TenHutt 20V 6.0Ah Replacement Battery for Craftsman V20 - Longer

In this review the TenHutt 2Pack 20V 6.0Ah replacement batteries are evaluated for users of Craftsman V20 cordless tools seeking extended runtime and reliable power. The bottom line: these batteries are aimed at homeowners and tradespeople who need a higher capacity alternative to original packs, delivering up to three times the runtime per charge and a lighter weight feel that reduces fatigue during extended use. The review covers fit, charging behavior, protection features and real-world usability with common Craftsman 20V tools.

Key Features

• High capacity: Each 6.0Ah battery offers extended runtime that can power drills, impact drivers, saws and vacuums for longer tasks between charges.
• Fast charge capability: Top A grade lithium-ion cells provide quicker recharge cycles so tools are back in service sooner after heavy use.
• Compatible fit: Designed to 100% fit original Craftsman 20V lithium-ion chargers and replaces CMCB202, CMCB204, CMCB205 and CMCB206 models for seamless swaps.
• Lightweight design: About 20% lighter than comparable Ni-Cd packs, which reduces user fatigue during prolonged handheld use.
• LED charge indicators: Three LEDs display remaining battery power so users can monitor charge at a glance and plan work to avoid downtime.
• Built-in protection: Integrated circuit protection prevents overcharge and short conditions and allows safe storage without capacity loss.

Who It's For

This pack is best for DIYers, landscapers and contractors using Craftsman V20 tools who want noticeably longer runtime without changing chargers or tool mounts. The higher capacity is particularly useful for multi-hour jobs like trimming, drilling or cleanup where frequent battery swaps slow work down.

Users who own Craftsman 20V max Bolt-On or DieHard series should look elsewhere because these batteries do not fit those specific models. Also, those needing OEM warranty support may prefer factory-branded batteries if brand-specific service is essential.

Pros & Cons

Pros

• Higher capacity delivers extended runtime that reduces battery swaps on long jobs.
• Fast charging and A grade cells help get tools back to work sooner after heavy use.
• Seamless fit with Craftsman 20V chargers and common V20 tools makes installation simple.
• Three LED indicators provide clear remaining-charge feedback to plan work.

Cons

• Some users report mixed long-term charge retention, so occasional units may fail to maintain full charge after many months.
• Not compatible with Craftsman Bolt-On and DieHard 20V variants, limiting use for those lines.
