DeWalt DCB184X2 18v 5Ah Li-Ion XR Slide Battery Twin Pack DeWalt DCB184X2 18v 5Ah Li-Ion XR Slide Battery Twin Pack

I wish that I could have bought these years ago because they are excellent. Putting up metal siding and driving hundreds of screws per day a battery charge would last up to three days where the old style battery required charging every hour or two.Batteries came earlier than expected date somehow but very pleased about that. Once charged they are great and have tons of power. I have had one on my work radio for a whole week now and it hasn’t even dropped a bar yet The battery works in tandem with DeWalt’s smart XR tools, all of which have intelligent switches and motors, so all of the extra capacity the battery holds will be drawn from it in the best way possible for the tool to get the job done as you need it.
