More information

Taken From MAHA's site:

Four independent slots
 

It's like having four charger-analyzers for AA and AAA NiMH / NiCD batteries.

 
Large backlit LCD display

Digitally displays capacity, voltage, time and current.
 
Endless programming possibilities - over 10,000 ways!
 

29 selectable charging and discharging rate. Charging current from 0.2A to 2.0A and discharging current from 0.1A to 1.0A in 0.1A increments.
 
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

This is not a charger this is a semi-professional (or professional) reconditioning charger. If you are an average home user, with a few batteries to charge I would not suggest this charger as it is not a drop and go kind of charger. This charger is intended for people who have a large amount of batteries and good knowledge of how to recharge them properly. With the safeties it would be hard to cause real damage, but you can certainly lower the cycle rate (how many times you can recharge the batteries).

One thing left out of MAHA's advertisement is the ability of this charger to sense and properly charge the new low loss batteries. New batteries such as: Imedion, Eneloop, EnergyOn, Accupower, Acculoop, and Hybrio are all properly charged by this charger. Not many chargers will work properly with these new low loss batteries.
FYI: Low discharge batteries only loose 15% of their power when stored for a year, older battery types loose 75% or more in the same time. Beware that some cheaper Low Discharge batteries can only be recharged about 500 times.

Overall this conditioning charger is the Rolls Royce of chargers.
