This kit includes 2 x 2AH batteries, which is essentially the MCB202-2 bundle that is the latest CRAFTSMAN battery sale we spotted this week.

What's the difference between CRAFTSMAN Drill CMCD713C1 and CMCD713C2?

The difference between CRAFTSMAN CMCD713C1 and CMCD713C2 can be found in the last digit of the serial number, which corresponds to the number of batteries included in the kit. This signifier is similar to how many brands distinguish bulk battery packs from each other, like Milwaukee 48-11-1850 that has one battery and Milwaukee 48-11-1852 that has two batteries in it.

The naming convention for this kit doesn't follow the CRAFTSMAN way of labeling their battery bundles though, which adds a "-2" after the base serial number to identify it as a 2-pack — CMCB202 vs CMCB202-2 for example.
