Listing details to confirm

The listing gives inconsistent battery information: its details say “2 D batteries required” while feature text describes two rechargeable 2000mAh lithium-ion batteries. It also claims Makita 18V battery compatibility while listing 21 Volts, and gives different descriptions of included tools. Confirm the battery and kit configuration on the selected listing before buying.
