Keep your tools charged and ready to go in a moment's notice with the V20 4.0Ah Battery and Charger Kit. It is built to charge compatible CRAFTSMAN V20 lithium-ion batteries for shop, home, and jobsite use.
What does the CMCB204-CK include?
The kit ships with one 4Ah V20 battery and a charger — a straightforward upgrade path for V20 users who need a higher-capacity pack without buying a full multi-battery kit.
When should someone buy the 4Ah battery instead of adding another 2Ah pack?
A 4Ah battery holds twice the charge of a 2Ah pack, giving longer runtime between charges on the same tool. For tools used in extended sessions — outdoor equipment, circular saws, reciprocating saws — the longer runtime per charge is worth the extra cost over a second 2Ah battery.
Who is the CMCB204-CK the right buy for?
This kit suits V20 owners who already have a tool setup and want to add a dedicated high-capacity battery. It is also the right starter if you expect to use V20 primarily for outdoor tools like blowers, trimmers, and chainsaws where 4Ah is the practical minimum.
How does the CMCB204-CK compare with the CMCB204-CKVA starter kit?
The CMCB204-CKVA includes both a 2Ah and a 4Ah battery with a charger — two packs for more versatility. If you already own a charger and just need a 4Ah battery, the CMCB204-CK avoids paying for another charger. If you are starting fresh, the CKVA gives you two different capacity packs in one purchase.
Can the charger included with the CMCB204-CK charge all V20 batteries?
Yes. The included single-port charger works with any V20 battery capacity — 1.5Ah, 2Ah, 4Ah, 6Ah, and others in the V20 lineup. Charge time scales with capacity; the 4Ah pack takes roughly twice as long as a 2Ah pack to fully charge.
