are not "Pre-Charged".
2. Those cells are slightly fatter than ordinary alkaline cells. Most appliances have no problem accepting them, except for my Microsoft wireless keyboard which has a very tight battery compartment. In this particular case, I have to use Hybrid AA cells since they are slimmer than others.
3. Many vendors here offer this product at a low price, but then charge you ridiculous amount in shipping and handling. If possible, wait for it to be available directly from Amazon, and order it with free "super-saver" delivery.
[Update on Nov 28, 2010]
I have confirmed that 'Kodak Pre-Charged' cells are in fact rebranded GP ReCyko+ Pre-Charged Batteries. The latter can now be found at about 50% lower cost!

Rayovac I-C3 15 Minute NiMH AA Size Carded 2 Pack Review

Average Reviews:

(More customer reviews)I read about Rayovac's patent on the I-C3 technology before this product came to market and naturally I was skeptical. A few months after it came to market I decided to try it out.
For over 6 months I've been using these batteries in our toothbrushes, cameras, electric screwdriver, remote controls, two-way radios, CD players, anything that uses AA or AAA. The product exceeds my greatest expectations.
Disregard the high cost comments. This should be viewed as an investment. I can get the batteries locally for about $3.45 each. Figuring 25 cents for an alkaline battery you recover the cost after 14 recharges. 120 recharges and you've paid for the charger.
My family loves this thing. It completely changes your view of battery operated appliances. Not one of these batteries has gone bad. I have a pocket radio that I use constantly. One charge lasts over a week. The batteries do not die suddenly. When in doubt I can top off the battery in less than 15 minutes.
We are never out of batteries and we have an entirely new mindset now that it doesn't cost anything to discharge a battery. At the same time we aren't throwing batteries in the trash can.
It is our view that a battery that costs 25 cents plus shipping and handling per use is far more expensive than one that costs 15 minutes.

Rayovac's patent-pending I-C3 technology (In-Cell Charge Control) puts the control of the recharging into the battery, instead of the charger.

SANYO Eneloop Spacer Packs with 2 AA with 2 D-Size Spacers Review

Average Reviews:

(More customer reviews)The two rechargeable batteries in this package (SANYO Eneloop Spacer Packs with 2 AA with 2 D-Size Spacers) are the best-quality low-self-discharge NiMH cells currently available. The two spacers are made of high quality plastic without any rough edges, and they looked great. The price is also very reasonable. So normally I would call this a good deal. However, if you intend to use them in appliances that accept D-cells, please beware of the following limitations:
1. The capacity of each eneloop AA cell is just 2,000mAh. In contrast, capacity of a typical alkaline D-cell (such as the Energizer E95) is rated at around 20,000mAh when delivering a low current of 50mA. For a larger load current of 500mA, its capacity drops to around 10,000mAh. Still, this is five times the capacity of eneloop AA cell. What this means is that: you need to remove and recharge your eneloop cells five times more frequently, compared to when using alkaline D cells.
2. The base of the D-spacer is hollow. It uses the negative terminal of the AA cell for contact. The battery compartment designed for normal D-cells typically have much larger springs, so the base of the AA cell may fail to make contact with the spring. Check the picture I uploaded to the Customer Image section, and you'll see what I mean. This problem can often be solved by inserting a copper penny or nickel between the battery base and the spring. But it does not always work.
There are some other rechargeable D-cell options available. For example, consider the Rayovac Platinum LSD NiMH D cells. This package is currently priced similar to the eneloop package, but it gives you two real D-sized cells, with 50% higher capacity (3000mAh vs 2000mAh). The down-side is that you'll need a battery charger that can handle D-cells.
If longest run time is your first priority, then consider buying full-capacity D cells such as the 9500mAh IMEDION D Rechargeable Batteries. Those are priced 3-4x higher, and you need an expensive charger that can handle full-capacity D-cells. (Most low-cost chargers cannot fully recharge cells with capacity over 3000mAh)
No matter which option you pick, using rechargeable batteries will save you money in the long run. You just have to know your batteries' limitations, and set your expectation accordingly.

