Highest capacity low-self-discharge batteries with an improved rapid charger,
This review is from: Sanyo XX Battery Powered by eneloop, 2500mAh (MIN 2400) High Capacity, 4 Pack AA Ni-MH Pre-Charged With MQRO6 quick charger (Accessory)
This package (Sanyo XX Battery Powered by eneloop, 2500mAh High Capacity, 4 Pack AA Ni-MH Pre-Charged With MQRO6 quick charger) is a great combo - for people who really need that extra power.
The SANYO eneloop XX cell is currently the highest capacity LSD (low-self-discharge, or "Pre-Charge") AA battery. Sanyo rated the capacity as "2500mAh typ., 2400mAh min.". The measured average capacity, using my La Crosse BC-900 battery charger/analyzer, is even better at 2607mAh, or 4% higher than spec.
Just for comparison, here are some of my test results for other LSD cells:
- SANYO New (1500-cycle) eneloop AA: Rated 2000mAh, tested ~2100mAh (5% higher).
- GP Recyko NiMH AA: Rated 2100mAh, tested ~2230mAh (6% higher).
- IMEDION AA: Rated 2400mAh, tested ~2450mAh (2% higher).
- Yuasa Enitime PLUS AA: Rated 2500mAh, tested ~2400mAh (4% LOWER)
The self-discharge rate of Sanyo XX cell is slightly higher than that of Sanyo eneloop. According to my test, the XX retained ~78% of measured capacity after five months of storage, whereas eneloop can typically retain ~88%. For all practical purposes, the charge-retention rate of XX is good enough.
The charger in this package is the new MQR06, which is not to be confused with the old MQN06 sold with most eneloop packages. Just to help you remember: R=Rapid and N=Normal/slow.
- The old MQN06 is very slow and it charges in pairs (2 or 4 cells) only.
- The new MQR06 charges much faster, handles odd number of cells, and has individual status lights.
The charging current of MQR06 depends on the number of cells being charged:
- For 3-4 AA cells, the charging current is 560mA. So it takes about 5 hours to fully recharge a set of 2500mAh Sanyo XX cells
- For 2 cells, the charging current doubles to 1120mA, then it only take 2.5 hours to recharge a pair of Sanyo XX cells.
- For 1 cell, the charging current increases to 1680mA. By the way, it is actually not a good idea to charge at such a fast rate.
In contrast, the old MQN06 charges 2 or 4 cells at 300mA, so it takes about 9 hours to recharge those Sanyo XX cells.
The only drawback of this package is higher price. As of this writing, you can get the Sony Cycle Energy BCG34HRE4KN Quick with Refresh Charger and 4 Pre-Charged 2000 mAh AA Batteries plus an extra set of eneloop cells for the same cost. The Sony charge is very similar to the MQR06 in terms of charging current, but it added a REFRESH function.
Bottom line: If you really need the extra 25% capacity of Sanyo XX for mission-critical application, then this Sanyo package is your best choice. Otherwise, consider getting the Sony package with an extra set of eneloop cells instead.

I've read most of your comments, but none have referred to cameras that use an external flash. I plan to purchase a Canon Speedlite EX430. I understand this flash uses a lot of juice to quickly recycle between flashes. Do you recommend one version of eneloop over another?
Thank you kindly!

I have been using rechargeable AA cells in my old Speedlite 420EX. To me, the battery brand does not matter as long as they are LSD type. However, other people swear by eneloop as the best in terms of flash recycle time. See this thread:
I expect you to see very little difference in recycle time between using Sanyo XX and eneloop cells. The main difference in that the XX can delieve ~25% more flashes per charge.

can you recharge AAA with this charger?

NLee the Engineer says:
Yes you can recharge AAA cells with the MQR06. The charging current is half that for AA cells.

Good Review, but I don't think most of us need so fast a charge and some of the chargers listed are almost double in price which is ok if u take a lot of pix, otherwise a 9 dollar charger is find and i dont like leaving fully charged batteries in a charger for days ( i seen lithiums destroyed in a few moths of constant charging..my $200 logitech keyboard is one example..charger says 500 milliamps, sounds way too high if left on for days on end.. maybe their shut off circuit isn't designed properly because they've had thousands of these units dumped on ebay for sale..Oh, and i might add, ebay don't want you to know they just want the money.

Lithiums have even more "calendar limited" service lives and fussier charging requirements than NiMH. Properly maintained, top quality NiCd is the most long-lived of the three types. Specialized NiCds also love high current discharge and reasonably fast charging. They just have bad rep 'cause most users haven't maintained them properly, which requires [among other things] individual cells having monthly full discharge.
I wish Duracell would bring back to market the CEF12 and CEF23 chargers. They're tops for individual NiMH cell smart chargers. We have several of each, been using them for years, and all still work flawlessly.
