2Pack 20V 3.5Ah Replacement for Craftsman 20V Battery - Fast Charger

In this review the 2Pack 20V 3.5Ah Replacement kit is evaluated as a budget-friendly battery and charger alternative for users of Craftsman V20 tools. The bottom line: it is best for homeowners and light trade users who need extra run time and a fast replacement charger, because the pair of 3500mAh lithium-ion cells deliver solid battery life and the included 20V fast charger refills a compact V20 pack in around 1-2 hours. The review notes both reliable performance and a few reports of inconsistent long-term charging from some users.

Key Features

• Battery Capacity: The 3500mAh 20V lithium-ion cells provide longer runtime for handheld drills, lights and blowers compared with smaller replacement packs.
• Included Charger: The 20V fast charger supports universal 110V-220V input and can recharge V20 compact batteries in approximately 1-2 hours, reducing downtime between jobs.
• Compatibility: Works with a wide range of Craftsman V20 battery models such as CMCB204-2, CMCB202-2, CMCB201 and similar V20 packs used across drills, chainsaws and blowers.
• Safety Protections: An intelligent built-in chip protects against over-charge, short-circuit, over-heat, over-load and low-voltage, helping preserve cells and reduce risk during charging.
• Durable Construction: The shell uses fireproof A0-class material and high-quality cells to extend service life and improve long-term durability.
• Value Pack: Two replacement batteries plus a fast charger make this kit useful for users who need immediate spares and the ability to keep multiple tools ready.

Who It's For

This kit is ideal for homeowners, hobbyists and light tradespeople who use Craftsman V20 cordless tools and want extra runtime without paying for OEM packs. The two 3.5Ah batteries give the flexibility to keep one pack in use while the other charges on the included fast charger.

It is less suitable for heavy professional users who demand factory service warranties and long-term commercial reliability, or for anyone using Craftsman 20V max Bolt-On series packs, which this kit does not fit. Those customers should consider OEM or Bolt-On specific packs instead.
