This is a used Genuine OEM Black & Decker PS140 Power Pack 14.4V Fire Storm Battery. It has only been tested with a meter as shown in the photos. It isn’t fully charged and I don’t have the charger to test it. I also don’t know how long the battery stays charged for. What you see in the photos is what you will be receiving. Should you have any questions or would like more photos please let me know. There are scratches and scuffs so, please review the photos for any wear and tear. Thank you!
