2Pack 4.5Ah HPB18 Ni-Mh Replacement Battery for Black and Decker 18V Battery HPB18 HPB18-OPE Compatible with Black Decker Battery 18 Volt Tools A1718 FS18FL Firestorm Cordless Power Tool（2Pack ）

Exact fit as replacements to mine that finally died after several years of use. Let’s hope these last as long!

Battery worked great. Ni-Mh )cells big improvement over Ni-Cad cells in original batteries.

I kept the shipping box until I tested the fit on my ancient B&D chainsaw. The original battery was shot, had very short run-time when fully charged. Both these batteries fit perfectly in the original charger (one was already fully charged), but very tight fit in the tool. I'm guessing that, over time, they'll slide in easier. Threw the box away. Haven't tested run time yet, but I doubt it's worse than the original (given the Ahr claimed upgrade by mfr). 5 stars if the Ahr upgrade makes a noticeable difference.

Great value Powerful charge

Very happy with the ability to secure batteries for an older technology B&D cordless drill, getting two batteries for a good price very attractive.

Shipped fast. Have power when I received. I charged fully, then first use was after one week. each battery run full speed about 10 min. Second use was afetr a fully charge, it ran full speed about 15 min. It's a good fit to my tools. I like them.

While looking for replacement batteries for our Black and Decker yard tools (first ones using batteries), we were shocked to learn the short lifespan. Somehow, our original battery lasted 6yrs, which we now know is not the norm. This battery charged fast and lasted at least 1hr between the hedge clippers and weed whacker. We have a large yard (of the 3 acres, we mow/groom 3/4 of an acre), lots of beds/bushes/ornamental trees. Plus we butt up to woods and wetlands...lots of maintenance overall! It is a tight fit to get it in, but well worth the money. It is stronger than the original that came with the tools. We can't rate longevity, as we just got them, but for the other categories a definite 5 stars!

I advise against purchasing these batteries. Despite following the recommended charging instructions, I found that they lasted only five to ten minutes during use. Initially, I suspected my charger was faulty and purchased a replacement, but the batteries continued to provide only five to ten minutes of power. In my experience, these batteries offer limited long-term value unless used for tasks requiring no more than five to ten minutes of operation.
