Our take on the DeWalt DCB346-3 20V MAX Lithium-Ion Battery 3-Pack

This is a three-pack of DeWalt 20V MAX 4.0 Ah lithium-ion batteries, the mid-capacity pack in DeWalt's cordless lineup. Each battery has a built-in LED fuel gauge and no memory effect, so it can be topped up between jobs without losing capacity. The 4.0 Ah size sits between the compact 2.0 Ah packs and the high-capacity 5.0 Ah and FlexVolt options: more runtime than the small packs, lighter and cheaper than the big ones. It fits every DeWalt 20V MAX tool and charger, and owners rate it well for keeping several tools running without swapping packs constantly.

Pros
  • Fits the whole DeWalt 20V MAX tool and charger line
  • LED fuel gauge on each pack shows charge level
  • No memory effect, so partial charges are fine
  • 4.0 Ah gives solid runtime at moderate weight
  • Three packs keep multiple tools working in rotation
Cons
  • Charger not included
  • 4.0 Ah is less runtime than 5.0 Ah packs
  • No self-discharge claim still means packs drain slowly in long storage
  • Bulkier and heavier than compact 2.0 Ah packs

Questions and answers

Do these batteries fit all DeWalt 20V MAX tools?
Yes. They use the DeWalt 20V MAX slide-on mount and work with every 20V MAX tool and charger in that line.
Is a charger included?
No. The three-pack is batteries only; any DeWalt 20V MAX charger will charge them, with a typical charge time around 45 minutes.
How does 4.0 Ah compare with 5.0 Ah?
The 4.0 Ah packs give somewhat less runtime per charge but weigh less and are smaller, which suits most general and heavy-duty tasks.
Can I leave these on the charger?
DeWalt lithium-ion packs have no memory effect, so partial charges are fine. For long storage, keep them at room temperature and top them up occasionally.
Are these genuine DeWalt batteries?
The DCB346-3 is DeWalt's own three-pack of 20V MAX 4.0 Ah packs, with the yellow housing and LED fuel gauge.
