What Is a 32700 Battery? An In-Depth Guide

Part 1. What Is a 32700 Battery?

A 32700 battery is a large, cylindrical rechargeable cell recognized for its high capacity and consistent performance. The name "32700" reflects its size: 32mm in diameter and 70mm in length.

Key advantages include:

• High Capacity: Stores a substantial amount of energy for long-term use.

• Long Cycle Life: Can be recharged multiple times with minimal capacity loss.

• Stable Voltage Output: Ensures consistent device performance.

• Enhanced Safety: Especially in LiFePO4 variants, offering excellent thermal stability.

Part 2. Dimensions

The 32700 battery measures 32mm in diameter and 70mm in length, making it larger than common cylindrical cells like the 18650 and 21700. This size provides higher capacity but may be bulkier for portable applications.

Part 3. Voltage Range

Voltage varies based on chemistry:

• LiFePO4: 3.2V nominal voltage

• Li-ion: 3.7V nominal voltage

Selecting the correct voltage is crucial for device compatibility and safe operation.

Part 4. Weight Information

32700 batteries weigh between 145g and 160g, depending on chemistry and manufacturer. The added weight supports increased capacity and longer lifespan, important for high-drain applications.

Part 5. Battery Chemistry

Two main chemistries are available:

• Lithium Iron Phosphate (LiFePO4): Safe, long-lasting, and thermally stable.

• Lithium-Ion (Li-ion): Higher energy density with a lighter weight, but requires careful handling.

Part 6. Types of 32700 Batteries

Based on chemistry, Xiaolu Battery offers:

• 32700 LiFePO4 Batteries: 3.2V, high safety, long cycle life.
