Replacement Battery for Craftsman 20V V20 CMCB204 CMCB202 - 2-Pack

In this review of the Replacement Battery for Craftsman 20V V20 CMCB204 CMCB202, the bottom line is simple: this two-pack delivers reliable, higher-capacity runtime for owners of Craftsman 20V MAX tools who need an affordable OEM-compatible spare. The reviewer found it particularly useful for yard work and extended projects because the 6000mAh cells offer noticeably longer runtime than many older packs, and the batteries fit original Craftsman 20V chargers without modification. It is a good choice for users who want more runtime at a lower price than factory-branded batteries.

Key Features

• Actual 6000mAh capacity: Provides longer runtime for extended tasks, helping finish more work between charges.
• 20V lithium-ion cells: Matches the voltage of Craftsman V20 tools so performance stays consistent with original batteries.
• Charger compatibility: Works with all original Craftsman 20V lithium-ion chargers, so there is no need to buy a new charger.
• LED charge indicators: Three LEDs let users check remaining battery power at a glance and plan work sessions.
• Built-in circuit protection: Protects the pack and tool from overcharge and short conditions for safer use and storage.
• Two-pack value: Includes two 6.0Ah replacement batteries and a user manual, offering a ready spare without repeated single-pack purchases.

Who It's For

This battery pack is aimed at Craftsman 20V tool owners who need extra runtime for yard work, trimming, drilling, or other maintenance projects and prefer an affordable, high-capacity replacement. Builders, homeowners, and weekend DIYers who already have Craftsman chargers will appreciate the straightforward compatibility and the convenience of a two-pack.

It is not suitable for those who use Craftsman 20V max Bolt-On or DieHard series tools, since the pack does not fit those specific models. If the longest possible factory-backed battery life or brand-specific warranty coverage is required, buyers may prefer an original manufacturer pack instead.

Pros & Cons

Pros

• Higher 6000mAh capacity gives extended runtime compared with many stock batteries.

• Three LED indicators and circuit protection add usability and safety.

Cons

• Some users report actual run times of only 2-3 hours under certain loads, so real-world life may vary by tool and task.
