20v 6.0Ah Battery Replacement for Craftsman 20v Battery, Compatible with Craftsman V20 Series Cordless Tool and Charger（2pack）

What It Is

This is a 20V 6.0Ah lithium-ion battery replacement pack (two batteries) designed for Craftsman V20 cordless lawn mowers, trimmers, blowers, and other tools in the V20 lineup. It provides higher runtime than the standard 4.0Ah or 2.0Ah packs, making it suitable for larger yards or longer jobs.

Fitment & Compatibility

• Brand & Series: Compatible with Craftsman V20 cordless tools and chargers only. Not for older Craftsman 19.2V or 20V Max systems (those use different battery shapes/voltages).
• Physical Check: Measure your existing battery’s dimensions and terminal layout. This pack is slightly taller than some OEM 2.0Ah batteries, so verify it fits under your mower’s battery compartment cover and doesn’t block the blade or discharge chute.
• Charger Compatibility: Works with Craftsman V20 chargers (model numbers ending in CMCB115, CMCB210, etc.). Does not fit DeWalt, Ryobi, or other brand chargers.
• Tool List: Fits all Craftsman V20 mowers (e.g., CMXGMAM112, CMEMW200), trimmers (CMEST935), blowers (CMEBC703), and hedge trimmers. Check your tool’s user manual for “V20” logo.

Key Things to Know

• Quality & Safety: This is an aftermarket battery, not OEM Craftsman. It uses generic cells. Some users report slightly shorter lifespan than genuine Craftsman batteries, but the 6.0Ah capacity gives 50% more runtime than a 4.0Ah pack.
• Installation Difficulty: None. Slide the battery into your tool until it clicks. No tools or modifications required.
• Common Gotcha: The battery may be slightly thicker than OEM, so it may feel tight in some mower compartments. If your mower has a rigid battery cover, test fitment before fully committing.
• Warranty: Typically 1-year limited vs. Craftsman’s 3-year warranty. Check seller’s return policy for dead-on-arrival issues.

Should You Buy It

Buy this if you need extra runtime for a large lawn (over ¼ acre) and want to save money over two OEM Craftsman 6.0Ah packs (which cost ~$50 each). Skip it if you prioritize long-term reliability, need a perfect fit in a tight mower battery bay, or want the official warranty. For most casual users, the price-to-performance ratio is solid.
