Is the 9.0Ah battery worth it over the smaller V20 packs?

Yes if you run saws, blowers or grinders that drain small packs fast. For drills and drivers, a 4.0Ah pack is lighter and usually enough.

Does it fit all Craftsman V20 tools?

It fits tools and chargers in the Craftsman V20 20V Max line. It does not fit the older Craftsman 19.2V C3 tools or other brands.

How long does it take to charge?

Charge time depends on the charger. On a standard V20 charger expect a long wait for a 9.0Ah pack; a fast charger cuts it substantially.

The battery alone. Chargers and tools are sold separately unless a listing says otherwise.

Battery prices drop around Black Friday and Father's Day sales and when two-packs are bundled. The $38.98 eBay price as of November 4, 2026 is already near the low end.

Our take on the Craftsman V20 9.0Ah Lithium Ion Battery

The Craftsman V20 9.0Ah Lithium Ion Battery is a high-capacity pack for the V20 cordless line, sold as a standalone replacement or upgrade. Craftsman claims up to six times the capacity of the standard V20 battery and uses high-energy cells aimed at heavy-duty jobsite use. At $38.98 at eBay as of November 4, 2026, it sits at the low end of its recent range, well under typical retail for a 9.0Ah pack.
