The WizardOne Battery Charger-Analyzer is suitable for casual consumers, enthusiasts 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. Features a large LCD screen, backlit by ultra-bright white LEDs. Measuring over 3.5" x 1.5", the display is more than three times larger than its closest competition and shows a wealth of information that is easy to read.

There are 10 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 a basic and advanced mode. In the basic mode, the user merely needs to insert the batteries with no further key press. The charger will select the appropriate settings automatically.

Five modes of operation: 

• Charge: Recharges the battery at the selected rate. Suitable for batteries used frequently.
• Refresh and Analyze: Charges the battery, rests for one hour, discharges, rests again, then recharges it. Selectable charging and discharging rate. Suitable for batteries stored for more than two weeks but less than three months or those showing poor performance.
• Break-In: Also known as IEC capacity measurement and "Battery Forming." Charges battery at 0.1C for 16 hours, rests 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 three months.
• 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.
