2Pack 20V 6.0Ah Lithium Battery Replacement for Craftsman CMCB202 CMCB204 CMCB0206 and CMCB104 Charger Replacement for Craftsman Compatible with V20 Tools

What It Is

This is a 2-pack of 20V 6.0Ah lithium-ion replacement batteries designed for Craftsman V20 cordless lawn mowers, trimmers, blowers, and other V20 tools. It also includes a compatible charger, making it a complete power solution for multi-tool households.

Fitment & Compatibility

• Exact OEM replacements for: Craftsman CMCB202, CMCB204, and CMCB0206 batteries. Also works with CMCB104 charger.
• Tool compatibility: All Craftsman V20 platform tools (lawn mowers, string trimmers, leaf blowers, chainsaws, etc.). Does not fit older 19.2V Craftsman tools.
• Measurements: 5.4 x 3.1 x 2.6 inches per battery. Weight ~1.3 lbs each. Check your tool battery compartment depth—some mowers have tight clearance.
• Important: This is an aftermarket (non-OEM) product. It will not charge on non-Craftsman V20 chargers. Verify your charger model number matches CMCB104 or compatible.

Key Things to Know

• Quality: 6.0Ah capacity is 50% larger than standard 4.0Ah batteries—longer runtime for mowing. Cells are typically grade-A lithium, but lifespan may be shorter than genuine Craftsman (2-3 years vs 3-5).
• Installation: Slide-on, click-in design—no tools needed. Same as OEM. Ensure battery is fully seated before use.
• Common gotcha: The charger included may have a slower charge rate (1.5A vs 2.0A on some OEM chargers). Expect 4-5 hours for a full charge.
• Warranty: Most aftermarket packs offer 1-year warranty (check listing). OEM Craftsman batteries have 2-3 years.

Should You Buy It

Buy this if you need affordable backup power for multiple V20 tools and don’t mind slightly slower charging. It’s a solid value for light-to-medium lawn care (single mowing session per battery). Skip it if you want OEM reliability, fast charging, or maximum lifespan—stick with genuine Craftsman.
