Many customers ask “How do the new IMEDION AA rechargeable batteries compare to the eneloop AA rechargeable batteries?
Both are a low discharge technology, so they retain up to 85% of their charge after 12 months. But the eneloops have been available for a while, whereas the IMEDIONs are new. Has Maha been able to develop a better performer?
It would seem so. Test results have demonstrated IMEDION AA batteries outperforming the eneloop AA batteries in capacity measurements and discharge tests. Anders over on the Candle Power Forum has done many tests on the IMEDION AA batteries. The results of one of the tests, a comparison to the eneloop batteries, is shown below.
Update: Anders has noted that the eneloop graph is not correct. To see a more comparable graph, see the eneloop tests by Silverfox.
Here in Australia, several people have done their own tests and published the results on the whirlpool forum. Results by “Horrorking” can be seen here and IMEDION and eneloop performance tests in a Nikon SB-800 camera flash can be seen here
While the IMEDION AA batteries demonstrate a capacity advantage over the eneloop batteries, the other benefit of the IMEDION batteries is that they include a free AA battery holder, whereas the eneloop batteries do not.
EDIT: Fixed typo’s and added link to eneloop test results – sorry for misspelling your name Anders!

Powerex IMEDION Batteries – “Ready When You Are”
City of Industry, CA – Oct 25, 2007 — Maha Energy, the maker of Powerex batteries and chargers, is pleased to introduce a new line of rechargeable batteries: IMEDION. Unlike traditional NiMH batteries, IMEDION can be stored for an extended period of time without substantial loss of power and are ready to use out-of-package. As the name suggests, the IMEDION batteries will be “ready immediately!â€
A common problem that plagues rechargeable batteries is that they need to be recharged about once every three months even if they are not used. Maha tackled this issue by developing advanced electrode materials to reduce the rate of power loss during storage. As a result, the IMEDION batteries retain up to 85% of its charge even after one year of storage (at a room temperature of 20 deg C).
The IMEDION batteries differ from the competition in that they boast a longer lifetime as well as increased power retention under warmer environments. The IMEDION batteries can be recharged for hundreds of times and perform extraordinarily well at elevated temperatures. In addition, the IMEDIONs feature a low-impedance design and can deliver a high burst of current.
The IMEDION AA batteries and IMEDION AAA batteries are fully compatible with all Powerex chargers and are available in 2100mAh capacity for AA size and 800mAh for AAA.
EDIT: Stock will be available in Australia from October 31. Stock is available now.

Maha Announces a Battery Charger-Analyzer from the Future!
La Verne, California, USA – 7th November, 2006 — Maha Energy, the maker of Powerex batteries and chargers, is pleased to announce its most significant product in five years: MH-C9000 WizardOne Battery Charger & Analyzer. Suitable for the casual consumer users, enthusiast and professionals, WizardOne is capable of charging, conditioning, analyzing, cycling, forming and discharging one to four AA or AAA batteries, all while digitally displaying the battery capacity and voltage. All four slots can be operated independently in different modes and settings. A total of five modes are available.
Those seeing the unit for the first time will be struck by its large LCD screen, backlit by ultra-bright white LEDs. Measuring over 3.5†by 1.5â€, the display is more than three times larger than its closest competition and shows a wealth of information that is easy to read.
In addition to the standard charging, conditioning and discharging, the WizardOne charger-analyzer also offers two unusual operations modes. The “Break-In†mode allows the user to input the capacity of the battery and performs a “forming†charge designed to properly break-in new batteries. The “Cycle†mode allows user to charge and discharge batteries consecutively while storing the capacity for up to 15 cycles. There are ten selectable charging and discharging current from 0.2A to 2.0A and 0.1A to 1.0A respectively. The charger also features four independent temperature sensors using Maha’s latest temperature rise detection algorithm in addition to the usual peak temperature detection. It also armed with additional patented termination algorithms found in other Maha chargers.
The unit can be operated in a “basic†and “advanced†mode. In the basic mode, user merely needs to insert the batteries with no further key press. The charger will select the appropriate settings automatically, making it suitable for the casual users.
The WizardOne is also incredibly accurate. Using a quartz oscillator time base typically found in computer boards, it is able to report capacity within 1% accuracy across multiple units making battery bench marking more meaningful.
MH-C9000 is expected to be available in Australia from January 2007 with a price of $99.95. The standard package will include a worldwide travel power supply. A 12V car adapter will be available as an option.

 Nikon has announced the latest addition to their DSLR range with the D80. With a 10.2 Megapixel sensor and a great kit lens, this looks like it will become a popular choice among digital camera enthusiasts.
An option to extend the battery life of the Nikon D80 is the MB-D80 Battery Pack/Vertical grip as shown in the photos. This will hold two of the Nikon EN-EL3e batteries, or six AA batteries.
The EN-EL3e is the same battery as used in the D200. Note that the EN-EL3 (as used in the D70) cannot be used in the Nikon D80 or D200.
 The En-EL3e battery provides 1500 mAh at 7.4 V (11.1 Wh), so a pair would provide 3000mAh at 7.4V.
Maha PowerEx AA batteries are compatible with the Nikon MB-D80. Six of our 2700mAh AA batteries would provide 2700mAH at 7.2V, and thus provide a nearly the same amount of battery power, but cost substantially less than one EN-EL3e battery.
It is reported that a single D80 battery will provide 2,700 shots, so the battery pack with 6x 2700mAh AA batteries should provide the camera with enough power to take around 4,860 photos off a single set of batteries, whether they are EN-EL3e or rechargeable AA’s.
