Li-FeS2 Batteries
This page is reorganized for faster outdoor and portable-device procurement review. Instead of placing “Outdoor” inside a table structure, the page now highlights application fit first, then compares AA and AAA formats, and finally summarizes usage benefits and safety precautions more clearly.
Application Focus
Suitable for outdoor devices, flashlights, remote controls, portable equipment, and other applications where lightweight design and low-temperature performance matter.
Core Chemistry Direction
Li-FeS2 is a 1.5V primary lithium battery direction often selected for lighter weight, cold-weather use, and better portability than standard alkaline options.
Key Advantages
Lightweight design, deep-freeze resistance, strong outdoor usability, and practical continuous-discharge support for portable electronics and lighting devices.
Commercial Fit
More suitable for buyers sourcing outdoor-oriented AA / AAA battery programs where cold-weather use and lighter battery weight are part of the value proposition.
AA FR6 Li-FeS2 Battery
A lightweight 1.5V lithium AA model for outdoor and portable applications where low-temperature resistance and long usable discharge time are important.
Item No.: AA FR6
Chemistry: Li-FeS2
- Operates normally at approximately -40°C to 60°C
- No burst or leakage under stated cold-use conditions
- Remote control / 210 lm flashlight: 5.8 h

Item No.: LFBAAA
Chemistry: Li-FeS2
- Suitable for compact portable devices
- Useful where smaller size and lighter weight both matter
- Lithium iron disulfide battery direction
Suitable for buyers who need an outdoor-capable or portable-oriented AAA lithium option for smaller electronics and field-use accessories.
- Compact and lightweight
- Useful for emergency and travel-oriented device programs
Specification Summary by Size
For buyers who want a faster way to compare the AA and AAA Li-FeS2 options, the following grouped table summarizes the key size and performance differences.
AA Models
Suitable for outdoor equipment, flashlights, and portable products where longer discharge support and stronger power reserve are more important than ultra-compact size.
| Item No. | Voltage | Capacity | Weight | Dimensions |
|---|---|---|---|---|
| AA FR6 | 1.5V | 2500mAh | Approx. 15g | 14.0 ±0.5 mm × 49.85 ±0.65 mm |
| LFBAA | 1.5V | 2900mAh | Approx. 15g | 14.0 ±0.5 mm × 49.85 ±0.65 mm |
AAA Model
Suitable for smaller portable electronics and applications where compact size and light battery weight are more important than maximum capacity.
| Item No. | Voltage | Capacity | Weight | Dimensions |
|---|---|---|---|---|
| LFBAAA | 1.5V | 1200mAh | Approx. 7.5g | 10.0 ±0.5 mm × 44.0 ±0.5 mm |
Outdoor Use Advantages and Precautions
Lightweight Design: AA models are approximately 15 g and the AAA model is approximately 7.5 g, helping reduce battery weight in portable and outdoor-use equipment.
Cold-Weather Direction: The AA outdoor models are positioned for operation at approximately -40°C to 60°C, making them more suitable for deep-freeze and outdoor-use scenarios than standard household battery programs.
Application Value: This chemistry direction is more suitable for flashlights, outdoor electronics, emergency-use gear, and portable products where lighter weight and stronger cold tolerance matter.
Precautions: Keep away from fire, impact, and serious physical damage. Do not recharge, short-circuit, puncture, disassemble, crush, or heat above 212°F (100°C). Dispose of used batteries properly and promptly.
