    • Great replacement battery
Big improvement! Battery is strong and lasts way longer than my 2 ap hr battery. Used it for my black and decker pole saw. Amazing!

Work okay. Runs out of power a little quicker than I liked but okay for the money.

Fast charging and long lasting use for my old Black and Decker Weed Eater. Great purchase.

    • Even better than the original battery ever was !
I've been using these batteries since last summer. I think these are super comparable to the other name brands like Black-n-Decker, which is the brand of my weed eater. The current price of a replacement battery (one battery) for my weed eater is over $50.00 at the local home improvement store. The charge on these batteries is better than my original battery was. The fit on the weed eater is very good and I would definitely recommend this product. ... show more

    • Works with LST300
Cordless weed wackers are great. Better for the environment, convenient and easy to use. Except the batteries only last 20 minutes and take 5 hours to charge. Now I have 3 batteries and can wack away for a whole hour! These batteries last 20 minutes and only take 4 hours to charge. They are hard to get on and off my black and decker charger (hence the 4 stars). They clicked into my LST300 no problem though. I cannot speak on their durability at this point. Hopefully, they last for years like the B&D batteries. ... show more
