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

These rechargeable 9 volts are absolutely great. They work very well, super easy and convenient recharging. The problem I have is I bought these batteries to use for my active pickups in my guitar as well as my guitar pedals. These batteries admit RF noise making them pretty much useless for those applications unless you are looking for that classic hum tone. I've read others have used RF chokes to control the problem, but I really don't have the room inside my pedals to do that and I'd rather not add more wiring to the cavity in the guitar.
