FMA 14.4V D-Type Ni-Cd / Ni-MH Rechargeable Battery for Metabo 31727000 Cordless Screwdriver & Drill
High-capacity 14.4V rechargeable battery pack built with large-format D-type (33600) cells — significantly larger and higher capacity than standard SC cells. Designed as a DIY replacement for Metabo 31727000 cordless screwdrivers and drills. Available in two chemistry options: Ni-Cd 5000mAh and Ni-MH 7500mAh, both in a 12-cell series (12S) configuration.
Key Features
- D-Type (33600) Large-Format Cells: 33mm diameter × 60mm height — much larger capacity than standard SC cells
- High Capacity: 5000mAh (Ni-Cd) or 7500mAh (Ni-MH) for extended runtime
- 14.4V Nominal Voltage: 12 cells in series (12S1P) for stable power output
- Two Chemistry Options: Ni-Cd for deep-discharge tolerance and durability; Ni-MH for higher capacity and lower memory effect
- Metabo 31727000 Compatible: DIY replacement for Metabo 31727000 cordless power tools
- PVC Heat-Shrink Packaging: Protects and insulates the cell assembly
- Brand New Cells: Fresh stock, not refurbished

- Use appropriate wire gauge for the current rating of your tool.
- Insulate all connections with heat-shrink tubing or electrical tape.
- If unsure about installation, consult a qualified battery technician.
Safety Information
Charging: Use only a charger compatible with Ni-Cd or Ni-MH chemistry (as applicable) at the correct voltage (14.4V / 16.8V max). Do not use Li-ion chargers.
Storage: Store in a cool, dry place (0°C–25°C) away from direct sunlight and heat sources. For Ni-MH, store partially discharged. For Ni-Cd, store fully discharged.
Operation: Do not short-circuit, crush, puncture, or disassemble. Avoid exposure to water or moisture.
Temperature: Operating range: 0°C–45°C (charging); -20°C–60°C (discharging).
Disposal: Dispose of according to local regulations for Ni-Cd / Ni-MH batteries. Do not incinerate or dispose of in regular household waste.
Inspection: Inspect before use. Do not use if cells are swollen, leaking, or damaged.
