The MH-C9000 Wizard1 Battery Charger & Analyzer. Suitable for the casual consumer users, enthusiast and professionals, the MH-C9000 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 1.5”, the display is more than three times larger than its closest competition and shows a wealth of information that is very easy to read.

In addition to the standard charging, conditioning and discharging, the MH-C9000 Wizard One 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 12 cycles. There are ten selectable charging and discharging currents 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 either “basic” or “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 MH-C9000 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.

Five modes of operation

Charge: Recharges the battery at the selected rate.
-- Suitable for batteries used frequently
Refresh & Analyze: Charges the battery, rest for one hour, discharge, rest again, then recharges it. Selectable charging and discharging rate.
-- Suitable for batteries stored for more than two weeks but less than 3 month or those showing poor performance
Break-In: Also known as IEC capacity measurement and "Battery Forming". Charges battery at 0.1C for 16 hours, rest for one hour, discharges battery at 0.2C, then recharges again at 0.1C for 16 hours.
-- Suitable for new batteries and those stored for more than 3 month.
Discharge: Discharges the battery at the selected rate.
Cycle: Performs charge-discharge cycle for up to 12 times with discharge capacity stored in memory. Recharges battery after final cycle.

New ways to take care of your batteries and maximize runtime!

Battery Matching

-- In most devices, usually two or more batteries are used together. When batteries are used in a series, the performance is limited by the worst one. In other words, one poorly performing battery can significantly reduce the device runtime.

-- Battery matching refers to grouping batteries with similar “actual” capacity. To perform this, use the Refresh & Analyze mode to determine the battery capacity. Group batteries with capacity within about +/- 5% of the rated capacity.

Battery Forming

-- New batteries and those stored for extended period become chemically deactivated. Battery forming is a charge-discharge-charge cycle which forces a full charge into the battery at a very slow rate. This process activates the battery. In certain cases, it needs to be repeated two or three times.

-- Battery forming can be performed using the Break-In mode.

Delivers just the right charge

-- Independent negative delta V, temperature and timer protection eliminates over and undercharging.

Super light travel worldwide power supply and 12V compatible

-- Worldwide 100-240V switching adapter - light weight and small. Also compatible with 12V input. Will work on car when used with the optional cigarette lighter adapter.

Maha MH-C9000 Battery Charger Status Display

Question: Does the MH-C9000 still maintain all the 10 charge rates up to and including the 2000mA charge rate when charging 4 AA batteries. ?

Answer: Absolutely. The MH-C9000 charger can be programmed to charge at any of the 10 programmable charge rates even when charging 4 batteries.

Question: What is the weight of the AC power adapter ?

Answer: The AC power adapter weighs 170gr (6oz.)

Question: Can you use the battery forming feature on older batteries or on New batteries only ?

Answer: You can use the battery forming mode at any time you feel that your batteries may not be performing as they once did. Often you can use the forming mode to help refresh any of your rechargeable batteries and help extend their usefu8l life as well.

Question: Does the MH-C9000 charger have a Trickle Charge ?

Answer: Yes it does. As a matter of fact in certain modes, a "TOP OFF CHARGE" is applied after rapid charge termination to top off the battery. The rate is typically 0.1C ( Approx. 200mA ) and is applied for one hour. After that, an indefinite trickle charge is applied, usually at 0.005C (so around 10mA for AA rechargeable batteries) using modulated pulse trickle charge. This assures good battery performance even if the batteries are left in the charger for an extended period of time.

Question: Does the MH-C9000 battery charger have any limit on rechargeable battery capacity ?

Answer: Answered by: William Chueh of Maha Energy : The micro controller can support higher capacity batteries without any problem (however the capacity calculation limit is 20,000mAh).

Question: Does the MH-C9000 have a Charge/Test that follows the proper IEC standard procedure (rest period of one hour, IEC standard) ?

Answer: Answered by: William Chueh of Maha Energy : The MH-C9000 does have a built-in "IEC" capacity program under the "Break-In" mode.

The sequence is:
1. Charge for 16 hours at 0.1C (user inputs capacity - though for safety reasons, temperature monitoring will be enabled, but no voltage termination).
2. Rest 1 hour.
3. Discharge at 0.2C (up to 1.0A).
4. Rest 1 hour.
5. Repeat step 1 to 4 for four times.
6. Last discharge capacity is saved.
7. Charge - battery ready for use.

Question: Is the MH-C9000 battery charger compatible withe the New Low Discharge batteries such as the Sanyo Eneloop, Uniross Hybrio, Maha Low Discharge Batteries, Nexcell EnergyOn, Accupower Acculoop as well as all other low discharge batteries?

Answer: Absolutely. All low discharge batteries are NiMH rechargeable batteries and can be charged with the MH-C9000 charger

Question: I received the Alltek storage case with my MH-C9000 charger. Are you sure it was made for the MH-C9000.
I am having difficulty in putting the MH-C9000 charger in the bag for storage. Can you help?

Answer: Sure. First however please note that the Alltek CC1 storage case was not made for any specific piece of equipment. It is a universal case that can be used for different chargers and or equipment as a protective or storage case. We have included it as an extra bonus in order to provide you a way to protect your MH-C9000 charger, that no one else offers at this price.

The MH-C9000 can easily be inserted into the case by using the back compartment of the AllTek CC1 case. Simply lay the case on a flat surface with the flap side up. Open up the protective flap and slide the MH-C9000 charger into back compartment with the back side down and then slide the the AC power adapter into the same compartment next to the side of the MH-C9000. You will then be able to close the flap. Naturally you could also store a few batteries in the front compartment if you desire.
