KUNLUN6.0Ah HPB18-OPE 18 Volt Lithium-Ion Battery Replacement for Black and Decker 18V Battery HPB18 HPB18-OPE 244760-00 A1718 FS18FL FSB18 Firestorm Cordless Power Tools

I was ready to throw away my weed whacker; the 18v batteries that came with it didn't run long enough to cover my normal-sized yard, and it would gradually turn slower and slower as the battery lost power, just slapping the weeds! This new battery has a lot more power and the weed whacker runs faster than ever! And it keeps turning just as fast until the battery is spent, which is at least twice as long as my old batteries. The indicator lights on the battery are very helpful. And it charges fine with my old charger.

Charged up well and runs my hedge trimmer as expected.

I hardly ever write an Amazon review but this battery is so IMPRESSIVE I have to say something. My old B&D blower has new life, it's better than it ever was. The battery lasts substantially longer than the original. I like the battery strength indicator too. There's nothing not to like about this, except that it was a tight fit when I first got it so I had to use a file to shave off a little bit of plastic on my blower.

It holds a longer charge than the original Black and Decker batteries. It also charges in a fraction of the time. We’ve only used it once.

I don’t know why I waited so long to replace the battery in my grass trimmer, but I finally did it. This replacement battery works great and has a great charge. I was to the point of just getting a new trimmer, but decided to try this out. I’m so glad I got this battery and have never very happier with its durability and performance.

Battery worked great, until it didn't. Was out using it in the yard, trimming bushes, and then it cut out. The battery showed it still had charge with is led indicator (one of the four LEDS lit). Measured the voltage, it had 12.75 volts on it. Im guessing I hit some threshold where the battery used too much power. But unable to charge back up since. Useless even though there was still charge in the battery.<Update>Very Impressed Kunlun, quickly reached out to me and sent a replacement. Thank you Kunlun, great job keeping a client happy. Will definitely be buying from you next time.

I like the product just fine and I use it for my drill. Good value and I received it the next day.

This is the perfect replacement battery for my Black and Decker hedge trimmer. It lasts much longer and doesn’t need to be charged that often.
