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.

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 FR61.5V2500mAhApprox. 15g14.0 ±0.5 mm × 49.85 ±0.65 mm
LFBAA1.5V2900mAhApprox. 15g14.0 ±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

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.
