The Powerex MH-C9000PRO Professional Charger-Analyzer is a versatile device designed for charging, analyzing, and maintaining NiMH and NiCD batteries. It features four independent slots, accommodating both AA and AAA size batteries, and offers a range of operational modes to optimize battery performance and lifespan.
The MH-C9000PRO serves as both a charger and an analyzer. Its primary function is to safely charge NiMH and NiCD batteries at user-selectable rates. Beyond simple charging, it provides advanced analysis capabilities to determine battery health, actual capacity, and to recondition batteries that have degraded over time or been stored for extended periods. The device's intelligent design includes safety features such as polarity detection and an impedance check to prevent damage to batteries and the unit itself. It also incorporates a top-off and maintenance charging system to ensure batteries are fully charged and ready for use without overcharging.
The MH-C9000PRO offers four distinct modes of operation:
Charge Mode: This is the standard mode for adding energy to batteries. Users can select a charge rate between 0.2A and 2.0A in 0.1A increments. The charger displays the accumulated energy put into the battery. It's recommended for batteries in good condition that need recharging.
Break-In Mode (IEC Capacity Analysis): This mode is designed to activate new batteries or those that have been stored for an extended period (longer than 6 months). It performs a specific charge-discharge-charge cycle: a 16-hour 0.1C charge, followed by a 1-hour rest, then a 0.2C discharge, another 1-hour rest, and finally a 16-hour 0.1C recharge. This process, also known as "Battery Forming," helps to restore the battery's chemical activity and determine its true capacity according to IEC standards. This mode typically takes 39 to 45 hours to complete and is recommended for batteries that cannot be rescued by the Refresh & Analyze mode.
Discharge Mode: This mode removes all energy from batteries at a user-selected rate between 0.1A and 1.0A in 0.1A increments. It's useful for analyzing the amount of charge stored in a battery or for completely discharging batteries before storage or reconditioning. The charger displays the accumulated energy removed from the battery.
Refresh & Analyze Mode: This comprehensive mode conditions and analyzes batteries at selected charge and discharge rates. It first charges the battery, then rests for an hour, discharges it, rests again for an hour, and finally charges it until fully charged. At the end of the cycle, it reports the "Available Capacity," which is the actual capacity the battery can hold. This mode is ideal for determining the actual capacity of a battery, grouping batteries with similar capacities ("Battery Matching"), and improving the performance of batteries with degraded performance.
The device features an intuitive user interface with a large, backlit LCD display that shows Capacity, Voltage, Time, and Rate. Users can navigate through modes and settings using UP, DOWN, SLOT, and ENTER buttons. A convenient "Easy Setup" feature allows users to set settings for one slot and then apply the same settings to all other slots by pressing and holding the ENTER button. The charger also remembers the last used settings (mode and value) to streamline future operations.
The manual provides guidance on choosing appropriate charge and discharge rates, recommending rates below 30% and above 100% of battery capacity to avoid issues. Slower rates generally yield better performance but take longer, while faster rates may not charge as fully and can increase battery temperature.
For devices using multiple batteries in series, the MH-C9000PRO facilitates "Battery Matching." By using the Refresh & Analyze mode to determine the actual capacity of each battery, users can group batteries with capacities within +/- 5% of their rated capacity. This ensures optimal performance, as the weakest battery often limits the overall performance of a series-connected pack.
The device supports "Battery Forming" through its Break-In mode. This process is crucial for new batteries or those stored for extended periods, as they can become chemically deactivated. The charge-discharge-charge cycle in Break-In mode forces a full charge at a very slow rate, activating the battery. For some batteries, repeating this process two or three times may be necessary.
The MH-C9000PRO includes several features to ensure safe and effective battery maintenance:
The MH-C9000PRO is a comprehensive tool for anyone looking to maximize the performance and lifespan of their NiMH and NiCD batteries through intelligent charging, analysis, and reconditioning.
