Our take on the Craftsman 4.0-Amp Hour V20 Lithium Ion Battery

This is a spare or replacement 20V max lithium-ion pack for Craftsman's V20 cordless line. At 4.0 amp-hours it sits in the middle of the V20 range: twice the capacity of the compact 2.0Ah pack, half the 9.0Ah flagship. It fits the V20 drills, impact drivers, saws and trimmers that share the slide-on mount, and the built-in charge indicator shows remaining power without a tool. Owners like the runtime for mid-size jobs; the common complaint is weight in compact tools and slower charging on the basic charger.

What reviewers say

Owners treat it as a dependable everyday pack that extends V20 runtime without the bulk of the largest batteries. Complaints center on charge time on the standard charger and the added weight in small tools.

What people mention
  • RuntimePraisedOwners say it runs mid-size tools far longer than the compact 2.0Ah pack.
  • WeightMixedSome find it noticeably heavier in compact tools, while others accept it for the extra runtime.
  • ChargingCriticisedRecharge time on the standard V20 charger is called slow by several owners.

Questions and answers

Which Craftsman tools does this battery fit?
It fits tools in the Craftsman V20 cordless line, including drills, impact drivers, saws and outdoor tools. It does not fit the older 19.2V tools or the V60 line.
How does it compare with the 2.0Ah V20 pack?
It stores twice the charge, so tools run about twice as long, but it is larger and heavier. The 2.0Ah pack suits light work and compact tools.
Is it worth buying over the 9.0Ah pack?
For most drilling, driving and cutting it is the better balance of runtime and weight. The 9.0Ah pack is for long, heavy jobs where weight matters less.
Does it have a charge indicator?
Yes. A built-in gauge on the pack shows how much charge is left.
Can I leave it on the charger?
Craftsman's V20 chargers manage the charge cycle, but for longest life store the pack off the charger at room temperature.
Is it a genuine Craftsman battery?
It is sold as a Craftsman V20 lithium-ion pack. Check that the pack carries the V20 label, since third-party packs may not fit or may void tool coverage.
