Quick answer

For high-volume charging with fast Turbo mode, choose the 8-slot Powerex MH-C980. For dedicated battery analysis and conditioning, choose the 4-slot Powerex MH-C9000PRO.

Slot count and charging volume

The MH-C980 holds eight batteries, while the MH-C9000PRO holds four. This directly affects how many batteries you can charge at once.

The MH-C980 uses independent charging circuits for each slot, letting you mix AA and AAA batteries in any combination without issue. This makes it ideal for photographers or enthusiasts who cycle through many cells in a day.

The MH-C9000PRO's four slots are also independent, so you can charge AA and AAA together. If you only need to charge a few batteries at a time, the smaller footprint saves desk space.

Charging speed and analysis features

Speed is a major trade-off. The MH-C980 defaults to a two-hour charge for AA cells and can switch to Turbo mode for a one-hour charge. That's a significant time saving when you need batteries ready quickly.

The MH-C9000PRO does not specify a Turbo mode. Instead, it offers four operation modes: Charge, Break-In, Discharge, and Refresh & Analyze. If your priority is analyzing battery health, restoring old cells, or conditioning new ones, the C9000PRO's mode selection is far more versatile.

Both models display capacity and voltage on large backlit LCD screens, but the C9000PRO adds time and rate information, which advanced users may want for tracking charging progress.

Trade-offs at a glance

  • Number of charging slots: MH-C980: 8 slots; MH-C9000PRO: 4 slots. More slots means higher throughput for large battery collections.
  • Turbo mode (fast charge): MH-C980 offers Turbo mode for 1-hour AA charging; MH-C9000PRO does not have a Turbo mode. Choose the C980 if speed is critical; the C9000PRO prioritizes analysis over speed.
  • Analysis and conditioning modes: MH-C9000PRO offers Charge, Break-In, Discharge, Refresh & Analyze; MH-C980 has a one-touch battery health analysis that displays capacity. The C9000PRO gives you more control over battery maintenance procedures.
