Are the batteries the same in both?

Yes. Both bundles contain two DCB205 20V MAX XR 5.0Ah packs with a 3-LED fuel gauge and 1.4 lb weight. The only hardware difference is the charger in the kit.

Which is better if I already own a DEWALT charger?

The DCB205-2 two-pack. You pay $110.14 at Significant Services Inc as of November 3, 2026 for the same batteries and skip a charger you do not need.

Is the kit worth the extra $13.96?

Yes if you have no 4-amp charger. A standalone DCB1104 costs more than that difference, and the kit's charger also handles 12V and 60V MAX packs.

How long do these batteries last per charge?

DEWALT rates the 5.0Ah XR pack at up to 60% more capacity than the standard 3.0Ah DCB200. Expect longer runtime in high-draw tools like circular saws and grinders, less gain in drills and impact drivers.

Do they fit older 18V DEWALT tools?

No. These are 20V MAX packs and fit 12V, 20V and 60V MAX tools and chargers only, not the older 18V stem-style line.

Which has the better price history?

The kit has a tracked range of $110.00 to $129.99 in late October 2026, so $124.10 is mid-range. The two-pack's history was not given, so compare its $110.14 against the kit's low before buying.
