Lithium batteries have revolutionized the power tool industry, offering higher energy density, longer lifespan, and faster charging compared to traditional alternatives. But what specific types of lithium batteries are used in tool batteries? This guide explores the technology behind cordless tools, industry trends, and how to choose the best battery for your needs.

Types of Lithium Batteries in Power Tools

Not all lithium batteries are the same. Here are the most common types used in modern tool batteries:

• Lithium Cobalt Oxide (LiCoO₂): Known for high energy density but limited thermal stability.
• Lithium Manganese Oxide (LiMn₂O₄): Balances safety and performance, often used in mid-range tools.
• Nickel Manganese Cobalt (NMC): Combines high capacity with thermal resilience, dominating premium tools.
• Lithium Iron Phosphate (LiFePO₄): Prioritizes safety and longevity, ideal for heavy-duty applications.

Why NMC Batteries Dominate the Market

Over 68% of professional-grade cordless tools now use NMC lithium batteries due to their:

• Energy density: 150–200 Wh/kg
• Cycle life: 1,000–2,000 charges
• Fast charging: 80% capacity in 30 minutes

Battery Type	Voltage Range	Cycle Life	Common Applications
LiCoO₂	3.6V	500–800	Light-duty drills
LiMn₂O₄	3.7V	800–1,200	Angle grinders
NMC	3.6–3.7V	1,000–2,000	Impact drivers, saws
LiFePO₄	3.2V	2,000–5,000	Industrial tools

Key Factors When Choosing Tool Batteries

Selecting the right lithium battery involves three critical considerations:

1. Voltage Compatibility: Match the battery voltage (18V, 20V, 40V) to your tool''s requirements.
2. Capacity (Ah): Higher amp-hours mean longer runtime but increase weight.
3. Temperature Tolerance: LiFePO₄ operates reliably in -20°C to 60°C environments.
