Using regular rechargeable batteries, such as NiMH or NiCd, in heated clothing is generally not advisable. Here’s why:

1. Battery Type Compatibility

• Designed Batteries: Heated clothing is typically designed to use lithium-ion batteries, which are chosen for their high energy density, lightweight nature, and ability to provide consistent power needed for heating elements.
• Voltage and Capacity: Regular rechargeable batteries may not meet the voltage or capacity requirements for effective heating, leading to subpar performance.

2. Charging Circuit Issues

• Optimized for Lithium-Ion: The charging circuits in heated clothing are usually optimized for lithium-ion batteries, which include built-in protection against overcharging and overheating.
• Potential Damage: Using other types of rechargeable batteries may result in improper charging, potentially damaging both the batteries and the clothing.

3. Performance and Safety

• Power Output: Regular rechargeable batteries might not deliver the necessary power output for heating elements, resulting in insufficient heating.
• Safety Risks: Incompatible batteries can pose safety risks, such as overheating or battery failure, due to differences in battery management and safety features.

4. Manufacturer Recommendations

• Follow Guidelines: It is crucial to adhere to the manufacturer’s guidelines for battery use. Using the recommended lithium-ion batteries ensures compatibility and maintains the warranty and performance of the heated clothing.

Summary

For optimal performance and safety, use the specific lithium-ion batteries recommended by the manufacturer of your heated clothing. These batteries are designed to work effectively with the garment’s heating system, ensuring proper function and longevity.
