Review on Biswaye 2-Pack 3.8Ah 18V NI-CD Battery - Compatible with Black & Decker HPB18-OPE 18-Volt Slide Pack Battery HPB18 244760-00 A1718 FS18FL FSB18 - for 18-Volt Firestorm Cordless Power Tools by Travis Filippi

The question is, will these batteries last more than 15 minutes of use? The OEM version of these Black and Decker 18V batteries are no longer manufactured and the gray market has taken their place. this gap in the supply chain. Consumers are still using their B&D devices, which need to run on those 18-volt batteries. What is the difference? The batteries come in packs of 2 and are a different colour, more reddish than orange. Tested: Immediately insert a battery for 8-9 charging cycles. I'll see how long it takes to charge. It took 9 hours to charge with the charger shown in the photo. If using hold charge, how long do these batteries hold a charge? The battery lasted 20 minutes when the trimmer was on. /Weed Wacker.This battery has been replaced: BLACK+DECKER 18VNiCd Single (HPB18-OPE) battery which you can see in the third photo I uploaded for this review.Note: Date of first charge is September 13, 2020.
