Maha MH-C9000 NiMH charger
  • 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.
  • Has a large LCD screen, backlit by bright white LEDs.

$95

$116 (with 4 Maha AA 2700 batteries)

Settings

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.
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.

Summary

  • Charge, condition and analyze one to four AA or AAA batteries. Independent operation of each slot.
  • Large backlit LCD.
  • Digitally displays capacity, voltage, time elapsed and current.
  • Adjustable charging rate from 0.2 to 2.0A and discharging rate from 0.1A to 1.0A.

      Five modes of operation:
    1. -- Charge: Charge the battery at the selected rate
    2. -- Discharge: Discharge the battery at the selected rate.
    3. -- Analyze & Refresh: First charge the battery at the selected rate, then discharge it at the selected rate followed by recharging. The discharge capacity is saved for display at the end of the cycle.
    4. -- Break-In: Allows user to enter the battery capacity and performs a forming charge at 0.1C for 16 hours (using only temperature and timer cutoff) followed by discharge and medium rate recharge.
    5. -- Cycle: Allows user to set charge and discharge rate and number of cycle to perform. Will save capacity up to 12 cycles which user can access throughout the cycling.

  • Negative delta V, peak voltage, dT/dt (temperature rise) and max Temperature protection
  • Four independent thermocouples to manage battery temperature.
  • Quartz-oscillator time base for 1% repeatability in capacity calculations.
  • Trickle Charge - Around 10mA trickle charge rate when charging AA rechargable batteries.
  • 12V input and can be powered by an optional car adapter
  • Worldwide switching power supply.
  • Rugged construction with extensive ventilation for the batteries.
  • Built-in “lift rod” to raise the charger to improve air flow below the unit