Rayovac Everyday-Use Low Self Discharge NiMH AA Size Batteries, 4 Pack Review

Average Reviews:

(More customer reviews)Talk about a confusion campaign! Currently, you can find not one, not two, but FOUR different series of low-self-discharge ('Pre-Charged') rechargeable cells from Rayovac:
- The original 'Rayovac Hybrid' (LD715),
- The 'Rayovac 4.0' (RF715-4C) with ambiguously titled 'Lithium Technology',
- The Rayovac 'Pre-Charged' LSD NiMH (LD715-4OP), and
- The newest 'Rayovac Platinum' LSD Series (PL715-4).
The 'OP' (Opening Product) series offered here is typically priced lower than others. But its rated capacity is very low at just 1400mAh. By the way, you'll not find this capacity number printed on the battery or on its package, not even from the official Rayovac consumer web site. I have to go to 'Rayovac Industrial dot com' to dig up this information.
I have tested four of those 'OP' AA cells, using my old La Crosse BC-900 charger/analyzer. The measured average capacity is slightly higher at around 1500mAh. But note that all other Rayovac LSD series are rated (and measured) at 2100mAh.
Bottom line:
You may pay slightly less for those 'OP' LSD cells, but the capacity you get is also 1/3 less. Worse yet, this capacity number is not marked on each cell. So if you ever mix it together with other LSD cells, it will drag down the capacity of the whole set. Avoid this product if possible.
[Update on Oct 18, 2010]
I can think of one application where the lower capacity of 'OP' cell is an advantage. You can pair this 1.25V NiMH cell with a 1.65V NiZn cell, to get almost exactly 3.0V out of two rechargeable cells. It is important to select two cells with the same charge capacity (1500mAh), to make sure they run down at the same rate. The down-side is that you need two different chargers to recharge your batteries.
[Update on Nov 20, 2010]
Tested a pair of Rayovac Pre-Charged AA cells after three months on the shelf. The remaining charge is about 87%. This is in line with the self-discharge rate of Rayovac Hybrid.

Zeikos ZE-4PC Precharged 3000mAh AA NiMH Batteries Review

Average Reviews:

(More customer reviews)The product description of Zeikos ZE-4PC Precharged 3000mAh AA NiMH Batteries sounded truly fantastic. On the package it claims Zeikos R2U batteries are "Precharged and Ready to Use", have a capacity of "3000mAh", and a lifespan of "1200 cycles". This advertised capacity is nearly 50% higher than that of other low-self-discharge batteries (typically rated at 2000-2100mAh for AA). That's why I just HAVE to give it a try.
Well, as the old saying goes: "If it sounds too good to be true, it probably isn't"
First sign of warning: I measured those batteries' terminal voltage as I received them. One cell was unusually low at just 1.23V, which means this cell is nearly exhausted. The other three were around 1.27-1.28V, still too low for low-self-discharge cells. In contrast, all name-brands LSD cells I have tested (Sanyo Eneloop, Rayovac Hybrid, Duracell Pre Charged, GP Recyko, etc.) arrived with at least 1.30V.
Next, I measured the remaining charges in those Zeikos cells, using the REFRESH function of my old La Crosse Technology BC-900 battery charger/analyzer. The one cell with lower voltage contained only 114mAh! The other three ranged 637-879mAh. The average remaining charge is only 589mAh, or below 20% of the rated capacity. In contrast, all other name-brand LSD I have tested arrive with at least 70% of rated capacity.
I then continued to run those batteries through the BC-900's REFRESH operation. After one more Charge/Discharge cycle, the average capacity improved to 1361mAh. After yet another three more cycles, the average capacity leveled off at 1655mAh, or just 55% of its rated capacity.
Not willing to give up yet, I then put those Zeikos cell through the 'BREAK-IN' function of my Maha MH-C9000 Advanced Battery Charger/Analyzer. Even after that, the average capacity only improved marginally to 1789mAh, or just below 60% of advertised capacity. The spread in capacities is also quite large, varying between 1688 and 2010mAh. In contrast, all other name-brand LSD cells typically have their capacities measured at about 5% HIGHER than rated vales. Their capacities are also more uniform, with only 2-3% variation.
SUMMARY:
I have tested at least one dozen different brands of low-self-discharged NiMH cells, and those Zeikos R2U cells are absolutely the WORST. They are not "Precharged and Ready to Use" as claimed, and their measured capacity is below 60% of advertised value. In short: Avoid at all cost!

Rayovac Rechargeable NiMH Batteries, AA-size, 8-count Carded Pack Review

Average Reviews:

