Working great

"The charge checking button needs to be larger. The bottom and sides need to rubberized to protect from impact. These batteries are smaller than the other manufacture's batteries for the same ampere hours. I've got 5 of them now. I 've stop using the Kreg 20V Blue Ion™ 2. 0Ah and 6. 0Ah Batteries, gave them away to Goodwill with the small Kreg 20V Blue Ion™ battery chargers. What I don't use I donate. I use the Kreg 20V Blue Ion™ 4. 0Ah Batteries in the following tools; Kreg® Edge 20V Ionic Drive™ Loose Tenon Joiner, Kreg 20V Ionic Drive™ 1/4" Trim Router, Kreg Rebel™ 20V Ionic Drive™ Pocket-Hole Joiner, Kreg 20V Ionic Drive™ 1/2" Compact Drill and the Kreg 20V Ionic Drive™ Impact Driver without a problem. I probably charged each battery at least seven time each. No issues with the batteries. The only thing that I'm worried about is one of them hitting the floor. I've keep them in the middle of the bench. I've dropped my Milwaukee, DEWALT and FLEX batteries several times over the years. They just bounce. The Kreg 20V Blue Ion batteries remind me of Makita batteries."

Great battery

"Plenty of power to use in the new pocket hole joiner. Made a bunch of holes with the joiner and the battery level was still on 4 bars when I was done. Bought another one on the odd chance I run one down so I have a spare not to delay a project."
