Confused about choosing between 4Ah and 6Ah batteries for your power tools? This guide breaks down their differences, applications, and industry trends to help professionals and DIY enthusiasts make informed decisions.

Understanding Amp-Hour Ratings: The Basics

Let''s start with the fundamentals: 4Ah (4 amp-hour) and 6Ah (6 amp-hour) batteries differ primarily in energy capacity. Think of amp-hours as the "fuel tank" of your power tools – a 6Ah battery simply holds 50% more energy than a 4Ah model. But there''s more to the story than just numbers.

Key Differences at a Glance

• Runtime: A 6Ah battery lasts 1.5x longer than a 4Ah under similar loads
• Weight: 6Ah models are typically 20-30% heavier
• Cost: 6Ah batteries cost 35-50% more on average

Industry Applications: Where Each Battery Shines

Different jobs demand different power solutions. Here''s how professionals across industries use these batteries:

Construction & Contracting

6Ah batteries dominate heavy-duty tasks like:

• Continuous concrete drilling
• All-day framing nail gun operation
• High-torque impact wrench use

DIY & Home Maintenance

4Ah batteries are ideal for:

• Weekend furniture assembly
• Light garden trimming
• Occasional drill/driver use
