Review on Long-Lasting EBL 9V Lithium Rechargeable Batteries With USB 5400MWh Capacity (Pack Of 2) by Cliff Gibs

Won't go through all the details. Let's just say that, through a lifetime of injuries of many types, pain is a constant companion. Neurosurgeons cringe at my MRI's. Even the spinal implant didn't help, but tens units DO. Thing is, they eat batteries. Eat them, and eat them, and eat them. I can use 2 9v's in a day. Don't ask me why I waited so long, but I'm *really* glad I found these. They hold a charge well under a heavy load, deliver what I need for hours, recharge quickly. If I'm out and around, I'll keep one running and one in my pocket. When I get home, I can use the charging cord to charge both at once. Get some.
