Product Specification

NiMH 3.6V C4000mAh Rechargeable Flashlight Battery For Caing Lantern

Features

1. High Capacity for Extended Runtime: The 4000mAh capacity provides long-lasting power for camping lanterns and flashlights, reducing the need for frequent recharges during extended use .

2. Robust Performance in Various Temperatures: NiMH chemistry can perform reliably in a range of conditions, with discharge operating temperatures from -20°C to +60°C . 

3. Long Cycle Life: This battery can withstand over 500 charge-discharge cycles while maintaining more than 80% of its initial capacity, offering good longevity and value .

4. Environmentally Friendly: NiMH batteries are generally considered a "green" choice as they do not contain toxic heavy metals like cadmium or lead .

5. Maintenance and Storage: For long-term storage, it's recommended to store the battery at a partial state of charge (around 40-50%) in a cool, dry place .

Specifications

Applications

• Camping Lanterns and Flashlights: Provides reliable, long-lasting power for outdoor lighting .

• Emergency Lighting: A common application for batteries of this voltage and capacity .

• Other Portable Devices: Various portable electronics requiring a robust power source.

Warnings & Precautions

Charging

• Use a NiMH-Specific Charger: Always use a charger designed for NiMH chemistry and configured for this battery's voltage (3.6V) and current limits. Using an incompatible charger can be dangerous .

• Avoid Overcharging: While NiMH batteries are somewhat tolerant, excessive overcharging can damage them and reduce their lifespan. Use smart chargers with proper termination methods (-ΔV or temperature sensing) .

• Temperature Monitoring: Charge only within the specified temperature range (0°C to +45°C). Charging outside this range can lead to reduced capacity and potential damage .

Discharging

• Avoid Deep Discharge: Avoid discharging the battery below the cut-off voltage (3.0V for the pack, or 1.0V per cell) to prevent irreversible internal damage.

• Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to +60°C). Extreme cold reduces performance; extreme heat accelerates aging .

Storage

• Partial Charge Storage: For long-term storage (longer than a few months), store the battery at a partial state of charge (around 40-50%) .

• Cool and Dry Environment: Store in a cool, dry place away from direct sunlight, moisture, and heat sources .

• Isolation: Store batteries separately in non-conductive containers to prevent short circuits and contact with metal objects .
