Average Reviews:
(More customer reviews)I almost did not buy these batteries 1 year ago based on a review criticizing their size (too long or so). In the end I bought a set of 8 AND I CAN TELL YOU THAT THEIR SIZE IS NOT A PROBLEM based on my experience.
I use a battery charger that does not use springs to recharge these batteries(POWEREX MH-C808M BATTERY CHARGER AA AAA C D NiMH NiCD), and I have NO PROBLEMS placing the battery in the charger. The advertised capacity is correct and they are indeed very low self discharge.
Sure Eneloop AA are great SANYO eneloop 4 Pack AA NiMH Pre-Charged Rechargeable Batteries(I own quite a few of them and couldn't be happier), but they drain fast if your application requires D batteries and it's a pain to recharge them on a weekly basis.
Previously I used AA Eneloop with their D size adapters, but I started to get annoyed about having to replace/recharge batteries almost every week.
**** Update May 14, 2009 ****
THESE BATTERIES ARE WITH IN SPEC.
I measured my AccuPower D batteries and they are about 59.6 mm. The ANSI spec call for 60.5 mm +/- 1.0 mm (not 61.5 mm). Therefore, the battery should measure between 59.5 mm to 61.5 mm. This makes the battery with in spec!
In fact, these are their specs:

In response to a comment I remeasured these batteries stacked using a Stanley 30' Powerlock measuring tape. I did this because I do not have a caliper and my previous measurement may be off compared to a caliper measurement.
The premise is that if the batteries are too long, then stacking them will make the length problem obvious even to a measuring tape. Here are the results:
1) I staked four cells and measured again as best as I could with my measuring tape and got almost exactly 9.5 inches or 241.3 mm which translates to 60.325 mm per battery.
2) Next I staked eight cells and did the same thing. I got about 19 3/16 inches or 487.3625 mm which translates to about 60.92 mm per battery.
3) Next I staked twelve cells and got about 28 10/16 inches or 727.075 mm which translates to about 60.59 mm per battery.
The measurements were not caliper quality but I got a measurement range between 60.325 to 60.92 inches. This new set of measurements puts Bill King and I about 0.875 to 0.28 apart. Note Bill King, my previous and new measurements are all with in ANSI spec though.

The AccuEvolution ready-to-use rechargeable battery offers the advantages of both alkaline and NiMH cells without their disadvantages. Similar to NiMH rechargeable batteries AccuEvolution can be recharged up to 1000 times. But unlike NiMH batteries they keepmost of their capacity over time.AccuEvolution batteries outperform even top-notch NiMH batteries with higher initial capacity. While conventional rechargeable batteries loose 20% of their capacity every month, AccuEvolution looses only 2% of its capacity every month. After only 1 month the AccuEvolution 2200mAh AA cell offers more useable capacity than a more expensive, conventional NiMH 2700mAh AA battery.Meaning, for instance, that your flashlights will still shine bright even after months of storage.
