Powerextra 2 Pack 3.7Ah 18Volt Replacement Batteries Compatible with Black and Decker HPB18-OPE HPB18

Michael: These were a perfect fit for an older Black and Decker clamp saw. Grandpa is happy that he can use his saw again! He had been told by others that there was nothing they could do since it’s discontinued. Highly recommended.

Brandi: One of the batteries is great, but the other doesn’t last as long. Battery life is about 15-20 minutes. Not as good as brand name, but still a good replacement for the price!

G. Rise: These have worked really well for our black and decker trimmer. We do a handful of other lawns so they get more use than just our yard and they may not last more than a season or two but they have worked well compared with the others we’ve had. If there’s a lot of trimming on a large yard, I sometimes have to use both batteries on one lawn but overall I’m still happy with them and their compatibility and price.

Warren: All of my old Firestorm batteries were at least 12 years old or more. These appear to be well made, direct replacements for them. I was concerned at first, these have three prongs, my old ones had two prongs.
These batteries fit my drill and chainsaw perfectly. More importantly, my tools are working like they were brand new. My old chargers fit them as well. I decided to buy a new fast charger for these. The fast charger gives me real time charge status of the battery. The old chargers didn't give me that info. I checked on replacement batteries 10 years ago. Back then they were ridiculously expensive. Glad I found these, a very reasonably priced alternative with higher capacity than the original batteries.

locoadele: I have found a fix for this battery failing to latch in my Black & Decker Firestorm tools. Turn it over and you will see the spring-loaded latch on the bottom. Looking at it from the side, it is a right triangle. I took my Dremel Tool and a medium grade straight cylindrical grinder and shaved just a little off the top part along the back of the triangle (this is the part that is perpendicular to the bottom of the battery. It was just a little too wide there and the latch would not go all the way into the groove on the tool. I can now latch the battery. I have two of them, one latches by itself and the other I must push down to latch. They may be difficult to remove, but some of my B&D batteries are, also. I just use a slip-joint pliers to pull the latch back up. Taking a little bit more off the latch might fix this, but since I have something that works now, I hesitate to ruin a $40 battery by fiddling with it too much.

I am very pleased with the performance of these batteries. The start out faster than most of my B&D ones, and they maintain good operating speed much longer. I have mainly used them with a 10 in. string trimmer. I have several of these Firestorm...
