Mô tả sản phẩm
Rechargeable Ni-MH D-Cell Battery Pack, 3.6V High Capacity 8000mAh for Long Runtime
Features
-
High Capacity & Long Runtime: The large D-cell format provides an exceptional energy reserve (8.0Ah), enabling extended operation for power-hungry devices.
-
Inherently Safe & Stable Chemistry: Ni-MH chemistry is more resistant to thermal runaway compared to lithium-based batteries and does not require a complex Battery Management System , making it a robust and safe choice.
-
Excellent High-Current Performance: Capable of delivering high continuous and pulse discharge currents, suitable for applications with motor starts or other high inrush loads.
-
Wide Operating Temperature Range: Performs reliably in a broad range of environments, from -20°C to 60°C.

Applications
-
High-Powered Portable Electronics: Professional portable lighting, powerful boomboxes, large portable fans.
-
Toys & Hobbyist Models: High-performance radio-controlled (RC) vehicles (cars, boats), large-scale model robotics.
-
Emergency & Backup Systems: Emergency lighting units, backup power for security/alarm panels.
-
Professional Tools: Certain cordless tools where safety and durability are prioritized over extreme energy density.
Warnings & Precautions
Charging
-
Use a Ni-MH Specific Charger: Always use a smart charger designed for Ni-MH chemistry that features -ΔV (negative delta voltage) detection and temperature monitoring to correctly terminate the charge. Never use a Ni-Cd (nickel-cadmium) only charger.
-
Avoid Continuous Trickle Charging: Modern high-capacity Ni-MH cells are not designed for indefinite trickle charging. This can lead to overcharge and damage. If a maintenance charge is needed, use a very low current (< C/50) and a timer.
-
Charge in a Safe Area: Charge in a well-ventilated area on a non-flammable surface.
Discharging
-
Prevent Deep Discharge: Never discharge the pack below 3.0V under load. Allowing individual cells to reverse polarity can cause permanent damage.
-
Current Limits: Adhere to the maximum continuous discharge rating. While the pack can handle high pulses, sustained over-current will cause excessive heat and shorten lifespan.
-
Allow Cooling: Let the battery cool to near ambient temperature after heavy use before recharging.
-
Optimal Storage State: For long-term storage (>1 month), condition the pack to a 40-60% state of charge (open-circuit voltage ~3.8V - 3.9V).
-
Cell Matching: When building or servicing the pack, ensure all cells are from the same manufacturer, model, and batch to ensure balanced performance.
-
Care: Do not puncture, crush, or disassemble the pack. Keep terminals clean and protected from short circuits.
