It’s almost impossible to find these 9Ah batteries locally – you need to order them online. I’m guessing it’s because they’re too expensive, and for most guys the 6Ah FlexVolt battery is just fine. I got lucky and found a 2-pack for $49.

I have to admit that these batteries add an impressive amount power to my 20v lineup. I’ve only used these on my 20v weed wacker so far and I get about an hour use on high. Battery pack didn’t even get warm. Usually I’ll get around 30min with the 5.0ah. I think it lasted around double the time because the load is spread out with 15 internal 18650 batteries in the 20v/60v vs 10 18650 batteries in the 20v 5.0ah pack.

I’ve been using the 5 and 6 ah batteries for a year or so, but these 9ah batteries are seriously impressive. Recently used one of these on my DeWalt 20v Impact hammer with a 3 1/4″ concrete core to drill through 5″ thick concrete with ease. After 15 minutes of hard use, it only discharged 1/3 of the battery. (Two of the three status LED’s were still lit). That would usually almost drain one of my 5 ah batteries. Definitely worth the money. Also works great in my 60v Flexvolt DeWalt chainsaw. Very powerful!
