battery life.
The battery does not last long.after using them 3 or 4 times they quit charging.
Reviewed in the United States on October 23, 2020 by Kindle Customer

It works
This battery is a perfect match for the Black and Decker 40 volt lithium battery. It arrived fully charged. After a brief test, I set it aside for about a month until it was time to use the string trimmer. It was still fully charged, worked fine and lasted just as long as the B&D original. Then it recharged with no issues in the B&D charger. No negatives at all. ... show more

Just what I needed...
The original battery in my string trimmer would go into thermal shutdown multiple times during use. This cured that problem big time. Uses a small percentage of total charge too (old battery would be practically dead). It’s like I have a new trimmer again! Great product at a fair price!!

Replacement battery
Works great, long life on charge. Fit into tools like original batteries. check the date on batteries when purchased, lithium batteries are only good for 2-5 years. Old batteries that are weak were 3 years old.

It works!
I purchased the battery for my B&D edger. It is a strong battery. It charges quickly.

Batteries dont last, would not recommend
I dont think Im asking for the stars but here it is 2025, about 3 years after I bought two of these and the batteries, both of them dont work anymore. One charges but when I use it in the black and decker mower it stays on for 5 seconds, the other one wont even register in the charger! I have kept these batteries inside during the winter and always took them out of the mower when not using and were kept dry. Sorry not sorry, I wouldn't recommend these batteries, not cheap but cheap. Most batteries in brand names like ryobi black/deck etc, have a 5 year guarantee. Guess I am out of the $70plus bux I spent getting these. ... show more

Replacement
This is an add on battery for one that finally stopped charging. So far so good,but I will write more after I've had a chance to see how long the charge lasts in this new battery.

Great battery!
Was looking fir a replacement battery for our weed whacker and found this. Hold the charge long enough for our yard--I think about 30-40 minutes. Arrived really fast!
