Is the 2.0Ah battery worth it over the 4.0Ah?

For drills, drivers and lights, yes: it is lighter and cheaper. For saws, blowers or long jobs, the 4.0Ah gives roughly double the runtime and is the better buy.

How long does it take to charge?

About 30 minutes on the Craftsman CMCB104 fast charger. A standard charger will take longer.

Will it fit my older Craftsman V20 tools?

Yes. It works with any Craftsman V20 20V MAX cordless tool and charger in the V20 system.

Does it come with a charger?

This listing includes the battery and a charger. Confirm the charger model before buying if you already own a fast charger.

Single-pack prices swing widely. At $29.99 at eBay as of November 4, 2026, it is near the bottom of its recent range, so this is a good time to buy a spare.

Our take on the Craftsman V20 2.0Ah Lithium Ion Battery

The Craftsman V20 2.0Ah Lithium-Ion Battery is a spare or replacement pack for the V20 cordless tool line. It charges in about 30 minutes on the CMCB104 fast charger and has a 3-LED charge gauge. At $29.99 at eBay as of November 4, 2026, it sits at the low end of its recent range, well under the $50-$60 typical for a single 2.0Ah pack.

Best forOwners of Craftsman V20 drills, saws and trimmers who need a spare packLight-duty jobs where a compact, light battery is enoughBuyers replacing a dead pack without buying a new tool kit

Pros

Charges in about 30 minutes on the CMCB104 fast charger
3-LED gauge shows charge level at a glance
Weighs only 0.27 lb, so it keeps tools light
No memory effect and very low self-discharge for storage
Fits every Craftsman V20 cordless tool

Cons

2.0Ah is small; high-draw tools like circular saws drain it fast
Single pack only, so runtime is limited without spares
Older V20 packs and chargers vary, so check compatibility
No fuel gauge beyond three LEDs, so remaining time is rough
