  • Good Run Time
Works great if you don't want or can't use a larger battery. Plenty of juice to run my DeWalt vacuum.

  • Good battery.
very good

  • High quality as expected. Good deal at the time.
Nice and stable. Nothing like OEM dewalt if you are into the yellow brand. Works great as expected.

  • Perfect Addition
Bought as an extra backup for the 4.0 included in my 20v DeWalt multi-tool kit. Size and design are as described. Battery charges quickly and so far gives expected performance. Cost is a little high but it will last longer than the 18v NiCads that I’ve used since prehistoric times! Item arrived as promised and was packaged well. Will buy again from seller. ... show more

  • Delivery Time
Battery works fine, however delivery was 16 days. Vendor indicated they ship in two days, shipped at 14 days. Becoming the norm for Amazon.