(More customer reviews)The latest family of Rayovac rechargeable NiMH batteries are all missing one thing: the capacity rating. Previously, you can see the charge capacity (such as '2500mAh') marked on every package and also on each cell. But newer Rayovac rechargeable NiMH cells are just grouped into three classes ('Everyday-Use', 'High-Energy' and 'Hybrid'), with vague claims such as 'Up to 275 photos' printed on their packages.
Of course, those claims make very little sense to us, because Rayovac never tell us which camera was used, and under what test conditions were those photos taken.
After a lot of searching, I was able to find the spec sheet for those cells from rayovacindustrial dot com:
- NM715-4OP 'Everyday-Use' AA, 'Up to 275 photos': capacity=1400mAh
- NM715-4B 'High-Energy' AA, 'Up to 375 photos': capacity=1900mAh
- LD715-4A 'Hybrid' AA, 'Up to 400 photos': capacity=2100mAh
The item offered here is the NM715-8OP (the 'OP' stands for 'Opening Product'). It has the LOWEST capacity amoung all Rayovac NiMH batteries. I have tested some in my La Crosse BC-900 Battery Charger, and the average capacity is actually higher than spec at 1500mAh. But this number is still very low by today's standard for NiMH AA cells. So although the price looks attractive, this is just not a good value.
As of this writing, this 8-pack (NM715-8OP) is actually priced higher than two 4-pack (NM715-4OP). Furthermore, the Rayovac 4.0 AA 4-PACK is available at even lower cost. Those are low-self-discharge cells with higher capacity of 2100mAh. So it is a no-brainer which package you should buy.
[Update on July 16, 2010]
I recently discovered a hidden benefit of those Rayovac 'Opening Product' AA cells: they are exactly the same size as alkaline AA cells, while other NiMH cells with capacity 2000mAh or over are all slightly thicker. So for some appliances with extremely tight battery compartment (such as the Rayovac Sportsman Xtreme 1W LED Flashlight), those are the only rechargeable cells I can use.
[Update Sep 4, 2010]
As if the offerings above is not confusing enough, Rayovac has now discontinued the 'Hybrid' series, and replaced it with another two types:
- LD715-4OP 'Pre-Charged': capacity=1400mAh
- PL715-4 'Platinum Pre-Charged': capacity=2100mAh

Yuasa Enitime AA Pre-Charged Rechargeable Batteries (4-Pack) Review

Average Reviews:

(More customer reviews)GS Yuasa is a Japanese company that makes batteries mostly for sport vehicles.
My Enitime AAs came pre-charged with my new universal remote control. "Technology from Japan - Made in China". So far, performance is comparable with my other low discharge batteries.

Pros:
-For a rechargeable battery, these batteries does not need to be charged before you use it for the first time; right from the packaging into your gadgets.
-They last a long time.
-Does not need special charger. You can use your existing NiMh charger.
Cons:
-After having these batteries for sometime, comparing this set with other brands (Eneloops, Duracell), this set charges less juice.
-This later technology is still expensive.

Sanyo eneloop HR-3UTG-8BP - Battery 8 x AA NiMH 2000 mAh Review

Average Reviews:

(More customer reviews)As a professional photographer and environmentalist, I simply have to use rechargeable batteries, or I'd be throwing out AA's in large quantity.
In the past I've been unhappy with rechargeable batteries, they eventually held less of a charge and when stored, simply ran low and failed me when I needed them most.
These are simply the best AA's that I've used. I have lots of standby equipment.. strobes, back up cameras and associated equipment. I need things to work at full power for the longest possible time. The eneloops have a long shelf life once charged and this is very helpful.
Another plus, is that with photographic equipment, I was able to take far more photos on a single charge and my off camera strobe has a much faster cycle/recovery time than expected with rechargeables.
They are heavier than copper top AA's, I actually weighed them to compare... just an interesting fact. My aux battery holder uses 8, strobe uses 5 and the MBD-10 from Nikon uses 8, so battery weight plays. But the performance has become all I care about... that, and the fact that I'm not throwing away batteries after ever big event shoot.
I also appreciated that they arrived fully charged in their pack, so opening a new pack doesn't mean waiting to charge them prior to putting them into service.
I can't vouch for how they perform in other devices, but can certainly endorse them for photography.
Long shelf life, rechargeable, top performer...

Average Reviews:

(More customer reviews)These are the best AA & AAA batteries I've ever bought. The mfg's claims that they hold on to a charge longer are basically true... far longer. The other "higher capacity" batteries I've used haven't given me as much usage between charges as these Hybrid types, so I am very satisfied.
What would have made them perfect is if I could have bought a smart charger (the kind that can charge in 4 hrs and handle single cells, not just pairs) bundled with them.

Power2000 AA Rechargeable Batteries, 1.2V Ni-MH, 2900mAh, 10 Pack Review

A camera flash really puts AA batteries to test. I have used brands such as Sanyo, Lenmar, Energizer, all with varying results. One aspect I constantly measure is the cycle time of the flash unit which is a direct test of battery stamina and performance. With these power2000 batteries in my flash, I see virtually no lag between shots even after 100 flash bursts, they just keep on reenergizing the internal capacitor an an unbeleivable rate.
