New 9a/h battery won’t charge
We got 8 if these 60 volt 9/ah batteries and after one week and one charge one will not charge back up. Only reason for the 3 star rating.

Battery came part of a leaf blower I purchased at Home Depot less than a year ago. Battery is already dead...after only ~20 uses. Not good!

Way to expensive for a poor fitting case
I have 4 of these and it is PAINFUL to snap them in ALL my DeWalt Tools. Totally sucks. I wish I never spent the money, and I need them because ALL my tools are Dewalt, and I am a carpenter by trade.

If you use your flex volt tools a lot these are the way to go. They add some weight vs the 6 amp hour batteries but it’s worth the runtime. Some tools feel better balanced with the 6 amp and some with the 9 amp which is something to consider as well. If you put four of these on the dcb1800 you will get a max runtime of 720 watt hours. At least until they come out with the 12 amp hour version.
