Does the DCCS620B come with a battery and charger?

No. It is sold as a bare tool. You need a DeWalt 20V MAX battery and charger, which are sold separately.

What size wood can it cut?

It handles branches and logs up to roughly 6 inches well. Larger cuts are slow and drain the battery fast.

It accepts DeWalt 20V MAX batteries. Larger-capacity packs give longer runtime but add weight.

No. It is a pruning and limbing saw. For felling or large logs, a larger gas or higher-voltage saw is a better fit.

Yes. Fill the oil tank before each use and check it often, because the reservoir is small.

It is more compact and cheaper to run if you own 20V batteries, but 40V saws cut faster in bigger wood.
