I'm planning to buy the DeWalt DCV501HB shop vacuum for detailing my car and possibly the DCC020IB tire inflator too. I was considering getting two 9Ah FlexVolt batteries (DCB609), but I'm wondering if that's too much. Should I go for multiple 6Ah batteries instead, or would a different size be better?

I'd suggest picking up a couple of 4Ah or 5Ah 20V batteries. They work great with both the vacuum and the inflator. Plus, they’re not too heavy or expensive, making them a solid choice! ?

How long can you use the 5Ah batteries on those tools before needing to recharge?
