  • Value for your money 100%
Size: 2 Pack 4000mAh
These are just as good as DeWalt. Last long and preforms as well as other brands.

  • Great product at a great price!
I purchased these batteries 11 months ago and they are fantastic! I use them with my Black & Decker yard tools. They work perfectly and last a very good amount of time per charge. The charger is very convenient! Highly recommended, i would definitely buy this brand again. Huge cost savings over the brand name. ... show more

  • More power than my older pack.
Just got this and I am impressed by the power and how long the battery last. It used to take two battery packs to trim our yard, but it only took one with this battery. I think it's definitely a good buy.

  • Came on time, seem to work great.
Work well for half the price of the brand name.

  • Just as good as original, but holds a charge 🤣
Perfect fit to replace original battery on my drill from Walmart that stopped holding a charge due to age. The nrw battery holds a charge well and the color even matches the drill.

  • Better than I expected
I am really impressed so far. I have a few B&D tools that use this battery. The old batteries work but the leaf blower really drains the batteries. I tried the new batteries in the blower today and it went 10 mins solid before I turned the blower off. Usually I am good to get 3 mins of use from the blower. Longevity is not yet determined but so far I am happy. At the price I paid I should buy two more. I am sure I can do twice as many shrubs as well. Good quality. Batteries are well constructed and look great as well. ... show more

  • Huge disappointment
I'm very disappointed in this product. It won't hardly go in my charger. When I do get them on the charger, they will not hold a charge. I would not recommend these to anyone. Don't waste your money.
