Powerex MH-C980 Turbo Charger-Analyzer

Powerex MH-C980 Turbo Charger-Analyzer

The MH-C980 is an eight-bay NiMH charger-analyzer for AA and AAA cells. Each slot is independently controlled, so you can mix cell sizes, brands, and states of charge while viewing per-cell status and mAh added. Select a fast turbo profile for quick turnarounds or a gentler current to reduce heat and extend battery life.

Highlights

• Eight independent slots: Charge any mix of AA/AAA NiMH cells with per-slot termination.
• Turbo and gentle modes: Choose speed when time is tight, or lower heat for routine charging.
• Per-cell analytics: LCD shows status and mAh added to spot weak or aging cells.
• Conditioning/refresh: Periodic cycles can help rebalance cells for more consistent sets.
• Safety controls: Temperature and voltage monitoring help protect cells and the charger.

Who It’s For

• Event photo/video and live sound: Rapid cycling of multiple AA/AAA sets for flashes, mics, and lights.
• Studios, classrooms, and makerspaces: High-volume charging with visibility into cell health.
• Households: One charger to manage controllers, toys, remotes, and cameras.

Charge-Time Examples

Actual time varies with capacity, starting state of charge, and ambient temperature. Typical ranges from empty:

• AA 2000–2500 mAh: Turbo about 1.5–2.5 hours; gentle about 3–6 hours.
• AAA 800–1000 mAh: Turbo about 0.8–1.5 hours; gentle about 2–3 hours.

Tip: Use turbo when you need cells quickly; use gentler current for everyday cycles to minimize heat.

Independent Slots = Better Results

Each bay measures and terminates individually. You can insert a half-used AA next to a fully depleted AAA without affecting accuracy. Per-slot mAh helps you group batteries into matched sets and retire weak cells before they cause issues in multi-cell devices.

Compatibility and Limits

• Supported: NiMH AA and AAA rechargeable cells, including low self-discharge types.
• Not supported: Alkaline, NiCd, Li-ion, LiFePO4, or any primary (non-rechargeable) batteries.
• Do not attempt to charge damaged, leaking, or swollen cells.

How to Use

1. Place the charger on a hard, ventilated surface; keep vents clear.
2. Connect power and select your charge current (turbo for speed, gentler for longevity).
3. Insert AA/AAA cells in any combination; the charger detects and manages each slot independently.
4. Monitor the LCD for per-slot status and mAh. Remove completed cells and allow them to cool before use.

When to Choose MH-C980

• Choose it if you need eight independent bays, fast turnaround, and diagnostics for set management.
• Consider a simpler 2–4 bay travel charger if you rarely charge more than a few cells at once.
• If you require USB-powered charging only, look for a compact USB model instead.

Care and Maintenance

• Ventilation: Faster charging yields more heat; leave space around the unit.
• Routine cycles: Prefer lower current for everyday charging; reserve turbo for deadlines.
• Set management: Label batteries in sets (A, B, C). Track mAh; retire sets that consistently lag.
• Storage: Keep charged NiMH cells in a cool, dry place. Avoid hot cars and direct sun.

Pros and Cons

• Pros: Eight independent slots, fast or gentle charging, per-cell analytics, maintenance modes.
• Cons: Larger footprint than compact travel units; fast charging can generate noticeable heat.

Troubleshooting

• Cell not recognized: Wipe contacts, rotate the cell, or try another slot to rule out debris.
• Excess heat: Switch to a lower current and improve airflow; avoid stacking chargers closely.
• Uneven mAh readings: Normal across mixed-age cells; use readings to identify weak batteries.
